How to get a quote for custom thermoplastic TPE in Henan

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

Transparent TPE is used in stationery, sports equipment, etc., and has good UV resistance, chemical resistance, and easy coloring and processing characteristics.

Transparent TPE is applied to home appliance shells, handles, grips, etc., exhibiting very good tactile feel, anti-slip and labor-saving, easy to color and process, and has a wide design space.

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

PP overmolding is a plastic with very weak polarity, which is very close to the polarity of TPE based on SEBS.

Since any impurity in TPE material can affect the transparency of the product, sealing must be paid attention to 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 they must be dried. During injection molding, a drying hopper must be used for feeding.

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

Therefore, for PP overmolding, the most common TPE formula can be used directly without adding additional polar modifiers.

TPE material has good fluidity, mainly for injection molding.

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 films, and other industrial rubber products.

Thickness of 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 is difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on the one hand cost is high, and on the other hand defects such as shrinkage and bubbles are prone to occur.

TPE semi-finished toy products can be used for post-processing such as painting (spray painting, inkjet) and screen printing. Our company produces and sells TPE soft rubber materials, which can be used for injection molding to produce soft toys, simulated animal toys, plant toys, fruit toys, etc. The TPR provided has excellent color matching and oil spray characteristics, is environmentally friendly and non-toxic. Next, let's see what surprises TPE toy manufacturers bring us.
