How about the quotation of Jiangxi rubber TPE material

A bonding layer is formed at the interface between hard plastic and soft rubber,

The thickness of the 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 tactile feel is poor. If the TPE layer is too thick, it increases cost and easily causes defects such as shrinkage and bubbles. <\/p>

To prevent contamination of TPE raw materials and accumulation of old materials or impurities in the screw and attachment recesses (especially materials with poor thermal stability), the parts should be thoroughly cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere. <\/p>Rubber TPE material

<\/p>Greatly improves the overmolding adhesion between TPE soft rubber and hard plastic. False overmolding involves almost no compatibility between the two materials; the bonding is achieved through mechanical force, mold and product design, surface treatment, and a clamping effect that joins the soft and hard rubbers together. <\/p>

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

High-transparency TPE materials exhibit different product properties in various applications. Thermoplastic elastomers, also known as TPE materials, not only have the processing properties of thermoplastics but also the physical properties of vulcanized rubber—this is the advantageous combination of plastics and rubber. Transparent TPE is widely used in daily life and production. <\/p>

Due to high light transmittance requirements, transparent TPE demands strict surface quality of products, free from any defects such as streaks, pores, whitening, haze, black spots, discoloration, or poor gloss. Therefore, throughout the entire injection molding process, special attention and strict requirements must be given to TPE raw materials, equipment, molds, and even product design. <\/p>Rubber TPE material

<\/p>Common matching hard materials are mainly plastics, but also metals and fabrics. TPE overmolding onto fabrics is mainly used in luggage products, similar to metal overmolding, generally being false overmolding. True overmolding is often seen in two-shot injection and double-color injection, where the main material for TPE overmolding is plastic. <\/p>

When using a standard injection machine for two-shot overmolding onto nylon, it is recommended before overmolding,

To achieve the matte appearance of thermoset rubber surfaces, a rougher mold surface is required. Generally, the rough surface produced by electrical discharge machining (EDM) on the mold cavity results in an excellent workpiece appearance and easier demolding. Grinding methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to create surfaces with different gloss and appearance. <\/p>

Transparent TPE is used in applications such as appliance housings, handles, and grips, offering excellent tactile feel, anti-slip properties, labor-saving, easy coloring, and processing, along with a wide design space. <\/p>Rubber TPE material

<\/p>First preheat and bake the nylon part, because nylon has strong water absorption and overmolding requires high molding temperatures; preheating before overmolding removes moisture and facilitates rapid hot overmolding. <\/p><\/div>
