Pneumatic Valve and Cylinder for Plastic Blowing Machine
In plastic blow molding (including PET bottle blowing), pneumatic components are critical for controlling motion and air flow at precise times during the process. These machines rely on compressed air to open/close molds,move preforms and stretch rods, deliver high-pressure blowing air to shape the plastic.Pneumatic cylinders actuate the mold halves to clamp/pre-clamp before blowing and open after forming.Stretch rods extend into the preform before blowing to stretch the plastic and then retract. Pneumatic stretch cylinders perform this action.Pneumatic valves control where and when air is sent to those cylinders and to the blow-air circuits. At plastic blowing machine there also have other pneumatic components include shock absorber,linear cylinder,pneumatic gripper,2/2 way solenoid valve,air regulator,air units,quick exhaust valve,silencer and pneumatic fittings.
