Fujian TPR material manufacturer price

TPE is processed by overmolding injection bonding. Common products include handles, grips, electronic materials, etc.

The transparent grade comes in transparent and translucent series, each with various softness and hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, tensile strength; environmentally friendly; suitable for all kinds of transparent series products.

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

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

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

Since any impurity in the TPE material can affect the transparency of the product, attention must be paid 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 dry hopper must be used for feeding.

Because TPE transparent material requires high light transmittance, the surface quality of the material product must be strictly controlled, 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 requirements must be placed on TPE raw materials, equipment, molds, and even product design.

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

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

The wall thickness of the TPE material section 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.

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

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