Injection molding machine. The classification is different, more difficult to explain. The injection molding machine common crankshaft type. Consists of four steps, quick mold closing - slow mold - mold - low pressure mold four steps are open mold electromagnetic valve. Clamping speed and flow is according to the change of a system only, locking at high pressure is a switch or proximity switch limiting detection to travel. Linear compressor in the fast and slow when the mold opens quick mold closing valve (auxiliary cylinder) and the main oil cylinder piston. Slow closing, the piston closes, high pressure valve is opened, to the main oil cylinder pressure, really to the mold in place, the main oil cylinder to reach the set pressure after the completion of the mold closing action. Mold closing finish is completed by the master cylinder pressure switch detection.
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
