Best Two-Color Injection Molding TPR in Shanxi

TPE elastomer soft gel can be adjusted to the appropriate hardness according to the product's physical property requirements (hardness range Shore 25-90A),

Transparent grades are divided into transparent and semi-transparent series, each with various softness levels; excellent transparency; smooth and soft surface; good resistance to yellowing, tear resistance, good tensile strength; environmentally friendly; suitable for various transparent series products.

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

as well as suitable physical properties (such as wear and scratch resistance, adhesion, melt index, etc.). It provides various approximate material application plans for different products.

TPE is used for overmolding and injection bonding, with TPE soft rubber as the outer covering layer,

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

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 an excellent workpiece appearance and make demolding relatively easy. Grinding methods such as steam blasting, sandblasting, shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

Commonly matching hard materials are mainly plastics, but also metals and fabrics. TPE injection bonding with fabric is mainly used in luggage products, same as with metal overmolding, generally it is false overmolding. True overmolding is mostly seen in secondary injection molding and two-color injection molding, that is, the main material for TPE overmolding injection is plastic.

Preheating the insert before overmolding helps improve bonding strength,

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

Because the preheating process can improve the compatibility between the insert material and TPE. As for the reasonable temperature of the insert, it needs to be discussed and determined with the material supplier.
