CUSTOM PLASTIC INJECTION
INJECTION MOULDS
IN BELGIUM —
YOUR IDEAS INTO REALITY

Because you get a single point of contact, from 3D file to delivered part. Design and feasibility analysis are carried out with our partner LGR Design Studio, mould manufacturing is coordinated with our partners, and injection runs on our three presses of 50, 100 and 250 tonnes in Ath. Large volumes are produced by our Polish partner, ISO 9001 certified. On projects with a volume commitment, we co-invest up to 50% of the mould.

Plastic injection moulding is the most widely used industrial process for manufacturing parts in series. Plastic pellets (PP, ABS, PC, PA, POM...) are heated until molten (200-320°C), then injected under high pressure (up to 2,000 bar) into a hardened steel mould. The material solidifies and takes the exact shape of the cavity. Precision of ±0.05mm, from 100 to several million units.

An injection moulding press has three parts: the hopper (pellets), the plasticising unit (screw in a heated barrel), and the clamping unit, which holds the mould closed with a force ranging from tens to hundreds of tonnes depending on the machine. The screw pushes molten material into the closed mould, water circuits cool the part, the mould opens and the part is ejected. Cycle of 15 seconds to 2 minutes.

Mould price depends on part geometry, cavity count and target volume: each project is quoted individually, not from a price list. To optimise: simplify the geometry, choose the cavity count based on your real volume, and have the design analysed before machining. Mould manufacturing is coordinated with our partners, with European production available on request. And on projects with a volume commitment, we finance up to 50% of the mould.

Design for Manufacturing follows precise rules: uniform wall thickness of 1.5-3mm, draft angles of 1-2°, fillet radii of at least 0.5mm, ribs at 60% of the adjacent wall. Free DfM analysis is provided by our partner LGR Design Studio before mould launch. Send your 3D file for feedback within 48 hours.

Five levers: 1) Optimise the design to reduce material and cycle time. 2) Choose the right material: a standard PP often replaces a far more expensive technical polymer when the specification allows it. 3) Match the cavity count to the volume: at high volume, multi-cavity moulds cut the part cost sharply. 4) Automate post-injection operations. 5) Produce in Europe: our prices are generally 20 to 30% below French mouldmakers.
