In today’s living environment, most things are closely related to injection molded products. We can see injection molded products everywhere in our daily lives, such as soft-bristled toothbrushes, phone cases, Bluetooth handles, and the seat cushions and pillow cores we use. All of these are produced through injection molding. This has already become closely integrated with our daily lives. However, there are still many key points to pay attention to. Below, we will explain the key points of TPE coating:

The injection molded TPE raw material with coating is subject to higher standards due to the fact that coating is a secondary injection process. Therefore, there are more critical points to pay attention to. Let’s summarize the following aspects:

1. The production processing temperature during injection molding. The general temperature range is 170-220. Since the secondary injection molding with coating requires completely adhering the product, the temperature is relatively higher. This is also to ensure better product quality.

2. The shrinkage rate of the stamping mold. Since the secondary injection molding with coating encapsulates the already formed product from the unformed raw material, the product will expand and contract due to high temperature. Therefore, it is necessary to calculate the shrinkage rate of the product to ensure the product specifications.

3. The material of the product. Since only the same material can completely integrate, the first step is to clearly define the material of the product. Clearly define the material and select the corresponding TPE material. Since TPE is a customized raw material, different recipes can be formulated based on different materials.

4. The fluidity of the TPE material. Since coating has higher requirements for material fluidity, only a material with good fluidity can completely cover the product’s surface. This also prevents uneven surface leveling and uneven distribution.

5. The touch sensation of the TPE material. Since coating is designed to make the product have a better touch sensation, the selection of material is to choose materials with better touch sensation. As TPE is a customized raw material, its soft strength can be designed according to the customer’s requirements.
