beauty equipment shell

 

This is the shell of the beauty equipment customized by our company for the customer. This product is large in size, relatively heavy, and has high appearance requirements. We use injection molding. There are also a lot of beauty equipment shell is made of FRP material, but the performance of the shell assembly of FRP material is poor, and the screw and FRP material connection degree is low. The most important point is that glass fiber reinforced plastic material is not environmentally friendly, very big pollution to the environment

This ABS is made by injection molding. The main component of plastic is polymer resin, that is, synthetic resin. The additive component is relatively less, which can also achieve the effect of light weight and high strength! Although sharp objects scale relatively resistant glass fiber reinforced plastic materials is poor, but plastic hairdressing instrument chassis strong toughness, hardness, balance is good, strong plastic line, streamline can make all kinds of finished products, and the instrument chassis type of activities can be made, easy to assemble again, screw and plastic board is easy to connect, the overall strengthening of chassis, And one of its biggest advantages is that it has little environmental pollution and can be recycled!

Beauty equipment shell often use ABS material, ABS material has excellent mechanical properties, toughness, impact resistance, not easy to damage. The material is easy to process, the finished product has good dimensional stability, good surface gloss, high thermal deformation temperature and good chemical stability. But want to achieve brilliant color effect need to carry out the spray painting process. It is recommended to use non-spraying material to produce the shell of beauty instrument, which can save the spray painting step and reduce the emission of harmful gas.

Precision injection molding characteristics

Precision injection molding characteristics

     The Precision injection molding is generally referred to as the precision of forming parts and surface quality is demanding high technology, some people think that precision injection is the size of plastic parts to achieve the accuracy of 0.01 ~ 0.001 mm injection molding process. In recent years, with the electronic, medical, communications, automotive, and other industries. With the rapid development of people’s plastic products, high precision, high-performance requirements. The traditional plastic molding process has been difficult to meet the current high standards. Is one of the most important plastics molding methods. Therefore, precision injection molding technology more and more people’s attention. Making precision injection molding technology continues to progress, new technology continues to emerge. Factors that affect precision injection molding require high dimensional accuracy, low warpage, excellent transfer characteristics, and excellent optical properties.

Therefore, it is on the injection molding machine, injection mold, molding process, raw material properties. And formulations have special requirements, affecting the many factors of precision injection molding. According to the current actual production point of view, the impact of precision injection molding factors are the following aspects:

1. Plastic shrinkage design of precision plastic products, plastic shrinkage should be considered.
2. The shape and size of the product The shape and size of the plastic parts have a great impact on the accuracy of the parts, the production practice shows that the more complex the shape of the product and the larger the size, the lower the accuracy
3. Mold structure The accuracy of plastic parts and mold cavity number and production volume are closely related. It is also shown that the accuracy of the single-cavity mold structure is higher than that of the multi-cavity mold, and the accuracy of small-mass production is higher than that of large quantities.

Daily plastic products

1, PET, polyethylene terephthalate

Main applications:

The most common use as beverage bottles and other transparent screen protection film protective film. PET can also be spinning, that is, we often say polyester. In addition there are many engineering applications PET

Caution:

Non-toxic, but the synthesis process may remain single, low molecular weight oligomers and side reaction products such as diethylene glycol, these are some toxic, PET raw material for beverage bottles countries have strict standards.

PET plastic higher melting point. But generally do not recommend reusing bottles, especially for loading water. Since PET bottles are generally thin, manufactured using blow molding method, when the bottle is heated to about 90 ℃ rearrange, and the internal stress due to the role of PET molecular chains, and the contraction distortion of the bottle experience, this time using easily result in burns. The higher temperatures will increase the risk of harmful substances in the material eluted.

2, PE, polyethylene (high density polyethylene: HDPE; low density polyethylene: LDPE)

Main applications:

PE is currently the most widely used plastic, with different modification methods, PE can be used in all aspects of daily life. More representative, including plastic buckets, film, paper cups wall, pipes and cable jacket and so on.

Caution:

PE itself is non-toxic. However, the production will be used in processing or modification of some additives, such as fillers, pigments or stabilizing aid. Some additives are toxic. Since PE products will soften or even melt at higher temperatures, you should try to avoid higher water temperatures under 100 ℃.

3, PVC, polyvinyl chloride

Main applications:

PVC is now used for the manufacture of some cheap leather, floor mats, water pipes, etc.; due to its good electrical performance has a certain self-retardant properties, is widely used in the manufacture of wire and cable sheath. In addition, PVC is widely used in industrial fields, especially for acid corrosion in high demand areas.

Caution:

PVC production uses a lot of plasticizer (plasticizer such as DOP) and heat stabilizers containing heavy metals, and the synthesis process is difficult to eliminate the presence of free monomers, which are considered to be toxic. So PVC in contact with the human body, especially in medicine and food applications, is gradually being replaced by PP, PE.

PVC is a non-high-temperature plastic, can not be used at higher temperatures.

4, PP

   Main applications:

   PP is also very broad range of use, everyday items such as packaging, toys, basins, buckets, hangers, cups, bottles, etc.; engineering applications such as car bumpers. PP spun yarn is known as polypropylene, textiles, non-woven fabrics, ropes, nets and other products are common.

Caution:

 PP and PE processing methods and the use of similar, itself non-toxic. Possible threats from the processing and modification additives. Especially due to poor weather PP, used in the production of anti-aging agent may contain heavy metals. Products compared to PE, PP products slightly better heat resistance, typical Lock & Lock glass using temperature can reach 110 ℃, but then there is a high temperature melting softening and dangerous, and should be avoided.

5, PS

Main applications:

Cheap transparent products, foam, CD boxes, cups, snack, insulation lining and so on.

Caution:

Toxic materials for the synthesis of polystyrene by appropriate synthesis process, has very little residual monomer polystyrene, glass, etc. but now has very little use of this material. Polystyrene flammable, especially after PS foam. Combustion will produce large amounts of toxic gases. In some high-level house on fire incidents, due to the insulating layer materials using a PS foam board is widely used, a lot of smoke and toxic gases generated by the fire became the main reason leading to a large number of casualties.

Overview of China Auto Mould

 

Overview of China Auto Mould

China Auto Mould

The rapid development of China's automobile industry has brought a broad development space for domestic automobile molds. In addition, due to cost and market factors. The focus of mold manufacturing in developed countries has gradually shifted to developing countries represented by China. Comprehensive factors at home and abroad have promoted the rapid development of the domestic automotive mold industry. And many emerging automotive mold companies have emerged. According to statistics, injection molds account for about 37%. China has become a veritable automobile mold manufacturing country.

 

China’s automotive mold production capacity is extremely advantageous in the world. However, due to the slow technological improvement of domestic high-end automotive mold companies, technical innovation capabilities. And insufficient capabilities in R&D and application of new mold technologies. The development capabilities of domestic high-end molds are not yet complete. To meet the supporting needs of the domestic automobile industry. A large part of high-end automobile molds still needs to be imported. Therefore, the domestic automobile mold industry needs to make up for this shortcoming as soon as possible to make up for a major shortcoming of my country's automobile mold industry.

 

As China's top ten industries for revitalization

 China Auto Mould

China's automobile industry has been supported by national policies, coupled with the promotion of autos to the countryside. And China's major auto companies have increased their production, reaching 40 million vehicles in 2020, maintaining the world's first position in production and sales. It is understood that about 1,500 molds are needed to manufacture an ordinary car, among which are close to 1,000 stamping molds and more than 500 interior trim injection molds. Affected by the rapid development of China's auto industry. China's auto mold industry has shown rapid growth and its market capacity has continued to expand.

 

With the gradual increase of China's automobile production year by year. Domestic and foreign automobile mold companies have shown their talents in the Chinese automobile market. Meeting the hot domestic demand and export demand to a certain extent. And at the same time. It has created a new generation in my country's automobile mold industry. Good opportunity. It can be seen that the prospects of China's automobile mold industry are very broad.

 

Scientific management and informatization are the development direction of mold enterprises

 

Another important aspect of the development of automobile mold technology is scientific and information management. Scientific management has enabled mold companies to continue to develop in the direction of Just-in-Time Manufacturing and Lean Production. Enterprise management is more precise, production efficiency is greatly improved, and ineffective institutions, links, and personnel are continuously streamlined. With the progress of modern management techniques. Many advanced information management tools, including enterprise resource management systems (ERP), customer relationship management (CRM), supply chain management (SCM), project management (PM), etc., are used in mold companies It is widely used.

 

Refined manufacturing of molds is an inevitable trend

 

The so-called refined manufacturing of molds refers to the development process and manufacturing results of molds. It is specifically manifested in the rationalization of the stamping process and mold structure design. High precision of mold processing, high reliability of mold products, and strict technical management. Sex. Refined mold manufacturing is actually not a single technology, the second is a comprehensive reflection of design, processing, and management technology. The realization of refined mold manufacturing not only depends on technical excellence but also on strict management.

 

China is the world's largest country in automobile production and sales. The number of automobiles is also expected to be the largest in the world, but it has never been able to produce its own high-end cars. This has a lot to do with the lagging development of the automobile mold industry. Which is known as the "mother of the automobile industry". Auto mold refers to the mold used in the automotive field, known as the "mother of the automobile industry". More than 90% of the parts in automobile production need to be formed by molds, and automobile body molds, extensive huge and medium-sized panel molds. Are used for body manufacturing. An important part of technology is also a key link in the formation of autonomous vehicle development capabilities.

Automobile mold products include automobile cover molds, tire molds, interior, and exterior plastic parts molds, automobile lamp molds, automobile bumper molds, automobile dashboard molds, etc.

Die-casting features

 

Compared with other metal forming processes, the Die-casting features are:

(1) productivity is extremely high

The production process is easy to realize the mechanization and automation. General cold chamber Die casting machine every eight hours can be 600 to 700 times the Die-casting, hot-pressing Die-casting machine every eight hours to Die-casting 3 000 to 7 000 times. And a Die-casting mold cavity often more than one, so that the number of Die-casting production will also exponentially increased.

(2) High dimensional accuracy of the casting

The size of stability, consistency, and less processing allowance and a good assembly. Die-casting of the accuracy of up to IT11 ~ IT13 level, and sometimes up to IT9 level. Surface roughness values ​​are generally Ra0.8 ~ 3.2, the lowest up to Ra0.4. General Die castings only a few parts of the size of machining, and some parts without even mechanical processing can be directly assembled to use. This high utilization of materials, up to 60% to 80%, a rough utilization rate of 90%.
 

(3) Casting dense organization, with high strength and hardness.

As the metal liquid is solidified under pressure, and because of high-speed filling, the cooling rate is extremely fast, so that the casting surface to generate a layer of the cold hard layer (about 0.3 ~ 0.8mm), the layer of metal grain is small, dense organization. Therefore, high strength and hardness of Die-casting, solid wear-resistant. When the Die wall thickness is appropriate and uniform, its strength is higher.

 
(4) It can be a complex casting shape

Clear-cut thin-walled deep cavity casting, because of the liquid metal under high pressure to maintain high mobility.
The minimum wall thickness of zinc alloy Die-casting parts can reach 0.3 mm, aluminum alloy is about 0.5 mm. The minimum casting diameter is 0.7 mm and the minimum pitch of the castable thread is 0.75 mm.

Die-casting assembly features

 

(1) The inlay casting method eliminates the assembly process. Simplifies the manufacturing process. Parts of other materials such as magnets, brass sleeves and insulating materials can be embedded directly into specific parts of the die casting to meet specific requirements, eliminating the need for assembly processes and simplifying the manufacturing process.
 
 
(2) Casting the existence of porosity, but generally, still, meet the requirements. As the filling of liquid metal is extremely fast, it is difficult to completely remove the gas entrained in the cavity during filling, which results in the presence of pores and oxidized inclusions in the die castings, thereby reducing the quality of the Die castings. Therefore, the general die casting can not be heat-treated, and should not work at high temperatures. Similarly, do not want to mechanical processing, so as not to expose the pores under the casting surface.
 
 
(4) The size of the Die-casting die-casting machine by clamping force and size constraints mold, so the production of large-scale Die casting production is limited. At present, the large-scale Die-casting machine has been developed, large parts die casting problem is gradually being resolved.
 
(5) The Die-casting process is only suitable for mass production. As the high price of the Die-casting machine, Die casting mold manufacturing costs are high, long hours, maintenance costs are high, so the total cost of production, not small batch production.

(3) Resin requirements for medical plastics with high purity, narrow molecular weight distribution;

(4) Plastic processing or modified in the process need to add various additives. Such as the amount of plasticizer in PVC medical products often as high as 30-60%, thus requiring to maximize the use of toxic chemicals. To prevent long-term use or reduce the precipitation of additives to affect product performance and treatment;

(5) In accordance with the requirements of medical plastic, often need to make products with surface hydrophilicity, anti-radiation sterilization, and other functions.

Troubleshooting for PC plastic molded parts

 

Focus on Polycarbonate Project success

We are very honored, for a Polycarbonate molded parts project between China and US injection mold company. We become the winner.

There is an American medical company needs 1 set of high precision injection molding part, the part we are going to mold is made in PC raw resin, also called Polycarbonate. Although the transparent plastics piece is our strength, in the actual production process, some problems. Our experts cost time and solve it finally, it should be we can learn and share.

Here’s a simple idea about the injection mold for PC medical products.

Deep Injection Molding Manufacturing Expertise

As you can see the transparent body is a hook surface.  The product surface needs to be transparent and no rod traces and dirty marks. We need to ensure that the plastic products will not stick in the side of the cavity during the injection molding process. So it is necessary to use a slider block structure. Because the customer needs all the wall thickness must be uniform, then the light reflection is the same. Look at the pictures and videos can know, for an elliptic shape, the problem is difficult to solve.

 

Another problem is the bubble inside, the product safety reason, customer have to design and make the wall thickness reaches 5 MM, PC accessories will have some bubbles, from the picture you are hard to find, but the actual existence, made a bubble in the PC material parts get cooling and sealing the door quickly,  there are some defects on the surface is easy to produce because of big thickness, to do the right thing, there are a few things you might want to check if the resin completely drying, a suitable mold temperature, injection speed, using multi-point hot runner feeding, etc. here is the final approved sample to see the clean off, there is no bubble at all!

New energy vehicles put forward new requirements for plastics

 

New energy vehicles put forward new requirements for plastics

With the rapid development of the automotive industry, especially the rapid development of new energy vehicles (including hybrid, pure electric, and hydrogen energy). In recent years, the automotive industry has had a demand for lightweight, integrated, miniaturized, and electrified auto parts Also increasing day by day.

Plastic is an indispensable material in the automotive field, and its process and performance requirements are increasingly becoming everyone’s attention. At the same time, higher requirements are also placed on the R&D capabilities and rapid response capabilities of material suppliers.

Miniaturization of turbocharged engines requires high-temperature resistance of plastic materials

The latest development trend of internal combustion engines is miniaturization and intake supercharging (that is, turbocharged high). The huge benefits brought by these two technologies are a significant reduction in fuel consumption. An increase in engine power, and a reduction in overall engine mass. For example, The two-piece structure design of the previous engine intake manifold has been changed to an intake manifold with an integrated intercooler.

This design puts forward higher requirements for the high-temperature resistance and high strength of the material. It needs to withstand high temperatures of 190°C and 230°C for a long time and has excellent strength.

Electrification requires low precipitation and neutrality of plastic materials

As more sensors have been placed in various positions of the vehicle. The integration of electrification continues to improve, and the requirements for materials of this electrified equipment are more stringent than before. Such as low precipitation (not to block the oil circuit of the capillary structure), Electrically neutral (not to cause a short circuit in the circuit), and materials need to meet the requirements of relevant laws and regulations (not to contain prohibited substances), etc.

Polyamide (nylon) materials are widely used in the automotive industry for their excellent mechanical strength and long-term heat resistance. Its heat resistance is related to the heat stabilizer. Common heat-resistant stabilizers include metal salts (such as copper iodide/copper halide, metal stearate, etc.) and aromatic amines (such as aniline substances, etc.). With the increasing awareness of environmental protection, some of these heat-resistant stabilizers have been banned by relevant regulations due to their side effects. For example, the latest EU regulations strictly control N, N’-diphenyl-p-phenylenediamine (DPPD) substances.

New energy vehicle requirements for flame retardant properties of plastic materials

With the rapid development of new energy vehicles (including hybrid, pure electric, and hydrogen energy), related standards for parts and materials in this field are also rapidly refined. For example, requirements for different flame retardant systems, flame retardant systems Cover roughly 5 types, namely. Halogen flame retardant, nitrogen flame retardant, inorganic flame retardant, phosphorus flame retardant. And nitrogen-phosphorus synergistic flame retardant. Among them, the flame retardant mechanism is divided into gas phase flame retardant and corrosive” Carbonized” flame retardant. Such as red phosphorus, inorganic flame retardant, etc.

Different flame-retardant systems have different flame-retardant effects. At the same time have obvious changes in the physical properties of the material (such as density, rigidity, and toughness). So how choosing a flame-retardant system to match the flame-retardant effect and mechanical strength requirements of the components is a very complicated problem that must be solved.

New energy vehicle requirements for thermal aging stability of materials

In the high-voltage parts of new energy vehicles. According to regulatory requirements, bright orange materials are required to mark the relevant parts as high-voltage areas. The components in the high-voltage area tend to continue to heat up after the current is connected. Therefore, most vehicle manufacturers also put forward related thermal aging stability requirements for orange materials. For example, after 90℃+1000h thermal aging, the color change of RAL2003 shall not exceed Darker oranges such as RAL2008 and RAL2009.

In the future automotive industry, lightweight and weight reduction, electrification, high transmission efficiency, and miniaturization of turbocharged engines will surely become a whole. And become the indicators for the development and verification of most highly integrated auto parts. . Material manufacturers also need to actively respond to the market and improve material performance to meet the new requirements of the automotive industry.

The rapid development of China's automobile industry has brought a broad development space for domestic automobile molds. In addition, due to cost and market factors. The focus of mold manufacturing in developed countries has gradually shifted to developing countries represented by China. Comprehensive factors at home and abroad have promoted the rapid development of the domestic automotive mold industry. And many emerging automotive mold companies have emerged. According to statistics, injection molds account for about 37%. China has become a veritable automobile mold manufacturing country.

 

China’s automotive mold production capacity is extremely advantageous in the world. However, due to the slow technological improvement of domestic high-end automotive mold companies, technical innovation capabilities. And insufficient capabilities in R&D and application of new mold technologies. The development capabilities of domestic high-end molds are not yet complete. To meet the supporting needs of the domestic automobile industry. A large part of high-end automobile molds still needs to be imported. Therefore, the domestic automobile mold industry needs to make up for this shortcoming as soon as possible to make up for a major shortcoming of my country's automobile mold industry.

 

As China's top ten industries for revitalization

China Auto Mould

China's automobile industry has been supported by national policies, coupled with the promotion of autos to the countryside. And China's major auto companies have increased their production, reaching 40 million vehicles in 2020, maintaining the world's first position in production and sales. It is understood that about 1,500 molds are needed to manufacture an ordinary car, among which are close to 1,000 stamping molds and more than 500 interior trim injection molds. Affected by the rapid development of China's auto industry. China's auto mold industry has shown rapid growth and its market capacity has continued to expand.

 

With the gradual increase of China's automobile production year by year. Domestic and foreign automobile mold companies have shown their talents in the Chinese automobile market. Meeting the hot domestic demand and export demand to a certain extent. And at the same time. It has created a new generation in my country's automobile mold industry. Good opportunity. It can be seen that the prospects of China's automobile mold industry are very broad.

 

Scientific management and informatization are the development direction of mold enterprises

 

Another important aspect of the development of automobile mold technology is scientific and information management. Scientific management has enabled mold companies to continue to develop in the direction of Just-in-Time Manufacturing and Lean Production. Enterprise management is more precise, production efficiency is greatly improved, and ineffective institutions, links, and personnel are continuously streamlined. With the progress of modern management techniques. Many advanced information management tools, including enterprise resource management systems (ERP), customer relationship management (CRM), supply chain management (SCM), project management (PM), etc., are used in mold companies It is widely used.

 

Refined manufacturing of molds is an inevitable trend

 

The so-called refined manufacturing of molds refers to the development process and manufacturing results of molds. It is specifically manifested in the rationalization of the stamping process and mold structure design. High precision of mold processing, high reliability of mold products, and strict technical management. Sex. Refined mold manufacturing is actually not a single technology, the second is a comprehensive reflection of design, processing, and management technology. The realization of refined mold manufacturing not only depends on technical excellence but also on strict management.

 

China is the world's largest country in automobile production and sales. The number of automobiles is also expected to be the largest in the world, but it has never been able to produce its own high-end cars. This has a lot to do with the lagging development of the automobile mold industry. Which is known as the "mother of the automobile industry". Auto mold refers to the mold used in the automotive field, known as the "mother of the automobile industry". More than 90% of the parts in automobile production need to be formed by molds, and automobile body molds, extensive huge and medium-sized panel molds. Are used for body manufacturing. An important part of technology is also a key link in the formation of autonomous vehicle development capabilities.

Automobile mold products include automobile cover molds, tire molds, interior, and exterior plastic parts molds, automobile lamp molds, automobile bumper molds, automobile dashboard molds, etc.
