Injection molding machine from China

The machine and the mould must fit each other, and a 200-ton quote does not tell you whether your mould fits between its tie-bars or whether its screw can fill your part.

What you are actually comparing.

Two quotes, one machine name

What hides inside the price

What "ton" means in the quote

Clamping force holds the mould shut during injection. Spec sheets often state it in kilonewtons and round it to tons. Ask for the kN figure and compare quotes on that.

Screw option A, B or C

One clamp size is sold with three screw diameters. A larger screw gives a bigger shot at lower injection pressure; a smaller screw suits thin walls. Different screws mean different machines.

Tie-bar spacing, mould height and opening stroke

The mould must pass between the four tie-bars, close within the mould height range, and open far enough to eject the part. These differ between machines of the same tonnage.

Drive: fixed pump, servo pump or all-electric

A fixed hydraulic pump runs all the time. A servo pump turns only when needed. All-electric suits clean rooms and precise parts. Ask for measured kWh per kg on a stated part, not a percentage saving.

Screw and barrel material

Glass-filled nylon, flame-retardant grades and PVC wear or corrode a standard nitrided screw. For these, ask for a bimetallic screw and barrel in the quote.

Controller and interfaces

Ask for the controller brand, heating and hot-runner zones, core-pull and valve-gate sequences, and a EUROMAP 67 robot interface.

Mould included or not

A machine quote rarely includes the mould. If one supplier quotes both, ask for separate lines and warranties, and who is responsible for part tolerance.

Decode the model code.

Most Chinese model codes carry the clamping force, in tons or kilonewtons. A code with 200 or 200T is about 2,000 kN; 1980 means 1,980 kN. The code says nothing about the screw option.

1 tonne-force = 9.81 kN, so 2,000 kN / 9.81 = about 204 tonnes-force. Sheets that treat 10 kN as 1 ton put 200 ton and 2,000 kN in the same class.
Shot size follows screw area: (55 / 45) x (55 / 45) = 1.49, so a 55 mm screw gives about 1.5 times the shot of a 45 mm screw on the same machine.
Pressure falls by the same factor: 220 MPa x (45 / 55) x (45 / 55) = 147 MPa, close to the 150 MPa listed for the 55 mm screw.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

The part: drawing, part weight, wall thickness and projected area. Projected area times cavity pressure gives the clamping force needed.
The polymer grade, including glass fibre or other fillers, and whether it is flame retardant.
Your mould's outer dimensions, closed height and required opening stroke, so tie-bar spacing and mould height can be checked first.
Cavities, hot or cold runner, and how many hot-runner, core-pull and valve-gate zones the controller must drive.
Target cycle time and yearly volume, which decide whether a servo pump or all-electric drive repays its price.
Supply voltage, frequency and electrical capacity, and floor loading at the machine position.
Automation: robot, dryer, chiller, mould temperature controller. Say which belong in the quote.

Turn the claim into a demonstration.

Require this	A pass looks like
Run your mould, or one of similar size and weight, on the machine you will receive, for a counted number of cycles agreed in advance.	All cycles complete at the agreed cycle time with no manual intervention and no alarm, on a signed log.
Weigh parts from the start, middle and end of the run, and measure the critical dimensions.	Part weight stays inside the spread agreed before the test, and every critical dimension is in tolerance.
Install the mould, cycle it through full opening stroke, and test front gate, rear gate and emergency stops.	The mould clears the tie-bars and ejects at full stroke. Every guard stops clamp movement when opened.

The documents that must arrive with it.

EU Declaration of Conformity naming the Machinery Directive 2006/42/EC, or the Machinery Regulation (EU) 2023/1230 for delivery from 20 January 2027, plus 2014/35/EU and 2014/30/EU.
The risk assessment and the list of standards applied. Ask whether EN ISO 20430, the safety standard for injection moulding machines, was used.
Manual in the language of the country of use, with hydraulic and electrical diagrams.
Platen drawings: tie-bar spacing, locating ring size, ejector pattern and mould mounting holes.
Spare parts list with seals, heater bands, thermocouples and check ring.

The one people forget. The platen drawing. Buyers approve the machine, then find their moulds need a different locating ring or ejector pattern. Get it before shipment so adapter plates are ready.

When this is the wrong machine.

Buy something else if

Named, not hedged

Your part is hollow, such as a bottle, canister or tank.

A blow molding machine, or a PET bottle blowing machine for drinks bottles.

You need a precise machine soon and your volumes are modest.

A used European or Japanese machine of the right tonnage from a dealer, with service history. After freight, duty and commissioning it can cost less than a new import.

Where the numbers come from.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Listings · 12Twelve marketplace listings for 200-ton injection molding machines, checked September 2026, advertised FOB asking prices from US$5,000 to US$70,200. Most did not state the screw option, drive type or tie-bar spacing. These are asking prices, not landed cost.
Listings · 3Three manufacturer spec sheets for machines of about 2,000 kN, checked September 2026, listed tie-bar spacing of 480 x 480, 500 x 470 and 530 x 530 mm, and maximum mould height from 480 to 550 mm.
Listings · 3The same three sheets each offered 45, 50 and 55 mm screws. On one, shot weight rose from 314 g to 470 g of polystyrene while injection pressure fell from 220 to 150 MPa.
Arithmetic(55 / 45) squared = 1.49 and 470 / 314 = 1.50, so shot weight follows screw area. 220 MPa x (45 / 55) squared = 147 MPa, close to the listed 150 MPa.
GAPGAP - no supplier quotations logged for this machine yet. Three to five quotations for one configuration, for example a 2,000 kN servo-pump machine with the B screw, would give a real price spread.

Straight answers

Questions buyers ask about this machine.

What is the best injection molding machine from China?+

The one that fits your mould and fills your part at a stable weight. Choose the clamp by projected area and the screw by shot weight, then check tie-bar spacing and mould height. Compare prices last.

Chinese vs European injection molding machine: which should I buy?+

For general parts in standard polymers, a Chinese servo-pump machine can do the job. For medical, optical or very thin-wall parts, European and Japanese machines usually offer better repeatability and local service. Ask each supplier for the part-weight spread over a counted run.

What should a factory audit of an injection molding machine maker check?+

Whether platens and tie-bars are machined in-house, where screws and barrels come from, and whether machines are tested with real moulds before shipment. Ask to see a completed test record for a recent machine.

What CE documentation does an injection molding machine need?+

An EU Declaration of Conformity naming the model and serial number, the technical file with the risk assessment, and a manual in your language. A CE mark on a brochure proves nothing. Ask for these before any deposit.

Who is the EU importer of an injection molding machine?+

Buying directly from outside the EU normally makes you the importer. Your name and address go on the machine or its documents, and you check the conformity documents exist and match it. Delivery after 19 January 2027 means Regulation (EU) 2023/1230 applies.
