How to choose TPE manufacturers for smart bracelets in Dongguan

In the elastomer industry, TPE generally refers to a composite functional material modified with SEBS.

Transparent TPE is used in appliance housings, handles, grips, etc., exhibiting excellent tactile feel, non-slip and labor-saving, easy to color and process, and has a wide design space.

Transparent TPE material requires high light transmittance, which demands strict surface quality of the product, no defects such as streaks, pores, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, during the entire injection molding process, strict and even special attention must be paid to TPE raw materials, equipment, molds, and even product design.

TPE elastomer soft rubber has excellent comprehensive properties and is the most commonly used soft rubber material for two-shot injection molding, overmolding, and bi-color injection molding.

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

Transparent TPE materials have different product properties when applied in different areas. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber, which is the advantageous combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

The 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 difficult, bonding strength is low, and tactile feel is poor. If the TPE layer is too thick, on one hand the cost is high, on the other hand it is prone to shrinkage, bubbles and other defects.

Common processing methods include one-shot molding with a bi-color injection molding machine, or using a regular injection machine with an overmolding mold for two-shot injection molding. TPE overmolded products are generally handles, grips, etc. TPE soft rubber material has a special comfortable touch, and the introduction of TPE material enhances the product's grip and tactile feel.

For two-shot overmolding of nylon with a regular injection molding machine, it is recommended before overmolding,

Diene transparent TPE, diene TPE is mainly an isomer of natural rubber, so it is also called thermoplastic trans-natural rubber. Although its heat resistance and mechanical strength are not as good as rubber, due to its good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in shoemaking, sponge, optical film, and other industrial rubber products.

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

First preheat and bake the nylon part, because nylon has strong water absorption and overmolding requires high molding temperature; preheating before overmolding can remove moisture, facilitating quick hot overmolding.
