Where to find good two-color injection molding TPR in Dongguan

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

Since any impurity in TPE material may affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure the cleanliness of TPE raw materials. Especially if TPE raw materials contain moisture, heating will cause deterioration, so drying is essential. During injection molding, a dry hopper must be used for feeding.

Transparent TPE is used in appliance housings, handles, grips, etc. It exhibits very good hand feel, non-slip and labor-saving features, easy coloring and processing, and has a wide design space.

Two-color injection molding TPR

Fix the already injection-molded hard plastic part on the overmolding mold, then inject and bond the TPE soft plastic onto the hard plastic part at an appropriate temperature, and cool to obtain the product. The injection temperature for overmolding depends on the hard plastic material being overmolded.

TPE overmolding, as the name suggests, is the process of overmolding TPE soft material onto other materials.

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

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

Two-color injection molding TPR

Common processing methods include one-shot forming using a two-color injection molding machine, or using a conventional injection molding machine with an overmolding mold for two-shot injection molding. TPE overmolded products are generally handles, grips, and similar items. TPE soft material has a special comfortable touch, and the introduction of TPE improves the grip and tactile feel of the product.

The overmolding temperature is generally controlled at 30-50°C, but for some highly crystalline TPE grades,

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its applications in industrial rubber products such as rubber sheets and plates are also expanding.

TPE high-transparency material has different product properties in different applications. Thermoplastic elastomer, also known as 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 plastics and rubber. Transparent TPE is widely used in people's daily life and production.

The mold temperature can be appropriately increased to 70°C, which is beneficial for bonding and can result in a more glossy overmolded surface.
