Precautions for TPE two-color injection molding
, Shanghai Mulan two-color injection molding processing factory said that two-color injection molding can realize rapid prototyping of two raw materials or two colors. Compared with overmolding, two-color injection molding has higher dimensional accuracy and better appearance. No assembly is required, so there is very little clearance. Therefore, it is favored by many cross-border e-commerce companies, brand companies, and trading companies. So, how to do two-color injection molding of TPE material, and what are the precautions?
Shanghai Mulan Two-color Injection Molding Factory focuses on the one-stop finished product customization business of small household electrical appliances.

For TPE two-color injection molding, it summarizes the following What time is it:
1. During the two-color injection molding process, the mold flow channel is relatively long, so the raw materials must have good thermal stability and processing fluidity to prevent long-term stay in the flow channel during the two-color injection molding process, causing degradation and silver filaments. and other poor appearance;
2. According to different product requirements, two-color injection molding processing needs to be tested for corrosion resistance, hydrolysis resistance, aging resistance, flame retardancy, and mildew resistance;
3. Pay attention to the hardness requirements after two-color injection molding. The hardness standard of plastic parts is determined by the physical characteristics of TPE required by customers;
4. During the two-color injection molding process, the raw materials for the two-color injection molding process must have good compatibility in order to ensure the quality of the two-color injection molding plastic parts.
The above is a brief introduction of the 'TPE Two-color Injection Molding Precautions' by Shanghai Mulan Two-color Injection Molding Factory.
