How to make high quality injection parts

Although in the plastic injection mold technology, to produce high gloss, high aesthetic requirements, not subject to the stress generated in the molding process, with high stability of parts, as well as reliable filling of thin-walled materials, are facing great challenges. However, hot / cold forming is being rapidly accepted in automotive interiors and many other consumer applications requiring high surface aesthetics. Let’s take a look at the production process plan of high-quality injection parts with high gloss;
Change of […]

Discoloration of common problems in plastic injection molding

Discoloration refers to the inconsistency between the surface color of the formed parts and the required color. Discoloration may be caused by a variety of reasons, including injection molding machine, plastic mold, injection process and raw materials.
(1) Injection molding machine
① The equipment is not clean and needs cleaning. Dust or powder deposited in the barrel contaminates and discolors the material;
② Temperature control failure caused by temperature controller or heating system failure;
③ There are obstacles in the barrel, which lead […]

What are the specific functions of inserts in the processing of injection mold

In the process of injection mold, the application of mold insert is very extensive. It can be seen not only in the front mold and the back mold, but also in the slider and the inclined roof. So what kind of role does the insert play in the processing of injection mold?
1. Facilitate the processing and maintenance of injection mold
The manufacturing process of injection mold is very complex. In the process of processing, some parts with complex structure and […]

“5S” management of plastic mould factory

5S “is the basic method of site management, and” sorting, rectifying, cleaning and literacy “.
Sorting out: distinguish between the things to be used and the things not to be used in the workplace.
Rectification: put the necessary things in order according to the specified location and method, clear the quantity and mark clearly.
Cleaning: clean up the workplace and prevent pollution.
Cleaning: institutionalize, standardize and maintain the results of the above 3S implementation.
Accomplishment: cultivate civilized and polite habits, act according to regulations, […]

Material selection in injection molding of medical industry

The choice of injection molding materials is very popular. Even if the requirements for all medical grade materials narrow the selection range, the number of materials meeting these key specifications is still large. But what conditions should the selected material meet in order to meet the requirements of medical grade materials?
Durability – many of the plastics used in injection molding have excellent strength and durability to resist harsh environments, vibrations and blunt forces without cracking.
Heat resistance – many injection […]

Design of Wall thickness

Product structure is the key to the mould cost factors, to implement a function has a variety of different design, different design decision mold manufacturing method, determine the price of the mould is different also, some structure only requires us to pay attention to some design principles, maybe you can save a lot of cost, you can view our design guidelines to learn.
If we ignore the wall thickness of the product, the appearance problems caused by the uneven wall […]

How to improve the ejector pin in the injection molding process

In the injection molding process, what causes the ejector pin?
There are many reasons for ejector pin in injection molding products, such as too high mold temperature, too high injection pressure, too large pressure holding, unreasonable thimble distribution, insufficient demoulding force and so on.
How to improve the ejector pin in the injection molding process?
1. Avoid over injection of plastic melt.
2. Reduce injection pressure and holding pressure.
3. Reduce the injection speed, optimize the feed system design, and achieve good filling.
4. Properly […]
