Best TPR material manufacturer in Henan?

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

The wall thickness of the TPE material area 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.

Fix the hard plastic part that has been injection molded onto the overmolding mold, then at a suitable temperature, inject and bond the TPE soft rubber onto the hard part, and cool to obtain the product. The overmolding injection temperature depends on the hard plastic material being overmolded.

TPE is processed by overmolding, commonly used products such as handles, grips, electronic materials, etc.

Transparent TPE is used in appliance housings, handles, grips, etc. It provides excellent hand feel, is slip-resistant and labor-saving, and is easy to color and process. It also offers a broad design space.

Olefin-based transparent TPE has good weather resistance and ozone resistance, making it the fastest-growing variety of TPE. It is mainly used as a primary rubber material in automotive, home appliance and other fields.

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value. The products are mostly exported to developed countries and regions such as the United States, Japan, and the European Union.

The overmolding temperature is generally controlled at 30-50°C, but for some TPE grades with strong crystallinity,

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which makes its properties very different. It has the necessary aging resistance, yellowing resistance and other properties required for producing transparent TPE, and also contributes to excellent high temperature and corrosion resistance. Thus transparent TPE is produced.

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

The mold temperature can be appropriately increased to 70°C, which is beneficial for bonding and also results in a glossier overmolding surface.
