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

The advantages of plastic medical products

 

Plastic applications and advantages in the medical industry

Plastic application in the medical industry：

Medical equipment related to the pharmaceutical industries, machinery, electronics, plastics, etc., wherein the
plastic rapid development of medical devices. Since the 1930s people first used synthetic polymer materials.
Since celluloid film is formed as an artificial kidney dialysis membrane used in clinical success. Polymer
materials are gradually replacing traditional inorganic materials such as metal, glass, ceramic, apatite stone
for the preparation of medical devices. The advantages of plastic medical products.
 
 
This is the reason:

(1)Polymer material having good mechanical properties and chemical stability, more suitable for medical use;

(2) Polymer material rich source of inexpensive. Disposable medical supplies made for avoiding the problem of
sterilization. And secondary infection due to the high cost of traditional materials and products have caused
repeated use;
 
(3) Having a plastic or modified more easily get a good histocompatibility and blood compatibility of products;
 
(4) Plastic low production costs, for a variety of molding methods, ease of processing into complex shapes. And the development of new medical products.
 

Plastics in the medical industry advantages:

 
The advantages of plastic medical products. From medicines and pharmaceutical packaging. The needle tube, hose, disposable surgical instruments. And other medical equipment can be seen in the presence of plastic instruments.
 
The disposable medical device market demand potential is why so big, its main advantage is the following aspects:

1, Lightweight, effort, will help reduce fatigue caused by surgery doctors for a long time.

2, Toughness is good, strong anti-permeability, durability, some plastics can also be used normally at high temperatures.

3, Transparent, medical procedures can be better observed, especially during surgery.

4, Easy to shape, for the production of a variety of shapes, complex medical equipment, and supplies. And
simply use the low-cost production process. High-temperature sterilization using disinfectant or corrosion does
not occur or the color change phenomenon.

5, Compared to metals and other raw materials, low cost. More suitable for the production of disposable
consumables. After sterilization as packaging materials, help to reduce the risk of infection.

6, Compared with ceramic or glass and other fragile materials. The use of more safety, especially as packaging materials.
 
With the increase in the proportion of population growth and an aging population. The demand for plastic medical equipment continued to expand, particularly into the human body equipment. The use of medical equipment from a single to diversified development. The volume size is shrinking. Now equipment can replace conventional multiple pieces of equipment. Because of the many outstanding advantages of plastic medical equipment. The pharmaceutical industry in the future course of development, it's market share and influence will grow.

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
