The extrusion blow molding machine is a machine for blowing thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into high-grade packaging boxes and frames of various shapes. The operation procedure is also very simple. It only needs to turn on the heating switch to turn on the heating time, adjust the heating time, and select the appropriate electric heating time of the electric wood mold heating piece according to the actual packaging condition.
China blow molding machine factory tell you that blow molding is also called thermoplastic molding. This molding process mainly uses the vacuum blowing force generated by the vacuum pump to soften the soft plastic PVC, PET, PETG, APTT, PP, PE, PS, etc. The sheet is blown into a vacuum cover, a blow tray, a bulb, and the like in various shapes. The main structure is composed of feeding, pulling, upper and lower electric heating furnace, lower brake, multi-function adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, releasing and equipped with vacuum device; Pneumatic device is the main power source, and its pull-tab and feed piece adopt electric, speed reducer, time relay, intermediate relay, travel switch and other electrical components to form a fully automatic control system.
The requirements of the blow molding machine for the control system are to ensure easy operation, high precision of mechanical action and temperature control, short production time, and as much as possible to save mechanical power consumption under the same production conditions.
