The difference between engineering plastics and ordinary plastics is quite large, especially in the performance of mechanical properties. At present, many engineering plastics have been successfully used in mechanical parts, and achieved good results. But the engineering plastic injection molding processing difficulty is quite big, is needs to pay attention to each production detail aspect.
Engineering plastic injection processing, whether it is on the injection mold or injection processing technology, or injection engineers have very harsh conditions, which are derived from engineering plastic excellent mechanical properties! For example: engineering plastic high temperature performance, since engineering plastic injection processing parts can replace metal parts, and often used in the surrounding environment is more complex, so engineering plastic must have the performance of ultra-high temperature resistance. Engineering plastic wear resistance also put forward a great demand, machinery parts and parts are mutual cooperation, mutual operation! This process can not avoid the parts before the mutual friction, so engineering plastic injection parts must be able to withstand the high intensity of friction. The above two are the most important criteria for judging whether the performance of engineering plastics is qualified. Of course, there are other criteria for judging the performance of engineering plastics, such as corrosion resistance and low temperature resistance.
In short, engineering plastic injection processing process is relatively complex, is the need to pay attention to the performance of engineering plastic itself, such as: high temperature resistance, friction resistance, corrosion resistance and so on! Also need to pay attention to the external conditions, such as: injection molding machine performance, injection mold performance can! Only when these links are in place can unqualified products of engineering plastics be avoided in the process of injection molding.
