Pu castor exactly the zha to teach you with specialized production factory, not only can polyurethane elastomer and same choose plasticate, general rubber mixing, vulcanization technology molding; At the same time it also can be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting forming; Can also be made from grain, the same as the general plastic, with injection molding, extrusion, calendering, blow molding technology. Mold or injection molding parts, within the scale of hardness of must, also can be cut, grinding, drilling and other mechanical processing. Process, the diversity of the polyurethane elastomer has a very wide range of applicability, application scope expands unceasingly. Oil resistance, ozone resistance, aging resistance, radiation resistance, good low temperature resistance, good acoustic, stick relay is strong, excellent biocompatibility and blood compatibility. These strengths is polyurethane elastomer in military industry, aerospace, acoustics, biology, such as category is widely used because of it. Bi-color injection molding is now widely used in electronic products, electric tools, medical products, home appliances, toys and so on almost all of the plastic area, two-color mold making and molding and double color multi-color injection molding machine and double color injection molding raw materials research and development has a rapid development. Thermoplastic elastomer TPE | TPR rubber is easy to processing molding, Available direct injection molding) , good abrasion resistance and flexibility, good vibration and low noise performance, become the important raw materials of casters and wheels. Usually casters such as shelf wheel, cart wheels is a hard plastic (such as Such as PP, PA) And RuanSu composite forming. Hard plastic as skeleton materials of castor, have the effect of bearing, soft glue have non-slip, shock absorption and noise reduction. At present, the castor industry, hard plastic is given priority to with the copolymerization PP, also some use of PA nylon, soft plastic use TPE, TPR accounts for a considerable proportion of the market demand. Such castor processing molding, usually with 2 step ( 2 - 步骤) Injection molding. The first step to hard plastic injection molding pieces of PP or PA; The second step, in another set of mold, put good hard plastic forming parts, and fixed position, then RuanSu TPE, TPR shot stick to the position of the hard plastic parts need to be coated.
