The plastics products to have already with daily life wait the aspect to acquire the extensive application at the industry, agriculture, national defense. Especially in the electronic industry then and particularly for outstanding. Electronics product that the outer shell spare parts that exaltation is mostly plastics function that request the high quantity. Type craft with product the design.
The plastics products of the type method is a lot of. Among them most of inject, die-casting to compatibly press type etc. But inject the mold, extrude, extrude roughly share type total amount of 60% above inject the type is divided in to add the material, meltdown plastics, and inject to make piece to cool off with make the piece to take off the mold to wait five steps. Certainly if make use off the electricity control. Can realize half auto or automatic homework.. Because inject the mold the type`s extensive suitable for use, exactly the basic point of departure of my this design.
