Browse used injection molding machinery for sale from top manufacturers.

Buying a used injection molding machine starts with matching tonnage and shot size to your part. As a rule of thumb, plan for 2-5 tons of clamp force per square inch of projected part area — higher with engineering resins, glass-filled materials, or thick walls. Verify tie-bar spacing and platen dimensions accommodate your mold, and confirm the injection unit's shot capacity is at least 30-80% of the barrel volume for stable processing.

Next, evaluate the technology fit. All-electric injection molding machines (Fanuc Roboshot, Nissei NEX, Sumitomo SE-EV) excel at precision medical, optical, and connector molding where repeatability and energy efficiency matter. Hydraulic plastic injection molding machines from Engel, Arburg, and Milacron remain the best value for high-tonnage and heavy automotive work. Hybrids split the difference with electric injection plus hydraulic clamp — a strong fit for high-cavitation packaging.

Finally, inspect the machine itself. Check screw and barrel wear, platen parallelism, tie-bar stretch, hydraulic cylinder condition, clamp mechanism, and control vintage. Modern Keba, B&R, and OEM controls offer SPC, recipe management, and OPC-UA networking — older injection moulding machines may run well mechanically but lack data capabilities required by automotive and medical OEMs. Meadoworks documents every plastic injection molding machine in our inventory and can arrange inspection under power before purchase.

Injection molding equipment is the most widely used plastic molding process worldwide, producing everything from medical syringes to automotive bumpers. Meadoworks customers use our used injection molding machines across automotive (interior trim, under-hood, bumpers, lighting), medical (devices, packaging, single-use disposables), packaging (closures, thinwall containers, PET preforms), consumer products (housings, appliances, toys), and electronics (connectors, housings, optics).

When you contact Meadoworks for an injection molding machine, share your part weight, projected area, material (PP, PE, ABS, PC, nylon, PEEK, etc.), required cavitation, and production volume. Our team — including AMEA-certified appraisers with 50+ years in plastics — will recommend the right tonnage, screw geometry, and brand for your application from our current plastic injection molding machine inventory.

Choosing the right used injection molding machine (also called a plastic injection machine, injection mold machine, or plastic molding machine) requires careful evaluation of several key specifications. Clamp tonnage is the primary sizing metric — you'll need 2 to 5 tons per square inch of projected part area, depending on material and wall thickness. Shot size and plasticizing capacity must match your part weight and cycle time requirements. Consider tie bar spacing and platen dimensions to ensure your mold fits properly, with room for water lines and ejector access.

The choice between hydraulic, all-electric, and hybrid injection molding machines depends on your application. All-electric machines (also called servo-electric injection machines) from manufacturers like Fanuc, Nissei, and Sumitomo Demag offer superior precision, faster dry cycles, and 30-50% energy savings — ideal for cleanroom medical and precision electronic components. Hydraulic plastic injection molding machines from Engel, Arburg, and Milacron provide higher clamp forces at lower acquisition costs, making them the workhorse choice for automotive and large-part production. Hybrid machines combine the best of both, with electric injection units and hydraulic clamps.

Control system vintage matters — modern Keba, B&R, and proprietary OEM controls offer networked monitoring, SPC integration, and recipe management. Older injection moulding machines may still run well mechanically but lack the data capabilities required by automotive and medical OEMs. Always check machine hours, shot counter, and maintenance records when evaluating any used plastic moulding machine.

How much does a used injection molding machine cost? Plastic injection molding machine prices vary based on tonnage, brand, age, condition, and technology type. Here are general used injection molding machine price ranges:

Small tonnage machines (under 200 tons): $15,000-$75,000. Popular for desktop injection molding, benchtop injection molding, small injection molding, and prototyping applications. Brands like Boy, Nissei, Arburg, and Wittmann Battenfeld are common in this range.

Mid-range machines (200-500 tons): $40,000-$150,000. The workhorse range for general-purpose molding of consumer products, packaging, and electronics. Engel, Arburg, Krauss Maffei, and Milacron are popular in this tonnage.

Large machines (500-1000 tons): $75,000-$300,000. Used for automotive bumpers, large containers, and industrial parts. Two-platen machines from Engel, KraussMaffei, and Haitian dominate this segment.

Very large machines (1000+ tons): $150,000-$500,000+. Required for automotive dashboards, pallets, and large industrial components.

All-electric injection molding machines command 20-40% premiums over hydraulic. Second hand injection moulding machines from premium brands like Engel, Arburg, and Krauss Maffei hold value best. Contact Meadoworks at 800-323-0307 for injection molding machine prices on specific models.
