TPE uses overmolding process,

The thickness of TPE, TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm ensures good adhesion. If the TPE layer is too thin, injection molding becomes difficult, adhesion strength is low, and the feel is poor. If the TPE layer is too thick, on one hand the cost is higher, on the other hand it is prone to defects such as shrinkage, bubbles, etc.

Since any impurity 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 material is 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.

Common products such as handles, grips, electronic materials, etc. The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value.

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

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

Because TPE transparent materials require high transmittance, the surface quality of the material products must be strict, without any defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special attention must be paid to the TPE raw materials, equipment, molds, and even product design.

The common hard materials used with TPE are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products. Like overmolding with metal, it is usually false overmolding. True overmolding is more common in two-shot injection and bi-color injection, where the main material for TPE overmolding is plastic.

Preheating the insert before overmolding helps improve adhesion strength,

TPE high-transparency 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 so-called advantageous combination of plastic and rubber. Transparent TPE is widely used in people's life and production.

Transparent TPE is used in home appliance casings, handles, grips, etc. It exhibits very good touch, is anti-slip and labor-saving, and is easy to color and process. It also has a very wide design space.

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