How much does plastic injection moulding cost? This isn't a simple figure, but rather the outcome of choices in design, material, volume, and quality requirements. Tooling costs, unit price, engineering costs, and quality assurance together determine the total project investment. In this article, we'll explain all the cost components so you can make a realistic estimate for your situation.

Maternity costs are the largest one-off investment

The mould is in virtually every Injection moulding project the largest cost factor. A single mould for a simple part starts at around 3,000 to 5,000 euros. A complex multi-mould for a precision part can cost 80,000 euros or more.

What determines these costs? The complexity of the mould, the number of cavities, the choice of tool steel and the required surface finish. A mould with sliders or core pulls for undercuts will cost more than a simple two-part mould. The same applies to moulds made of hardened steel for abrasive materials such as fibreglass-reinforced PA.

At Eurotechniek 2026, we assess early in the design phase whether the mould geometry is optimal for production. A small adjustment in the design can significantly reduce mould costs without compromising the function of the part.

Plaster costs fall at higher volumes

The unit price per injection-moulded part is directly dependent on the production volume. For a batch of 500 units, the cost per unit is high because the mould investment is spread over few units. At 50,000 units, this distribution decreases significantly and the cycle time becomes the dominant factor.

For example: a medium-sized polypropylene housing costs approximately 1.20 euros per unit for 1,000 pieces, excluding the mould. For 20,000 pieces, that same unit price drops to 0.18 euros, purely due to economies of scale in cycle time, setup, and material purchasing.

Cycle time, the number of seconds per injection moulding cycle, determines how many parts a machine produces per hour. Complex geometries, thick wall thicknesses or materials with long cooling times increase the cycle time and therefore the unit cost. Thin-walled designs with uniform wall thickness cool down faster and directly reduce the cycle time.

Material costs vary greatly per plastic.

In addition to mould and machine costs, material costs are also factored in. Standard polymers such as PP and PE cost between €1.20 and €2.00 per kilogram. Engineering plastics like PA66 GF30 or POM range from €3.00 to €6.00 per kilogram. High-performance materials such as PEEK can cost €80 per kilogram or more.

The material consumption per part depends on the product weight and the percentage lost as sprue and runner. In a cold runner system, this material is lost or must be regranulated. A hot runner system virtually eliminates this loss but increases the mould investment by €2,000 to €15,000, depending on the configuration.

Eurotechniek 2026 advises based on the total project. Sometimes a hot runner system is profitable with as few as 10,000 units per year, and sometimes only at higher volumes. We make that decision concrete, not based on gut feeling.

Design and engineering costs are not a side issue

Anyone wanting to bring a new component into injection moulding requires engineering. This begins with a DFM analysis (design for manufacturability), where the design is assessed for processability. Draft angles, wall thicknesses, ribs, gate locations, and surface specifications collectively determine whether a mould produces smoothly and reproducibly.

A DFM analysis costs on average between €500 and €2,000, depending on the complexity. This investment will pay for itself. A design that is not optimised for injection moulding leads to quality problems in the T1 samples and correction rounds on the mould, each of which can cost between €500 and €5,000.

In addition to DFM, there are costs for 3D modelling, mould drawings and potentially simulation software such as Moldflow. For complex parts with tight tolerances, Eurotechniek 2026 transparently includes these costs in the quote, so you won't encounter any surprises with the first production run.

Quality assurance and certification affect the price

Not every injection moulded product requires the same quality standards. A decorative part has different requirements than a functional, safety-critical part for the automotive or medical sectors. Quality assurance takes time and money, but is not optional if the application demands it.

For medical or automotive applications, PPAP documents, FAI reports, or material certificates are mandatory. This requires inspection reports, process validations, and traceability of material batches. These requirements increase the administrative and operational costs per project.

A practical example: a precision component for a medical device required full IQ/OQ/PQ validation of the injection moulding process. That validation cost €8,000 as a one-off expense, in addition to the mould investment. This was acceptable to the customer because the component had to be produced in a certified cleanroom environment. Eurotechniek 2026 guides these types of processes from quotation to certified series production.

Calculating total project costs is done like this

The total cost of an injection mould project consists of four components: mould costs, engineering, part costs, and quality costs. This sum is the investment for the project, not just the price per part.

A realistic estimate for a new injection moulding project looks as follows. A single P20 steel mould for a technical part costs €12,000. The DFM analysis and mould drawing cost €1,500. The unit price at 5,000 pieces per year in PA66 is €0.65. After two years of production, the total costs including mould and engineering are €20,500 for 10,000 pieces, or €2.05 per piece fully accounted for.

Those who only look at the piece price miss the complete picture. Those who compare the total project costs against the lifespan of the mould and the expected volume make better decisions about material, design, and production strategy. Eurotechniek 2026 compiles that calculation together with the customer, so that the quote aligns with the business case.

Frequently asked questions about the cost of injection moulding

What is the minimum batch size for which injection moulding is profitable?

This depends on the mould costs and the unit price of an alternative such as 3D printing or milling. If a milled version of a part costs €15 and the injection mould costs €8,000 with a unit price of €0.80, then the break-even point is around 570 units. Above that quantity, injection moulding is cheaper per unit. Eurotechniek 2026 performs this calculation on request, so you can make choices based on facts, not assumptions.

Can I bring an existing mould from another supplier?

Yes, that is possible in principle. We assess the mould for condition, steel type, cooling circuit, and compatibility with our machines. Sometimes adjustments are necessary, and sometimes the mould can be used directly. If you bring a mould that is not optimally designed for the material or the desired cycle time, we will discuss this beforehand. We avoid hidden costs due to a poor mould condition by conducting an honest assessment at the start of the process.

How quickly can I have a mould built and start production?

The lead time for mould construction averages between six and twelve weeks, depending on complexity. Simple single cavity moulds sometimes achieve six weeks. Complex multi-cavity moulds with hot runners require ten to twelve weeks or more. Following the initial T1 samples, a correction round follows if necessary, after which series production commences. Plan your lead time generously and discuss the schedule during the quotation phase with Eurotechniek 2026, so that the production date and delivery time align.

Injection moulding begins with a fair cost estimate

The price of injection moulding isn't a number you look up; it's a result of choices. Choices in design, material, volume, and quality requirements. Those who make these choices early in the process with the right technical guidance will pay less and get more out of the project.
