How to choose a Tianjin TPE transparent material manufacturer

TPE overmolding generally uses a two-shot injection molding process,

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

To achieve the matte appearance of thermoset rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) of the mold cavity will result in an excellent workpiece appearance and make demolding relatively simple. Grinding 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.

The already molded (injection molded) hard plastic part is fixed onto the overmolding mold, and then at a suitable temperature, the TPE soft rubber is injection molded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding depends on the hard plastic material being overmolded.

TPE overmolding generally uses a two-shot injection molding process, i.e., fixing the already injection molded hard plastic part onto the overmolding mold,

Transparent grades are divided into transparent and translucent series, each with multiple hardness ranges; excellent transparency; smooth and soft surface; good anti-yellowing properties, tear resistance, good tensile strength; environmentally friendly; suitable for various transparent series products.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which makes its characteristics very different. It has the necessary anti-aging and anti-yellowing properties required for producing transparent TPE, and also contributes to excellent properties such as high temperature resistance and corrosion resistance. Only then was transparent TPE manufactured.

Then at a suitable temperature, the TPE soft rubber is injection molded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding depends on the hard plastic material being overmolded.

When using a regular injection molding machine to perform two-shot overmolding on nylon, it is recommended before overmolding,

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

TPE transparent materials require high light transmittance, which inevitably demands strict surface quality of the material products, without any defects such as streaks, air bubbles, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, great attention and strict or even special requirements must be placed on TPE raw materials, equipment, molds, and even product design.

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