Plastic injection moulding
Parts from ten grams to two kilograms. Six machines from 40 to 650 tonnes, so we don't have to make do with whatever happens to be free.
from €0.08 per piecePlastic injection moulding since 2004
The mould pays for itself over the run.
We mould plastic parts from tens of grams to two kilograms, make and maintain moulds, and assemble finished units. We'll also help you decide whether your own mould is worth it at all.

What we do
From model to finished assembly
We do the whole chain — assessing the part, the mould, moulding and assembly. That means when something goes wrong, nobody has to work out whose fault it is.
Mould making
Single and multi-cavity, with hot or cold runners. We build moulds so they can be maintained — not as a sealed black box.
from €4,200Mould maintenance and repair
Including ones made by someone else. Cleaning, replacing ejector pins, repairing the parting line. Without maintenance, a mould starts producing flash after a few hundred thousand cycles.
from €180Part design and assessment
Most parts that reach us need small changes — draft angles, even wall thickness, gate position. We'll advise you on this free of charge, before we even quote.
€0Assembly and finishing
Gluing, ultrasonic welding, pressing in inserts, packing. The customer gets a finished unit, not a bag of parts.
depending on the extentRecycling our own waste
We grind runners and rejects and feed them back into production wherever the part allows. It saves material and cost — and we'll tell you in what ratio it's done.

Work out your production run
Enter the part and the quantity. You'll see the mould price, the price per piece and, most importantly, how the mould cost spreads over the run. For small runs, the mould makes up most of the price.
Material
Without the runner. If you don't know it, estimate it from the volume — plastics have a density of around 1 g/cm³.
Part and mould complexity
The complexity of the part sets both the mould price and the cycle time.
The slider moves in the steps that are actually ordered in practice.

Materials
Which plastic for what
This is usually the first question, and most often the most important one. The wrong material only shows up in use — and by then the mould is already made.
| Material | When to choose it | Price |
|---|---|---|
| PP — polypropylenepackaging, crates, household parts | cheap, tough, takes bending | €1.60/kg |
| PE — polyethylenecontainers, films, thick-walled parts | softer, chemical-resistant | €1.50/kg |
| ABSdevice housings, visible parts | strong, can be painted and glued | €2.40/kg |
| PA6 — polyamidegears, sliding parts | wear-resistant, but absorbs moisture | €3.80/kg |
| PA6 GF30structural parts under load | glass-fibre reinforced, stiffer | €4.60/kg |
| PC — polycarbonatetransparent covers, protective parts | transparent and highly impact-resistant | €5.20/kg |
| POMprecision mechanical parts | dimensionally stable, low-friction | €4.10/kg |
| TPEseals, soft-touch grips | flexible, can be overmoulded onto a rigid part | €4.90/kg |
Machinery
Six machines from 40 to 650 tonnes
The range matters — a small part on a big machine is needlessly expensive, and a big part on a small one can't be moulded at all.
40 and 90 tonnes
Small parts up to 60 g — clips, caps, technical components. A short cycle, so large runs go quickly.
2 machines160 and 260 tonnes
Our busiest machines. Housings, packaging, crates and most of what you picture when you think of a plastic part.
2 machines400 tonnes
Larger visible parts and multi-cavity moulds. This is where production goes when you need six pieces per cycle.
1 machine650 tonnes
Our largest machine — parts up to two kilograms, crates and technical assemblies. The clamping force is enough for large surfaces too.
1 machineHow it works
Five steps from model to production run
You send a model
A STEP file, or even just a photo and dimensions. We'll assess whether the part can be moulded as drawn.
We suggest changes
There almost always are some — draft angles, even wall thickness, gate position. Without them the part would warp or show sink marks.
You get a quote
The mould price and the price per piece for your quantity. We always show you at what quantity the mould pays for itself.
We make and test the mould
Six to twelve weeks. We send the first parts for approval with an inspection report before we start the run.
We produce and store
We deliver the run in one go or in call-offs. The mould stays yours, so on your next order you only pay for the parts.
FAQ
What you ask us most often
From what quantity is it worth it?
It depends on the price of the mould. For a simple part with a €4,200 mould, it starts to pay off against 3D printing from roughly a thousand pieces, and from five thousand for more complex moulds. Under a thousand pieces, we'll tell you straight that another technology will be cheaper — and which one.
Who owns the mould?
You do, once you've paid for it. We keep it here and maintain it, but it's yours and you can take it away at any time. We put this in the contract, because in this industry it isn't a given, and it's something worth keeping an eye on.
How long does a mould last?
A steel mould handles hundreds of thousands to millions of cycles, depending on the part material — glass-filled plastics wear it out much faster. With regular maintenance, moulds can last fifteen years.
Why are you telling me the part needs redrawing?
Because most models we receive are drawn for 3D printing or machining. Injection moulding needs draft angles to release the part from the mould and an even wall thickness — otherwise the part warps as it cools or gets sink marks. We'll advise you on this free of charge.
Do you also mould recycled material?
Yes, and we grind our own runners and feed them back, usually up to 20%. We don't recommend it for visible or load-bearing parts — the properties are worse and the colour isn't consistent. We'll always tell you how much regrind is in a part.
Can we bring a mould from another company?
Yes, we do it all the time. We check that it fits our machines and that the clamping and cooling match, then run a trial. The check costs €180, and we deduct it from your first production run.
