Where is the best TPR for sports equipment in Guangzhou?

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

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

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which gives it very different characteristics. It has the necessary aging resistance, yellowing resistance, and other properties required for producing transparent TPE, and also promotes excellent properties such as high temperature resistance and corrosion resistance. Thus, transparent TPE was created.

The material gives the product a comfortable touch, improves grip, enhances product aesthetics, and adds value.

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

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

TPE is a classic aggregation-induced emission molecule, meaning it has no fluorescence in solution but strong fluorescence in the solid state. Therefore, transparent TPE materials also have important applications in fields such as organic optoelectronics.

Then, at an appropriate temperature, the TPE soft plastic is injection-bonded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding bonding depends on the hard plastic material being overmolded.

During the molding process of TPE material, when filling the mold cavity,

The wall thickness of the TPE part should be as uniform as possible to achieve the best molding cycle. The transition between different wall thicknesses should be gradual to reduce problems caused by fluid flow, such as gas marks and bubbles.

Due to the high light transmittance required for transparent TPE, the surface quality of the material products must be strictly controlled, without any defects such as streaks, bubbles, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the entire injection molding process, strict and even special attention must be paid to the TPE raw material, equipment, mold, and even product design.

If the filling performance of the product is poor, there may be too much pressure relief, too long filling time, insufficient filling, etc., causing quality problems for the product.
