What Is Micro Moulding?

18/07/2026

Micro moulding is injection moulding at the small end of the scale: tiny parts and fine features where precision is everything. Moulding at a Tiny Scale Micro moulding produces very small plastic components, or parts with extremely fine and intricate features. Think small clips, gears, connectors, medical micro-components and precision detail parts. At this scale, tiny variations have a big effect, so tool precision and process control matter even more than usual. Why It's Specialised Filling a tiny cavity with fine features, then ejecting the delicate part without damage, takes carefully designed tooling and a tightly controlled process. The margins for error are very small. What Is It Used For? Micro moulding is common in medical devices, electronics, and detailed products such as jewellery components, anywhere small, precise plastic parts are needed. Repeatability Is the Point The whole purpose of micro moulding is to reproduce fine detail consistently, part after part. That's achieved through precision tooling and validated process control.
