Extrusion Blow Molding Machine

详情

Extrusion blow molding is a process for directly manufacturing hollow plastic bottles/containers by using the standard extruder screw and barrel assembly to plasticise the polymer. This molted mass (called parison) is a tube-like piece of plastic with a hole in one end in which compressed air can pass through. After dropping from extruder, this hollow tube is captured by closing it into a water-cooled mold as well as knife cut the parison at the top. When the molds are closed and moved sideways to second position where air is pumped with approximately **0 PSI pressure through the top or the neck of the container, inflating it into the shape of the hollow bottle, container, or any mold shape (same like as if one were blowing up a balloon). When the hot plastic is blown up and touches the walls of the mold, the cooling process of parison starts. After the parison has cooled and hardened, the mold is opened and finished product is ejected.

HITECH PLASTICS ENGINEERING offers the complete extrusion blow solution in cooperation with the world-known brand LESHAN which had focused on blow molding technology for more than *0 years. In addition, HITECH PLASTICS ENGINEERING also offers all auxiliary machinery required in extrusion blow process. Auxiliary equipment that used in extrusion blow process include cooled water machine (for controlling heat temperature of overall system), crusher (for crushing trimming waste), feeding system (for convey the trimming waste to crusher or convey material to hopper of blow molding machine) and air compressor (for compressed air).

LESHAN offers the U series (linear guide rail) blow molding machine which can work with PE, PP, EVA and so on. These blow molding machines are equipped with exclusive screw and die head which is suitable for different requirements. SIEMENS HMI (TP**0) touch screen and computer make the operation of blow molding machine more convenient. Effective energy consumption is ensured by the permanent magnet brushless motor which is adopted by the LESHAN blow molding machine. U series blow molding machine has unique characteristics such as optimized design of the hydraulic circuit, scissors toggle clamping system, central force clamping plate, strong clamping force and use of imported components in the pneumatic system, hydraulic system and electrical control components. Platform lifting function makes the machine suitable for different height of mold and different blow molding process requirement.
