Dongguan Two-Color Injection Molding TPR Types

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

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

Since transparent TPE requires high light transmittance, the surface quality of the material product must be strictly controlled, without any defects such as streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid attention to the TPE raw materials, equipment, mold, and even product design.

Two-color injection molding TPR

The common hard materials used in combination are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, similar to metal overmolding, generally it is false overmolding.

TPE is processed by overmolding, common products include handles, grips, electronic materials, etc.

Transparent TPE materials have different product properties when used in different applications. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastic plastics, but also has the physical properties of vulcanized rubber. This is the so-called advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's 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 bonding. If the TPE layer is too thin, injection molding is difficult, bonding strength is low, and feel is poor. If the TPE layer is too thick, on the one hand the cost is higher, on the other hand it is prone to defects such as shrinkage, bubbles, etc.

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

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 base material, while TPR is modified from SBS base material.

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is called the fastest-growing variety of TPE, and it is mainly used as a rubber material in fields such as automobiles and home appliances.

Two-color injection molding TPR

The common hard materials used in combination are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, similar to metal overmolding, generally it is false overmolding. True overmolding is more common in secondary injection molding and two-color injection molding, that is, the main material of TPE overmolding is plastic.
