Benefits of Dongguan Natural Color TPE Manufacturers

TPE material is used for overmolding, with TPE soft rubber as the soft outer layer,

TPE high transparency material has different product properties when applied in different aspects. Thermoplastic elastomer, also called TPE material, not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

Common hard materials used in cooperation are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, similar to metal overmolding, generally it is fake overmolding.

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

Styrenic transparent TPE is widely used in the footwear industry, mostly replacing rubber; at the same time, its use in industrial rubber products such as rubber sheets and rubber boards is also expanding.

TPE, TPR overmolding layer thickness. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good bonding effect. If the TPE layer is too thin, injection molding is more difficult, bonding strength is lower, and feel is worse. If the TPE layer is too thick, on the one hand cost is higher, on the other hand it is prone to shrinkage, bubbles and other defects.

Then at a suitable temperature, the TPE soft rubber is injection overmolded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding varies depending on the hard plastic material being overmolded.

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

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

To achieve the matte appearance of thermoset rubber surfaces, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) of the mold cavity will result in excellent workpiece appearance and make demolding easier. Abrasive methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

The mold temperature can be appropriately increased to 70°C, which is beneficial for bonding and also obtains a more glossy overmolding surface.
