Working Principle, Structure and different types of Plastic Molding Machines

From the shape or clamping direction, we can classify the plastic injection molding machine into horizontal type, vertical type and angle type plastic molding machine.

From the function, we can classify the machine into standard plastic molding machine, high speed plastic molding machine, servo motor plastic injection molding machine, variable pump plastic molding machine, etc.

From the material difference, we can classify the PET plastic injection molding machine, PVC plastic injection molding machine, PA plastic molding machine, PC plastic molding machine, Normal material plastic molding machine, Bakelite plastic molding machine, BMC plastic molding machine, etc.

According to the driver difference, plastic molding machine usually can be classified into hydraulic plastic molding machine, electrical plastic molding machine, and hydro plastic molding machine.

According to the injection system, there are with single color plastic molding machine, double color plastic molding machine, multi color plastic molding machine.

Plastic Molding Machine Structure

The plastic molding machine standard structure mainly including the below parts: injection parts, clamping parts, plastic molding machine body, hydraulic system, heating system, control system, material loader system. You can refer to the below photos.



Plastic Molding Machine Working Principle

The main working principle of plastic molding machine is to use the plastic thermal physical properties. First, we auto loader the plastic material into the barrel, which is surround by heating elements melting the plastic. In the barrel which is assembled with servo motor screw. The plastic melt will flow up the screw and under the heating condition get tight and move forward to the screw head. At the same time, due to the plastic reacting force, the screw will step back. So at the screw head, it formed a plastic melt saving space to finish its plasticizing process. At the same time, under the injection hydraulic cylinder force, the screws will injection the plasticizing melt into the plastic mould through the nozzle. The plastic melt will remain in the mould cavity through the holding pressure, cooling, process, and then formed into solid shape ejected out of the mould. So the plastic molding machine main recycle process including: quantitative feeding-plasticizing-injection-molding the shape-pick up the piece, then close the mould to the 2nd recycle process.
