Why China mold more and more foreign customers have been recognized

You may hear from someone that plastic injection moulds from China are of low quality. But still, many companies are buying injection molds from China. Some of them with big volume demands even set their own sourcing office in China. Are those companies silly? No. Mold making. The answer is China injection mold makers can manufacture high-quality molds. As good as American and European companies with competitive lower prices. This is why the plastic injection mold makers outside China lost their jobs to the Chinese.

 

Chinese sales are good at language communication and technology

In China, now more and more plastic injection mold makers hire technical sales. Who are good at technique and English communication. As we all know, the technique requirement is the most important thing for an injection mold making project. And now many Chinese mold salesmen are good at CAD drawing, materials choosing, and mold-making process. So they can communicate with the partner engineers very well. To make a new plastic injection mold. The 3D drawing is the first thing and then analyzes how to make the mold (size, structure, material, cut down the cost, and so on). So the key point is how to make the suppliers' engineers and your companies' requirements connection.

Just like our factory, we have cooperated with German and United Kingdom companies for five years. We work well if you have a new custom mold making project next time. You can send your drawing to us to have a test.

After 30 years of development, mold manufacturing becomes a mutual industrial in China

There is a well-developed industrial chain. Many well-trained mold makers, and well-educated businesses developing. And project management employees. Despite they are paid 2/3 less than in the US. They make the first-class mold as your mold maker did in the US.

Injection molding is a manufacturing process for producing plastic injection molds from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, and mixed. And forced into a mold cavity by a reciprocating screw or a ram injector. Where the injection molded part cools and hardens to the configuration of the mold cavity. After a part is designed, usually by an industrial designer or an engineer. Molds are then manufactured by an injection mold company. where it is assigned to a mold maker (or toolmaker).

Injection molding is widely used for manufacturing a variety of parts

Injection molds are usually constructed using either steel or aluminum. Precision-machined to form the features of the desired parts. Injection molding is widely used for manufacturing a variety of parts. From the smallest component to the entire body panels of cars. Injection molding is the most common method of production. With some commonly made injection molded items including computer components to outdoor furniture.

Most polymers may be used for molds. Including all thermoplastics, some thermosets, and some elastomers. There are tens of thousands of different materials available for injection molds. That number is increasing every year. The materials can be mixed with alloys or blends of previously developed materials. This allows product designers to choose from a vast selection of materials. So they can choose exactly the right properties for the injection molded part or parts they need. Mold materials are chosen based on strength. And the function is required for the final part and each material has different parameters for molding that must be considered. Common polymers like Epoxy and phenolic are examples of thermosetting plastics while nylon, polyethylene, and polystyrene are thermoplastic.

What is medical grade plastic?

 Medical plastics are revolutionizing the health care industry. Equipment that has previously been made of steel, ceramic, or glass is now being made of this durable, cost-effective material. There are even several patient treatment methods that now involve medical plastic. Let's learn more about medical-grade plastics and the incredible advantages they offer the industry.

What Is Medical Grade Plastic?

The term "medical grade" means that the products, whatever they may be, come from a seller who operates under a physician's license. In the case of a medical plastics manufacturer, this means a medical director is present to supervise and regulate the materials used to fabricate the equipment.

Medical plastic itself is designed to be temperature, chemical, and corrosion-resistant. That way, it can handle frequent sterilization cycles and any other medical or bodily fluids it comes into contact with. Medical grade polypropylene and medical-grade polycarbonate are two common polymers used in several applications, from MRI casings to surgical tools.

With a better understanding of medical-grade plastics in mind, let's explore a few advantages they have to offer the health care industry.

Compared with ordinary plastics, medical grade plastic is higher

(1) Since most toxic monomers and oligomers. Therefore medical plastics have strict limits on residues of these substances.

(2) Plastic in the polymerization process will inevitably be exposed to the reaction vessel, the metal catalyst, etc. According to the medical plastics national standard, zinc, lead, cadmium, copper, barium, and tin, often contain trace amounts of metal ions. And other metal ions residue situation It is clearly defined.

(3)For medical plastics require a higher purity and narrow molecular weight distribution.

(4) The plastic processing or modification process requires the addition of various additives. Such as the amount of plasticizer in PVC medical products is often as high as 30-60%. Thus requiring far as possible using non-toxic chemicals. To prevent long-term use or reduce the precipitation of additives. So as not to affect product performance and treatment.

(5) According to the requirements of medical plastic. Often need to make products having a hydrophilic surface, and anti-coagulation. Anti-radiation sterilization, and other functions.

medical equipment application of Plastic products

Overall, medical grade plastic is a highly versatile and reliable material that plays an important role in modern healthcare. Its biocompatibility, durability, and customizable properties make it an ideal choice for a wide range of medical applications, from surgical instruments to i

A Comparative Analysis between China and Us Injection Mold Industry

The domestic total output of 4,500 tons of production line 250 people. The United States to improve equipment, with the production capacity of two production lines 180 people. According to the domestic monthly salary plus a total of 4500 yuan of various types of social security costs. In the United States, no one monthly salary plus insurance costs a total of 3,600 US dollars per ton of labor costs: domestic 250 * 4500 yuan/month / 4500 tons/month = 250 Yuan/ton, equivalent to 40.32 US dollars/ton. Which does not include the company providing accommodation and other expenses. The United States is 180 people * 3600 US dollars / month / 4500 yuan / month = 144 US dollars / ton, 2.57 times higher than the domestic.

2, The depreciation cost, the US depreciation cost is 1.7 times the cost of domestic depreciation.

With the production capacity of equipment and land plant. The domestic production line investment 90 million yuan. The US production line investment 25 million US dollars. According to 15 years depreciation with an annual output of 50,000 tons, respectively, calculated tons of depreciation costs: domestic 90 million / 15 years / 50000 tons/year = 120 Yuan/ton, equivalent to 19.35 US dollars/ton. The United States is 25 million US dollars / 15 years / 50000 tons / year = 33 US dollars / ton, 1.7 times higher than the domestic.

3, Plant construction costs: US plant construction costs are 4 times that China

While the United States its own favorable conditions can not be ignored.

1, Land costs: China is 9 times the United States

Domestic land price is 9 times the US land price, and the United States is a permanent property right. We are 50 years of property rights. For example, in recent years, the price of industrial land in Shanghai is 180,000 yuan/mu. The current US land price is only 20,000 US dollars/acre, equivalent to 20,000 yuan/mu.

2, Logistics costs: China is the United States 2 times

Domestic logistics costs are twice the cost of US logistics. To oil prices, for example, China’s oil price is twice that of the United States, high oil prices are high logistics costs.

Why precision injection molding is difficult?

 

Why precision injection molding is difficult?

 

Injection molding:

it is an injection molding method. The injection molding method has the advantage of production speed, high efficiency. It can realize automation operation, breed of design and the color is much, can shape by Jane to numerous. It can from big to small size, and precise in dimension and product upgrading. Can into complex shape parts. Injection molding is suitable for mass production with complex shape products and processing fields.

After a product is designed, usually by an industrial designer or an engineer. Molds are made by a mold maker (or toolmaker) from metal. Usually, either steel or aluminum and precision-machined to form the features of the desired part. Cost savings are highest when components have a minimum wall thickness. As long as that thickness is consistent with the part’s function and meets all mold filling considerations. As would be expected, parts cool faster with thin wall thicknesses. This means that cycle times are shorter, resulting in more parts per hour. Further, thin parts weigh less, using less plastic per part.

On average. The wall thickness of an injection molded part ranges from 2mm to 4mm (.080 inch to .160 inch). Thin wall injection molding can produce walls as thin as .05mm (.020 inch). Injection mold tooling is a very specialized profession requiring highly skilled engineers to create the injection mold tool.

 

Precision injection molding:

It is to point to the precision of molding parts and surface quality requirements are a very high process. Also, some people think, precision injection moulding is the plastic part of the size accuracy to achieve 0.01 ~ 0.001 mm injection molding process. In recent years, with electronic, medical, communications, automotive, and other industries. With the rapid development of plastic products of high precision, high-performance requirements increasing. The traditional plastic molding process has been difficult to meet the requirements of the current high standards. At the same time, injection molding is one of the most important plastic molding methods. Therefore, precision injection molding technology is getting more and more get the attention from people, make the precision injection moulding technology constantly progress, new technology constantly emerging.

 

 

Precision injection moulding for products not only has high dimensional precision, lower buckling deformation, good transfer characteristics. But also should have excellent optical performance and so on. Therefore, it is for injection molding machine, mold, injection molding technology, performance and the formula of raw material and so on all have special requirements, there are many factors which can affect the precision injection moulding.

Precision injection molding requires a high level of accuracy and consistency in the manufacturing process, which can be difficult to achieve. Here are a few reasons why precision injection molding can be challenging:

1. High tolerances: Precision injection molding requires extremely tight tolerances, often in the range of microns. Achieving these tolerances requires a high level of precision in the mold design, tooling, and manufacturing process.
2. Material properties: The properties of the plastic material being used can impact the precision of the injection molding process. Factors such as viscosity, flow rate, and shrinkage can all affect the final dimensions of the part.
3. Mold design: The design of the injection mold is critical to achieving precision in the molding process. The mold must be designed to minimize warpage, shrinkage, and other factors that can affect the final part dimensions.
4. Manufacturing process: The injection molding process itself must be carefully controlled to ensure consistent part quality. Factors such as temperature, pressure, and cooling time can all impact the final part dimensions.

Overall, precision injection molding requires a high level of expertise and attention to detail to achieve t

Custom insert molding

 

Various insert molding part use in all industry

Insert Molding (or insert moulding) in China is similar to multi-shot molding in that it results in the combination of two or more resins into a single product. Each resin is molded separately in an individual mold. And is transferred either by a robot or manually to subsequent molding operations for the additional resins. Insert molding is better suited for lower volume applications than multi-shot molding due to lower capital investment requirements. Typical applications include ‘soft-touch’ materials molded onto an enclosure (drill housing or handle) or multiple colors/materials molded together for aesthetic or functional purposes. we have broad experience in the development and manufacture of overmold products.
insert molding in China is generally much more affordable than in the West (about 50% lower in China, 30% lower in Taiwan) But of course, the whole process has to be carefully monitored to avoid disappointments.

we will devise the appropriate insert mold/mould making strategy for you. We have different ways for a complex small product and a large insert moulding tool. If you need to have real insert molded parts in hand within 2 weeks. Our prototyping team services have very cost-competitive.For the local insert molding or Export
