PLASTIC INDUSTRY
Injection moulding, extrusion, thermoforming — plastic processing machines depend on hydraulic precision and pneumatic reliability for every cycle.
HYDRAULICS FOR PLASTIC PROCESSING
The plastics industry covers a wide range of process technologies — injection moulding, blow moulding, extrusion, thermoforming, rotational moulding and compounding — each with distinct hydraulic and pneumatic requirements. Injection moulding machines are among the largest hydraulic consumers in the light-manufacturing sector, with clamping forces from 50 to 6,000 tonnes.
Parker hydraulic valves, pumps and cylinders, combined with our HPU manufacturing capability, serve the plastic processing sector with engineered solutions for both new machine supply and retrofit of ageing hydraulic systems. We also supply the Parker pneumatic range for plastics ancillary equipment.
WHAT WE PROVIDE
- Parker proportional and servo valves for injection velocity control
- Variable-displacement pumps for energy-efficient injection moulding hydraulics
- Custom HPU supply for large-tonnage moulding machines
- Parker pneumatics for part ejection, core pulls and robot handling
- Hydraulic cylinder manufacturing for press and forming applications
- Filtration systems to maintain ISO 4406 cleanliness in servo hydraulic circuits
