Analysis and solution to the causes of bubbles and voids in TPE injection molded products

TPE bubbles and voids mostly refer to the voids generated inside the thick wall of the molded part. The outer casing of the molded part is condensed and solidified by injection molding, and the amount of the melt is insufficient relative to the entire part, thereby generating vacuum holes, which generally occur. In places where the product is thick and at the sprue. It is called a bubble or a void. Generally speaking, if a bubble is found at the moment […]

Causes of dents in mould processing of automotive plastic parts

Plastic mould processing as a processing technology, after its production or completion, there will be some bad situation. How to solve this problem?
 
The causes of dents are as follows:
1) Insufficient cooling of the mould and insufficient cooling time will cause serious deformation.
 
2) Insufficient internal pressure of the mould will also occur.
 
3) The thickness of each part of the product is different. In this case, the overall treatment method is to reduce the barrel temperature and mould temperature, force cooling in the […]

10 Factors Affecting The Quality Of Injection Molds

Mold manufacturing is a complicated process. From the steps of design, processing, assembly, debugging, etc., to the final use, there are mainly 10 factors that affect the quality of the mold throughout the lifetime.
1.Steel is the decisive factor in the quality of the mold, and choosing the right steel is the top priority. 
The criteria for choosing steel are:
①Requirements for injection molding materials
Different plastics should use different steels, such as requirements for high polishing, corrosion resistance, etc.z
②Price
If the steel is […]

What are the effects of wall thickness of plastic products on quality

The wall thickness of the plastic parts processed by injection moulding has a great influence on the quality. When the wall thickness is too small and the flow resistance is too large, it is difficult for large and complex plastic parts to fill the cavity. The minimum size of the wall thickness processed by plastic parts should meet the following requirements:
 

It has enough strength and stiffness.

 

It can withstand the shock and vibration of demoulding mechanism when demoulding.

 

Can withstand the […]

What Is A Short Shot In Injection Molding?

A short shot is the incomplete filling of a mold cavity which results in the production of an incomplete part.
If a part short shots, the plastic does not fill the cavity. The flow freezes off before the flow paths have completely filled.
To ensure the finished part is of good quality, the part must also be adequately packed with plastic. Therefore the question to ask is not only, “Will the part fill?” but also, “Can a good quality part be made?”
Causes

Flow […]

How to maintain automotive plastic parts?

Automotive plastic parts are used more and more widely. Automotive plastic parts are not only cheap, but also environmentally friendly, beautiful, convenient and durable. Nowadays more and more automobile metal parts are replaced by plastic parts. In order to ensure the normal operation of various parts, the maintenance and maintenance of automobile plastic parts are also very important.
 
Maintenance methods of automotive plastic parts:
 

Inspection: Deformation and damage of automotive plastic parts are determined by inspection.

 

Fastening: Fastening is an important maintenance […]

Suggestions On The Maintenance Of Injection Molds

Compared with other moulds, the structure of injection moulds is more complex and precise , the operation and maintenance of the product requirements are higher, so in the entire production process, the use of positive solutions and careful maintenance, maintenance to maintain the normal production of enterprises, improve the efficiency of enterprises, has a very important significance.
 

Select the appropriate molding equipment, determine the reasonable process conditions, if the injection molding machine is too small to meet the requirements, too […]

How long does injection molding take?

The main determinant is the total number of products that customers need to produce. It takes about the same time to produce a product. Multiply the time to produce a product by the total amount of production the customer needs to produce to figure out how long it takes.
 
Material and machine preparation time should also be taken into account before formal production. The preparation time of the machine is very short, because the equipment of the injection moulding factory […]

Welding Line In Plastic Injection Molding Process

Weld Lines
The flowing defects on product surface or the linear defects that are caused when melt fronts meet each other after splitting.
Weld lines refer to the lines that occur on a plastic product surface when the cold slug melts. In areas of mold cavity where the molten plastic meets inserts or holes, areas with inconsistent flow speed/flow interruptions, where multiple flows meet or when jetting happens during mold filling, linear weld marks tend to occur due to imperfect bonding.
