The following five major elements are indispensable in the processing of double-shot moulding:
1.Mold evaluation and product analysis
Before mold design, mold evaluation and product analysis is a must including the appearance, size and shape to avoid unnecessary complication for two-color mold design.
An good mold design should not only meet the requirement of customers, but also save costs, reduce the difficulty of processing, shorten the processing time for customers. To achieve this, we must not only fully digest the requirements of customers, but also have an full understanding of injection machine, mold structure, processing technology and processing capabilities of mold factory itself.
Material selection is very important for double-shot moulding. It should meet the requirements of wear resistance, toughness, fatigue fracture performance, high temperature performance, cold and heat fatigue resistance, corrosion resistance etc.
4.Parts processing and assembly
In addition to reasonable design and material selection, the accuracy of double-shot moulding is also crucial in the subsequent processing and assembly. Therefore, in order to ensure precision processing of mold, high-precision advanced processing equipment and experienced technicians are must.
In order to avoid wasting time and trouble during mass production, it is necessary to adjust and control various processing conditions after mold has been assembled to find the best temperature and pressure conditions. In the trial process, it is necessary to follow reasonable operation steps and record the useful technical parameters in the test process to facilitate mass production of the product.
