How about Zhejiang two-color injection molding TPR?

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

Since TPE transparent material requires high light transmittance, the surface quality of the material product must be strictly controlled, without any defects such as streaks, pores, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, great attention and strict or even special requirements must be paid to TPE raw materials, equipment, molds, and even product design.

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the recesses of screws and attachments, especially materials with poor thermal stability, all parts should be cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere.

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

TPE is used in overmolding injection, with TPE soft rubber as the outer covering layer,

Transparent TPE materials have different product properties when applied in different aspects. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastic plastics, but also the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastic and rubber, and transparent TPE is widely used in people's life and production.

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

Common matching hard materials are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, similar to overmolding with metal, generally false overmolding. True overmolding is more common in secondary injection molding and two-color injection molding, i.e., the main material for TPE overmolding is plastic.

TPE as raw material. TPE material manufacturers have environmental protection, non-toxicity, good elasticity, and smooth surface. In addition,

Olefinic transparent TPE has good weather resistance and ozone resistance, so it is called the fastest-growing variety in TPE. It is mainly used as a major rubber material in fields such as automotive and home appliances.

To achieve the matte appearance of thermosetting rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) of the cavity will result in 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 create surfaces with different gloss and appearance.

The surface is not easy to attract dust, has good thermal conductivity, excellent anti-fouling performance, and passes skin safety and non-sensitization tests to meet the characteristics that silicone cannot meet, making the appearance more high-end and exquisite. TPE is positioned as the preferred high-end raw material in the industry.
