How about the cost of TPR for sports equipment in Hunan?

On the contact surface between hard plastic and soft plastic, a bonding layer is formed,

Transparent TPE is used in stationery, sports equipment, etc., and has good UV resistance, chemical resistance, and easy coloring and processing properties.

Transparent grade includes transparent and translucent series, each with various soft hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, good tensile strength; meets environmental requirements; suitable for various transparent series products.

Greatly improve the bonding adhesion of TPE soft plastic to hard plastic. Fake overmolding hardly involves compatibility of the two materials; material bonding is achieved through mechanical force, mold and product design and surface treatment, and through embedding action, so that the soft and hard plastics can be joined together.

Overmolding of POM. Although POM has a low melting point of only 180°C.

Transparent TPE is used in household appliance shells, handles, grips, etc., and exhibits very good hand feel, with anti-slip, labor-saving, and easy coloring and processing characteristics, and also has a wide design space.

Thickness of TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand cost is higher, and on the other hand defects such as shrinkage and bubbles are prone to occur.

But due to its high crystallinity, forming a fusion layer on the overmolding surface requires high energy. At the same time, the self-lubricating property of POM is not conducive to rapid overmolding of TPE material on the surface of hard POM parts.

For secondary injection overmolding of nylon using a standard injection molding machine, it is recommended that before overmolding,

Olefinic transparent TPE has good weather resistance and ozone resistance, so it is called the fastest growing variety of TPE, and it is mainly used as the main rubber material in automotive, household appliances and other fields.

Styrenic transparent TPE is widely used in shoemaking industry, replacing most of rubber; at the same time, its use in industrial rubber products such as rubber sheets and plates is also expanding.

First, preheat and bake the nylon part. Because nylon has strong water absorption, and overmolding requires higher molding temperature; preheating before overmolding can remove moisture, facilitating rapid hot overmolding.
