Benefits of Guangdong TPE overmolding PC manufacturers

A bonding layer is formed at the interface between hard plastic and soft rubber,

To prevent TPE material contamination and the presence of old material or impurities in the screw and attachment recesses, especially for materials with poor thermal stability, each part should be cleaned with a screw cleaner before use and after shutdown to ensure no impurities adhere.

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

Greatly improve the overmolding adhesion between TPE soft rubber and hard plastic. False overmolding hardly involves the compatibility of the two materials; the material overmolding is achieved through mechanical force, mold and product design, surface treatment, and interlocking effect, allowing the soft and hard rubbers to bond together.

TPE overmolding injection generally adopts a two-shot injection process, that is, fixing the injection-molded hard plastic part on the overmolding mold,

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; meets environmental requirements; suitable for various transparent series products.

Transparent TPE is used in appliance casings, handles, and grips, showing very good hand feel, anti-slip and labor-saving, easy to color and process, and has a wide design space.

Then inject the TPE soft rubber onto the hard plastic 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.

Juye focuses on the R&D, production, and sales of TPE toy materials and TPE soft rubber,

Since any impurity in the TPE material can affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure the TPE material is clean. Especially, if the TPE material contains moisture, heating can cause material deterioration, so it must be dried. During injection, a drying hopper must be used for feeding.

The wall thickness of the TPE area should be as uniform as possible to achieve the best molding cycle. The transition between different wall thicknesses should be gradual to reduce fluid flow problems, such as gas marks and bubbles.
