HZU-75 full automatic hydraulic extrusion blow moulding machine, a wide variety of materials can be used for the machine, which are suitable for producing multi-type products for mass production. The clamping system is a high-precision single-station linear guide, extrusion system using a hard gear reducer and inverter imported from Japan. The die head system adopts central-incoming extrusion die made of special steel, imported hydraulic valve and seal parts with proportional control valve. The control system consists of PLC and Human-machine interface imported from siemens Germany; siemens touch screen, PLC an automatic temperature control module and imported electrical parts. This can deploy tri- die heads, four-die heads and six die heads. Especially it can be used for washing, commodity, and parts of vehicle, toys and some related products for mass production. This machine has a high efficiency so as to produce more plastic products.
