How about Henan TPE two-color injection molding?

TPE uses overmolding injection processing. Common products include handles, grips, electronic materials, etc.

Transparent TPE materials have different product properties in different applications. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics, but also the physical properties of vulcanized rubber, which is the advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the recesses of the screw and attachments, especially materials with poor thermal stability, it is necessary to clean each part with screw cleaner before use and after shutdown, so that no impurities adhere.

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value. Most products are exported to developed countries and regions such as the United States, Japan, and the European Union.

TPE high-transparency material has different product properties in different applications. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber, which is the advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

To achieve the matte appearance of thermoset rubber surfaces, a rougher mold surface is required. Generally speaking, the rough surface produced by electric discharge machining (EDM) of the cavity will result in an excellent workpiece appearance and make demolding relatively easy. Grinding methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

The temperature in the feeding zone should be set quite low to prevent blockage of the feed port and allow entrained air to escape.

Transparent TPE, specifically thermoplastic elastomer, while TPR is translated from English, strictly speaking it is called thermoplastic rubber. This is the basic difference. TPE is generally modified from SEBS base material, while TPR is modified from SBS base material.

Since any impurity in the TPE material may affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure the TPE raw materials are clean. Especially if the TPE raw material contains moisture, heating will cause the material to deteriorate, so it must be dried. During injection molding, a drying hopper must be used for feeding.

To change the mixing state, the temperature in the transition zone should be set above the melting point of the masterbatch, so that the mixing state is changed when using the masterbatch. The temperature near the nozzle should be set close to the required melting temperature.
