Temperature Control Requirements and Mould Maintenance in Injection Moulding

The requirement of temperature in injection processing is very strict. Controlling the temperature of injection processing is an important factor that determines the eligibility of injection processing products. In view of the injection processing temperature, today I would like to talk about the matters needing attention in injection processing temperature. The following three points have a direct impact on the injection processing temperature: 1.
1. Nozzle temperature: nozzle temperature should not be too low, otherwise it will cause premature solidification […]

Which engineering plastics are used for automobile plastic parts?

With the rise of automobile lightweight, more and more automobile plastic parts are used. Developed countries regard the amount of plastics used in automobiles as an important symbol to measure the level of automobile design and manufacturing. German automobile plastics account for 15% of the total material. In recent years, China’s automotive industry has developed rapidly. At present, the annual output of automobiles exceeds 4 million. Referring to the trend of foreign countries, the annual use of modified plastics […]

Seven problems in injection molding process of transparent ABS plastic materials should be paid attention to

In order to reduce internal stress and surface quality defects, the following seven problems should be paid attention to in the injection molding process of transparent ABS plastic materials (including the requirements of injection molding machine)
1. Special screw with separate temperature control nozzle should be used.
2. Injection temperature: under the premise that plastic resin does not decompose, it is advisable to use a higher injection temperature.
3. Injection pressure: generally higher, in order to overcome the melt viscosity of large […]

Main characteristics of plastics for automobiles

Polymer automotive materials have many advantages that traditional materials did not have in the past. Mainly manifested in light weight, good appearance decoration effect, a variety of practical application functions, good physical and chemical properties, easy processing and shaping, energy saving, sustainable use and other aspects. The main characteristics of polymer automotive materials are as follows.
 

Light weight

 
One of the most outstanding advantages of polymer automotive materials is that they have the characteristics of light weight and high strength. Because […]

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 […]
