About Used Hydraulic Injection Molding Machines
Hydraulic plastic injection molding machines (also known as hydraulic plastic moulding machines) remain the workhorse of the plastics industry. Using hydraulic pumps and cylinders to power clamp, injection, and ejection movements, these machines offer proven reliability, lower purchase prices compared to all-electric alternatives, and availability in very large tonnages up to 6,000+ tons.
When evaluating a used hydraulic injection molding machine, inspect the hydraulic system carefully — check for leaks, oil condition, pump pressure, and valve response. Modern variable-displacement pump systems offer significant energy savings over older fixed-pump designs. Servo-hydraulic systems provide improved precision while maintaining the cost advantages of hydraulic technology.

Frequently Asked Questions
How much does a used hydraulic injection molding machine cost?
Used hydraulic plastic injection molding machines are typically the most affordable option in the used market. Small (50-200 tons): $10,000-$60,000. Medium (200-500 tons): $30,000-$120,000. Large (500-1000 tons): $50,000-$250,000. Very large (1000+ tons): $100,000-$500,000+. Prices are 20-40% below comparable all-electric models.
What is a hydraulic plastic moulding machine?
A hydraulic plastic moulding machine (also spelled molding) uses hydraulic pumps and cylinders to generate the force needed for clamping the mold, injecting molten plastic, and ejecting finished parts. Hydraulic oil is pressurized by pumps and directed through valves to hydraulic cylinders. This is the original and most common type of injection molding machine technology.
