As we all know, the selection of injection mold materials for injection molding determines its quality, and injection molding is an indispensable link in plastic molding processing, and its proportion in the total mold output is increasing year by year. According to statistics, the processing and manufacturing of injection molds It accounts for about 33% of the entire molding die, so its status in the national economy is becoming more and more important. The main factors affecting the life of plastic parts are: mold structure, mold material, mold processing quality, mold working status, product parts status, etc. In this process, the properties of the mold material itself and heat treatment play a crucial role. Processing and manufacturing of ordinary injection mold materials.
Some motorcycle accessories shells are ABS, and some are PP.
ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable
product dimensions, and good surface gloss. It is easy to paint. It can also be used for secondary processing such as surface metallization, electroplating, welding, hot pressing and bonding. It is widely used in machinery, automobiles, electronic appliances, instrumentation, textiles and construction and other industrial fields. Wide range of thermoplastic engineering plastics.
PP is currently one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water is only 0.01%, and the molecular weight is about 80,000 to 150,000. Good formability, but due to large shrinkage (1%~2.5%). Thick-walled products are easy to dent. For some parts with high dimensional accuracy, it is difficult to meet the requirements, and the surface gloss of the product is good.
In general, the performance of ABS is better than that of PP.
The company undertakes the manufacture of motorcycle accessories molds: fenders, lights, helmets and so on.
