Advantages of Hunan TPE raw material manufacturers

TPE is processed using overmolding (injection bonding), common products such as handles, grips, electronic materials, etc.

Since any impurity in TPE material can 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 the raw materials to deteriorate, so they must be dried. During injection molding, a drying hopper must be used for feeding.

Olefinic transparent TPE has good weather and ozone resistance, so it is the fastest-growing type of TPE. It is primarily used as a main rubber material in fields such as automobiles and home appliances.

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

TPE overmolding generally uses a two-shot injection molding process, where the pre-injected hard plastic part is fixed in the overmolding mold,

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

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 footwear, sponge, optical films, and other industrial rubber products.

Then, at an appropriate temperature, the soft TPE is injection bonded onto the hard plastic part, and after cooling, the product is obtained. The injection bonding temperature varies depending on the hard plastic material being overmolded.

When using a regular injection molding machine to perform two-shot overmolding on nylon, it is recommended that before overmolding,

To achieve the matte appearance of thermoset rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) will result in an excellent workpiece appearance and make demolding relatively easy. 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.

Transparent TPE materials have different product properties when applied in different aspects. Thermoplastic elastomers are also called TPE materials. 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 daily life and production.

First, preheat and bake the nylon part because nylon has strong water absorption, and overmolding requires a higher molding temperature. Preheating before overmolding can remove moisture and facilitate quick hot overmolding.
