How to choose the mold steel for mirror polishing? May 20, 2019
To make high quality mirror polishing on mold (cavity and core inserts, same as below), the requirement of mold surface polishing of mold is high, because this is the most important loop of mold manufacturing. The surface with roughness and corrugated grain is an abnormal phenomena in mirror polishing of molds. Generally, it is the the mold steel material, the polishing method, or the inject...

Correct gate type and location for plastic mold Jun 10, 2019
When we design a mould , to chosing the gate type and location is very important. It will caused processing problem , even the quanlity of plastic products. Mould design engineer shouldn't only calculate for plastic products , but also should especially pay attention to the design for gate. They must chose the correct gate type , the numbers of gate and location . The gate type a...
Short Shot Injection Molding Jun 14, 2019
Insufficient injection is also called short shot. Short shot is the phenomenon of partly incomplete at the end of the material flow, or a part of the cavity filled with dissatisfaction, especially the thin wall area or the end area of the the runner when injection molding. When the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavi...

What to consider when designing the plastic mold? Jul 19, 2019
There are some points that should be noticed when plastic mould design: 1.The draft angle should be designed to be more than one degree. 2. It is suitable to select the direction of the projection surface of the plastic part as the direction of forming pressure, which is convenient for the material to fill the cavity, but it is not suitable for the part with high dimensional accuracy and the axis ...

The short shot checkpoints Jun 28, 2019
The short shot checkpoints As mentioned that, when the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavity, it is called the short shot injection molding. We analyse the reasons of short shot. So today let’s discuss how to improve the insufficient injection. Here lists short shot checkpoints: 1) Improper control of process conditi...

There are undercuts around products'4 corner,should we make lifter or slider? Jul 08, 2019
As we know, During mold designing, If the product has inner undercut, we usually make lifter, If has outside undercut, we will make slider, But If it has undercut around the 4 corner, and couldn't be forced demoulding, what should we do? As below picture, should we make lifter or slider? 1. Design Analysis If so, first we will think about to make lifter, but after analyze, If make lifter the...

What is 'Catch hook and thin-wall' of plastic mold products? Sep 18, 2019
What is 'Catch hook and thin-wall' of plastic mold products? 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe. Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall...
