Why the injection molding become so popular in manufacture

Definitely, if one of the spare parts on your machine or equipment does not function properly, you will need to order a new one for a replacement. However, if your equipment is custom-made, you will have to produce or purchase a customized spare part. But, this process will take a long time, depending on how difficult the part is manufactured and what kind of materials are used. However, if you already have a plastic injection mold which produces parts, it will be quite […]

Prospects of Plastic Mould Industry

Plastic mould industry is a traditional industry in China. It started earlier and developed more and more mature. At the same time, it has also grown a number of potential small and medium-sized enterprises. The future of plastic mould industry is considerable, but the technology level is still far from that of foreign countries.
Plastic mold is a tool for plastic processing industry and plastic forming machine, which gives plastic products complete configuration and precise size. Because there are many […]

The injection molding production process

The injection molding process is usually comprised of 6 steps:

The clamping: An injection machine contains 3 parts – the injection mold, the clamp and the injection unit, among which, the clamping unit keeps the mold at a certain pressure, so as to ensure the consistency of the outputs.

A mold is usually made up of 2 parts.

The injection unit: It refers to the part where the plastic pellets are fed into the hopper located at the top end of the […]

Characteristics of Precision Injection Moulding

Precision injection moulding requires high technology and high quality, and requires professional precision moulding equipment to injection moulding. What are the characteristics of precision injection moulding?

(1) The dimension accuracy of the parts is high and the tolerance range is small. That is to say, the dimension deviation of precise plastic parts with high precision dimension limit will be less than 0.03mm, and some even small to micron level. The detection tool depends on the projector.
(2) High repetition accuracy of […]

3 ways to find a good plastic injection mold manufacturer in China

When a new product is designed well, many customers are going to find a plastic injection mold manufacturer for a trial order. At this point, selecting a proper plastic mold manufacturer is very important. As a professional manufacturer who specialize in mold making , here we have some advises for your reference.
(1)Better choice for cooperation in mold manufacturer
Currently, there is a diversity of mold manufacturers available in the China market, including foreign-funded companies, Taiwan invested firms, Hong Kong enterprises, […]

Advantages of Automotive Plastic Parts

Automotive plastic parts are light in weight, and have many colors, beautiful, good weight loss effect, reduce the weight of the body itself. It can be recycled and recycled many times. In automobile recycling, most of the metal products do not have recycling value, because they are too old and rusty. Plastic products, because of its regeneration characteristics, can basically be melted after secondary processing, and will not produce any harm.

Advantages of automotive plastic parts:
Plastic products have the advantages […]

Design Flow of Plastic Mould

The structure of plastic parts is ever-changing, but not every plastic part can be opened smoothly, so it is most important to analyze the product data reasonably before opening, which can avoid a lot of trouble.

First, at the beginning, we must define the design requirements of plastic parts. We should consider the feasibility and economy of injection moulding process from the aspects of plastic varieties, shape, dimension accuracy and surface roughness of products. When necessary, we should carefully discuss […]

Reasons and Solutions for Shrinkage Rate of Injection Mold

Shrinkage rate of injection mold is always an important part in the development of injection mold. This ring has a tremendous impact on the size of the plastic. After the structure of the die is determined, all parts of the die can be designed in detail, that is, the size of the template and parts, the size of the cavity and core, etc. At this time, the main design parameters such as shrinkage of materials will be involved. Therefore, […]

Why Plastic Material need baked Before Injection Moulding?

In the process of injection moulding, the moisture content of material should be within a relatively low range to ensure the normal injection moulding and the normal physical properties of product materials. The water content of injection material is too high. First, there will be bad appearance of silver wire on the surface. Secondly, water vapor in the material will cause bubble holes in the product, which will affect the strength. Thirdly, if the moisture content is high, the […]

Why It Is Expensive to Customize A Set of Plastic Injection Moulds?

Plastic injection moulding is an efficient and mass production method, which can realize one-time moulding of plastic products with complex shapes. In the mould industry, in order to produce injection moulds with high precision, high quality and complex surface, we must use advanced computer aided design and manufacturing software to compile reasonable processing procedures, which is the necessary process to ensure the processing quality.

In addition to the above reasons, the reasons for the higher price of injection moulds are […]
