Are the prices for natural TPE processing in Dongguan favorable?

TPE elastomer soft rubber is used for two-shot injection molding and overmolding.

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

Due to the good slip resistance and elastic touch of TPE materials, they can improve the touch feel of products and enhance grip.

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

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

In order to achieve the matte appearance of thermoset rubber surfaces, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) of the cavity will result in an excellent workpiece appearance and make demolding relatively easy. Abrasive methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

Common matching rigid materials 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 mostly seen in two-shot injection molding and two-color injection molding, where the main material for TPE overmolding is plastic.

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

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 thermoplastics, but also has the physical properties of vulcanized rubber. This is the so-called combination of advantages of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

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 major rubber material in fields such as automotive and home appliances.

If the filling performance of the product is poor, there will be excessive pressure reduction, too long filling time, unqualified filling, etc., resulting in product quality issues.
