TPE elastomer soft gel can be adjusted to the appropriate hardness according to the physical property requirements of the product (hardness range Shore 25-90A),

Since TPE transparent material requires high light transmittance, the surface quality of the material product must be strictly required, without any defects such as spots, pores, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, during the entire injection molding process, great attention and strict or even special requirements must be paid to the TPE raw materials, equipment, molds, and even product design.

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

and appropriate physical properties (such as wear resistance, scratch resistance, adhesion, melt index, etc.). It provides various possible material application solutions for different products.

TPE overmolding injection generally adopts a two-shot injection molding process, that is, fixing the injection-molded hard plastic part on the overmolding mold,

Transparent TPE is used in aspects such as appliance housings, handles, and grips. It exhibits very good hand feel, with characteristics of slip resistance and labor saving, and is easy to color and process. It also has a wide design space.

To prevent contamination of TPE raw materials and retention of old materials or impurities in the screw and attachment recesses, especially materials with poor thermal stability, it is necessary to clean all parts with screw cleaner before use and after shutdown to ensure they are free of impurities.

Then, at an appropriate temperature, the TPE soft gel is injection overmolded onto the hard plastic part, and cooled to obtain the product. The injection temperature for overmolding depends on the hard plastic material being overmolded.

Preheating the insert before overmolding helps improve bonding strength,

TPE high-transparency material has different product properties when applied in different aspects. Thermoplastic elastomer, also known as TPE material, has both the processing properties of thermoplastics and the physical properties of vulcanized rubber. This is the combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

The thickness of the TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding will be difficult, bonding strength will be low, and hand feel will be poor. If the TPE layer is too thick, on the one hand, cost is higher, and on the other hand, defects such as sink marks and bubbles are likely to occur.

Because the preheating process can improve the compatibility between the insert material and TPE. The appropriate temperature for the insert needs to be discussed and determined with the material supplier.
