Basic Parts of a Plastic Injection Molding Machine
A Plastic injection molding machine or the injection press is used by most plastic manufacturers to produce plastic through the process of injection molding. Through this machine, the process of molding plastic products can be quickly done, which can either be in vertical or horizontal position. There are two major parts that make up the plastic injection molding machine, and these are the injection unit and the clamping.
The injection unit is part of the machine where plastic is being melted. The parts that work during the injection process are the hopper, reciprocating screw, barrel, heater and the nozzle. When the plastic granules have been added to the hopper, it will slowly go down into the barrel. It will then be pushed by the reciprocating screw through the heater. Using the appropriate temperature the plastic will then be melted and through the nozzles it will be passed to the clamping unit.
This is the part of the plastic injection molding machine where the molding process will take place. The clamping unit consists of mold cavity, mold, and the moveable platter. From the nozzles, the melted plastic will be pushed to the mold cavity where the plastic is going to be cooled down and hardened. After it has hardened, it will be transferred into the mold and to the moveable platter. The plastic will be removed from the plastic injection molding machine to clean its surface. It must be free from any excess plastic and once it is already clean it can now be stored for finished product.
The plastic injection molding machine is very useful especially to those who are involved in the plastic business. More plastic manufacturers use this machine because it will speed up the process that will result for increase in the productivity and profit.
