Plastic Blow molding machines for the production of 5L hdpe

Introduction

We are one of the leading names of the industry known for manufacturing superior quality Extrusion Blow Moulding Machine. We are manufacturing this machine using optimum quality raw material with a combination of sophisticated technology.

We are having the finest experts associated with us taking charge of the manufacturing process. Each machine manufactured by us need to pass through strict quality check process under various parameters before reaching the hands of the customers using the same.

We are offering this machine in wide range with various specifications at an affordable price range. The design is compact and consumes less power.

DIE HEAD

Head mode: the continuous extrusion head is designed with material center coming-in type and removing the plastic melting line on the product surface, easily for material or color change, saving the time & material cost with speedy operation.

EXTRUSION SYSTEM

Gradient mixing type with high-speed energy saving design, gradually changed screw with same distance and different deep. Material of screw: High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥800,brittleness≤2. Material of barrel: High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥900,brittleness≤2.

HYDRAULIC SYSTEM

The main hydraulic system is mainly composed of motor, pump, pressure regulating valve block, reversing valve blocks, cylinders and oil chillers. It controls platens open & close, carriage up & down, extrusion system up & down, blow pin actions, or even spinning cut and so on.

ELECTRICAL CONTROL

The electrical control system is composed of operation panel, temperature control module, PLC, input & output module, proportion board, contactors, voltage stabilized source, air swtiches, mid relays, proximity switches, inverter and motors. The operation panel contains power switch, touch screen, alarm, hot cutter knob, auto cycle button, emergency stop button, action reversion button, extruding speed button.

MECHANICAL STRUCTURE

Clamping unit is composed of front & back platens, clamping seat, carriage seat, mould stroking & clamping hydraulic cylinders, synchronizing mechanism, with the structure of nether crank design. Platen movements open & close, carriage up & down is assisted with linear guide rails & ball bearing sliders to increase action smoothness and position precision. The end positions & slow speed positions are controlled by proximity switches or transducers.

AIR & WATER SUPPLY

The pneumatic system contains air cylinder, air valves, air filters, air tubes, fast plugs and so on, for controlling the actions of head inner blowing, blow pin blowing, auto-deflashing, or pushing in & out for some special moulds. The necessary air pressure is 0.6~0.8 Mpa, air consumption is 0.8~1.0 M3/min. The water system contains water distributing blocks, ball valves, tubes, connectors and so on, for chilling the screw & barrel, hard gear box, blowing units and moulds. The necessary water pressure is 0.2~0.4 Mpa, water consumption is 4500L/hour.
