Shanxi Natural Color TPE Processing Cost

TPE uses overmolding injection processing,

Due to the high light transmittance required for transparent TPE materials, the surface quality of the material products must be strict, without any defects such as streaks, pores, whitening, halo, 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 materials, equipment, molds, and even product design.

Thickness of 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 is more difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand the cost is higher, and on the other hand it is prone to defects such as shrinkage and bubbles.

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

TPE overmolding, as the name implies, is to overmold TPE soft material onto other materials.

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its use in industrial rubber products such as rubber sheets and plates is also expanding.

Transparent TPE materials have different product properties in different applications. Thermoplastic elastomer, also known as TPE, not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber. This is the advantageous combination of plastic and rubber, and transparent TPE is widely used in people's daily life and production.

Natural Color TPE Processing

Commonly used processing methods include one-step molding with a two-color injection molding machine, or using a general injection molding machine with an overmolding mold for two-step injection molding. TPE overmolded products are generally handles, grips, etc. TPE soft material has a special comfortable touch, and the introduction of TPE material improves the grip and tactile feel of the product.

Preheating the insert before overmolding helps improve adhesion strength,

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

Olefinic transparent TPE has good weather resistance and ozone resistance, so it is the fastest-growing variety of TPE. It is mainly used as a primary rubber material in fields such as automotive and home appliances.

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