Now-a-days we are more adapted to the usage of the plastics. These plastics are available at different sizes and shapes and different thickness based on the applications used. These applications include transportations, storage, home needs, constructions, machinery parts, packaging, writing materials and electrical parts etc.. These plastic materials are made by injection molding process and blow molding process. There are many companies as an injection molding machine supplier to provide machines and spares for the plastic material manufacturing. The injection machines arrive today’s market are advanced versions which includes auto loader machines.
Those days the injection molding machine supplier, supplied manually operated machines. But today automated machines are also available. The commencement of the Auto loader machines, the feeding of the machine is made easier to feed the plastic granules into the machine via hopper. The auto loader machine is constructed with motor drive to suck the plastic granules and fed to the hopper and the control machines to control the drive. These machines have the capability of self cleaning. The stainless steel material is used to make the hopper and the mold dies and other parts of the machines. This improves the lifetime of the material, since materials are stainless, they can be cleaned easily. In modern machines, the process is automated with the help of computers.
The pre-start of the process is necessary to ensure that the outcome of the process meets the requirement by comparing first outcome’s data with the datasheet. If it satisfies, the continuous production can be proceeded. The process of plastic injection molding starts from the auto feeder , that feeds the stock into the hopper. The stock falls on the reciprocating screw, which is driven by the motor. The circular heating coil surrounds the reciprocating screw to melt the plastic granules to the temperature 220⁰ - 270⁰ C. The reciprocating screw compresses the plastic granules and takes it towards the die. The outer diameter of the screw is equal throughout its length, but its depth varies. The depth of the screw is more near hopper and it decreases as moves towards the nozzle. The molten plastic arrives near the nozzle to enter into the mold. The mold here are two parts, one is stationary mold and other is movable mold. Stationary mold is attached to the stationary supporting plate which is attached near to the nozzle and the movable mold is attached to the movable supporting plate fitted to the clamp. The clamping system can be of hydraulic, toggle or electrical clamps. The ejector pins are also attached to the movable supporting plate as to eject the plastic out from the mold. Now the movable mold and the stationary mold are compressed to mold the plastic. The reciprocating screw, pushes the molten plastic into the mold through the nozzle by hydraulic press. The molten plastic flows throughout the cavities in the mold. The cooling system is arranged in the mold in which the water acts as a coolant and it is circulated to cool the plastic. The plastic is ejected out with the sprue which is formed by injection process. This is the way the injection molding machine supplier made the plastic molding process easier by supplying modern advanced machines.
