What Is Injection Moulding?

Injection moulding forces molten polymer into a steel or aluminium mould under pressure, producing the same part thousands or millions of times over with tight repeatability. The tool is the main cost; once it exists the price per part falls sharply, which is why moulding only makes sense above a certain volume.

We build both prototype and production tools, and will tell you which one the volume actually justifies. For a few hundred parts, vacuum casting or rapid tooling is usually cheaper. Above roughly ten thousand, a hardened production tool pays for itself.

What Materials and Tolerances Does Injection Moulding Use?

Common materials are ABS, polypropylene, polycarbonate, nylon, POM, PC/ABS and TPU, with glass-filled grades where stiffness matters. Tolerances are typically held to ±0.05 mm, varying with the material’s shrinkage rate and the geometry of the part.

Send a STEP, IGS, STP, IGES or X_T file along with your expected annual volume, and we will quote tooling and per-part cost separately so you can see where the break-even sits.

Materials: production-grade ABS, PP, PC, PPA, PA66, PVC and POM. Finishing: sandblasting, blacking, painting, silk-screen and powder coating, with custom colour offered. Our factory has more than ten years of experience in injection moulding.
