How to Choose Henan TPE Two-Color Injection Molding

TPE is processed by overmolding, commonly used for products such as handles, grips, electronic materials, etc.

Due to the high light transmittance required for transparent TPE, strict surface quality requirements are necessary, without any defects such as streaks, bubbles, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, throughout the entire injection molding process, great attention and strict even special requirements must be paid to TPE raw materials, equipment, molds, and even product design.<\/p>

To prevent contamination of TPE raw materials and the retention of old materials or impurities in the screw and accessory recesses, especially materials with poor thermal stability, the screw cleaner should be used to clean all parts before use and after shutdown, ensuring they are free of impurities.<\/p>TPE Two-Color Injection Molding

<\/p>The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value.<\/p>

TPE overmolding generally uses a two-shot injection molding process, where the molded rigid plastic part is fixed in the overmolding mold,

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. This is the advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily production and life.<\/p>

Transparent TPE, specifically, is a thermoplastic elastomer, while TPR is translated from English, strictly speaking called thermoplastic rubber. This is the most basic difference. TPE is generally modified from SEBS basic materials, while TPR is modified from SBS basic materials.<\/p>TPE Two-Color Injection Molding

<\/p>Then at a suitable temperature, the TPE soft rubber is injection overmolded onto the hard plastic part and cooled to obtain the product. The injection temperature for overmolding varies depending on the hard plastic material being overmolded.<\/p>

TPE is used for overmolding, with TPE soft rubber as the soft outer covering layer,

Since any impurities in the TPE material can affect the transparency of the product, it is necessary to pay attention to sealing during storage, transportation, and feeding to ensure the TPE raw materials are clean. Especially if the TPE raw materials contain moisture, heating can cause the material to deteriorate, so they must be dried. During injection molding, a drying hopper must be used for feeding.<\/p>

Transparent TPE is used in home appliance casings, handles, and grips, etc. It offers excellent hand feel, is anti-slip and saves effort, and is easy to color and process. It also has a wide design space.<\/p>TPE Two-Color Injection Molding

<\/p>Common rigid materials to be bonded are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used for luggage products, similar to metal overmolding, which is generally false overmolding. True overmolding is more common in two-shot injection molding and two-color injection molding, i.e., the main material for TPE overmolding is plastic.<\/p><\/div>
