Injection molding machine manufacturers build machines for plastic processing that range from compact 7-tonne units to 2,000-tonne giants.
They come as hydraulic, all-electric and hybrid servo models, and they make everything from bottle caps and syringes to car bumpers and pipe fittings.
The right choice depends on your clamping force, shot size, material and production volume.
Injection molding machine manufacturers design and build the plastic injection moulding machine itself. That covers the injection unit (screw and barrel), the clamping unit, the hydraulic or servo drive, and the PLC controller. The manufacturer does not make your mould or your plastic parts. It makes the machine that turns thermoplastic granules into those parts.
The 4-step process works like this:
Clamp the mould → Inject melted plastic → Cool the part → Eject it.
A well-built machine repeats this thousands of times with a steady cycle time and very little part-to-part variation.
Manufacturers build several designs. Each suits a different job.
Machine type | How it works | Best for |
Hydraulic | Oil pressure drives movement. | Heavy parts, high clamping force, general moulding. |
All-electric | Servo motors drive every movement. | Medical, electronics, precision parts, clean rooms. |
Hybrid servo | Servo motor plus hydraulics. | Good balance of energy saving and power. |
Horizontal | The mould opens sideways. | Most standard production. |
Vertical | The mould opens up and down. | Insert moulding, over-moulding, small footprint. |
Something to Consider →
All-electric and hybrid machines generally consume less energy than older hydraulic ones when calculated on long runs.
However, hydraulic machines remain a popular choice due to lower upfront costs and minimal maintenance.
Tonnage is the clamping force that holds the mould shut during the injection cycle. Too little and you get flash (excess plastic leaking at the mould edges). Too much and you pay for capacity you never use.
The Standard Approach
Based on the resin, you can increase the part’s projected area (in square inches) by 2 to 5 tons and add a safety margin. Don’t forget to confirm with your mould designer or machine supplier.
Size | Typical clamping force | Typical products |
Micro/small | Under 100 tons | Caps, connectors, small gears, medical parts |
Medium | 100 to 500 tons | Household goods, containers, appliance parts |
Large | 500 to 1,000 tons | Crates, furniture, automotive interiors |
Extra large | 1,000+ tons | Bumpers, dashboards, large bins, pallets |
Advance Plastic Machinery lists 170+ injection moulding machines ready for delivery, from 7 tons to 2,000 tons, including imported Japanese used machines from brands such as Mitsubishi, Toshiba, JSW, Sumitomo, Niigata and Nissei. It also offers new machines, auxiliaries like hopper dryers, grinders and hybrid servo systems, and finance options.
Choosing among injection moulding machine manufacturers comes down to a few clear decisions: the machine type (hydraulic, electric or hybrid), the right clamping force for your mould, and a partner who stands behind the machine after delivery. A well-matched machine pays back through steady quality, lower energy bills and fewer stoppages.

Japanese and European makers are known for precision and durability, while Chinese and Indian makers are strong on value and local service. When you shortlist injection moulding machine manufacturers or brands, choose by application, support and budget.
Yes, you can buy a used injection machine if it is well maintained, inspected and test-run before purchase. This can cut upfront costs, especially for start-ups and general-purpose production.
PP, PE, ABS, PVC, PC, PA (nylon) and PET are the common materials used in injection moulding. Some need dried material, which is why hopper dryers matter.
A good machine can run for many years, often decades with regular servicing. Lifespan depends on maintenance, operating hours and usage conditions.
Yes, as long as the mould fits the machine’s platen size, tie-bar spacing, clamping force and shot capacity.
An injection moulding machine melts plastic granules, injects the melt into a closed steel mould under pressure, and ejects a finished part once it cools.
A vertical plastic injection machine is an injection moulding machine whose clamping unit opens and closes up and down, so the mould sits flat and
