Reasons for Die Testing

Mould manufacturers often have to test the die before they leave the factory. Why do they want to test the die? In fact, this is a complicated process. Let's talk about it below.

First of all, from the point of injection moulding. Defects in moulded products are caused during the plasticizing and injection stages, but sometimes they are also related to improper die design. Possible influencing factors include: the number of cavity. The design of cold/hot runner system, the type, position and size of injection inlet, and the structure of product itself. In order to avoid the product defects caused by die design, we need to analyze the design and process parameters of the die when making the die.

Then the test results are evaluated. In order to avoid adding unnecessary cost and time in the process of modifying the die. The evaluation also includes the setting of machine process parameters. In order to make up for the deficiencies in die design, the operator may make incorrect settings without knowing it. The process of production and operation of equipment is abnormal, because the setting range of parameters needed to produce qualified products is very small. Once any minor deviation occurs in the setting of parameters, the quality of final products may exceed the allowable range of errors, and the actual production cost is often much higher than the cost of die optimization in advance.

The purpose of the die test is to find out the optimized process parameters and die design. Even if factors such as materials, machine settings or environment have changed, it is still able to maintain a stable and continuous mass production environment, not just to obtain a good sample. This is very important.
