TPR Caster

Thermoplastic elasticity TPE or TPR rubber has easy processing and molding (direct forming of injection molding machines), excellent abrasion resistance and elasticity, shock absorption, and low noise.

Usually ankle wheels such as shelves, and the wheels of the driver are made of hard plastic (such as PP, PA) and soft plastic (such as TPR, TPE, PU, EVA, TPU). The role of soft glue play a role in non -slip, shock absorption and noise reduction.

At present, the foot wheel industry, hard plastic is mainly used by cluster PP, and some of them use PA nylon. The market demand ratio of TPE and TPR in soft plastic accounts for quite large. Steps) injection molding. The first step is to injection molding hard plastic parts PP or PA; the second step, in another set of molds, first put in the moldy hard plastic parts, and fix the position, and then the soft plastic TPE, then the soft plastic TPE. TPR shoots to hard plastic parts to be covered.

The thickness of the soft glue layer of the foot wheel is usually 5 ~ 20mm, and because the material needs to have excellent abrasion resistance and elasticity (which determines the material specific formula), the thickness of the product and the formula of the material determine the TPE, TPR of TPR The cover temperature may be higher than that of the thin layer and other coverage products. It is recommended to pack glue PP. The glue and adhesive temperature is 180 ~ 220 ° C, the glue PA, and the temperature requires 240 ~ 280 ° C.
