Guangdong Natural Color TPE Supplier Price

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

TPE transparent grade includes transparent and semi-transparent series, each with various hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, tensile strength; environmentally friendly; suitable for various transparent series products.

Transparent TPE is applied to household appliance casings, handles, grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and features easy coloring and processing. It also offers a wide design space.

The already injection-molded rigid plastic parts are fixed onto the overmolding mold, and then TPE soft plastic is injection overmolded onto the rigid parts at an appropriate temperature, and then cooled to obtain the product. The injection temperature for overmolding depends on the rigid material being overmolded.

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

The transparent grade includes transparent and semi-transparent series, each with various hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, tensile strength; environmentally friendly; suitable for various transparent series products.

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

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

When using a standard injection molding machine for two-shot overmolding on nylon, it is recommended before overmolding,

The wall thickness of the TPE part 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 air marks and bubbles.

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

First, preheat and bake the nylon parts because nylon has strong water absorption, and overmolding requires a high molding temperature; preheating before overmolding removes moisture and facilitates quick hot overmolding.
