What is micro injection molding?
When we talk about molded plastic parts that weigh a fraction of a gram, we're probably pushing the limits of micro-molding, which is many times smaller than mini-molding. To define micro injection molding it is good to keep in mind that the tolerances for micro parts are between 50µm and 5µm. It's no surprise that such precision parts are widely used in the medical and dental industries - many surgical instruments in these fields are invasive.
Molding such micro-parts requires complex tooling and mold-processing methods, as well as bespoke configurations of precision plastic injection machines, because shrinkage management is even more challenging for micro-parts. On the other hand, the basic principle of precision injection molding is the same as in conventional injection molding - liquefied plastic is injected into the injection mold.

We do our best to guide our customers through the jungle of material selection. We have 10 years of experience to share with you. Material selection is one of the first things to consider when designing a new micro part, as all major design constraints will continually relate to the plastic chosen. Please use our material guide for the right choice of plastic and whether the optimal result can be achieved in plastic injection molding.
Micro tooling - Mold machining
Precision parts are made with precision moulds. We design micro parts and their moulds independently and locally right from product idea to G-code and machining. For micro components machining of the mould gets really tiny and the challenges like controlling part shrinkage and managing draft angles makes mould machining much more complex than usual.
However, the distinction line between micro moulding and the so called 'macro' sometimes seems to disappear as larger parts still can fit in micro mould but have high resolution features. At "Micromolds" we define 'micro' as when the part size is less than 1g or/and it has micro features (like microfluidic channels) or/and it has dimensional tolerances from 50µm to 5µm. Currently we are capable to machine with as little as 0.2mm milling cutters, thus achieving minimum inside corner radii of 0.1mm and to maintain +/- 0.05mm tolerance. We are also able to have 5:1 or 10:1 length-to-diammeter ratios. Moreover, for extremely small features we can push forward our machining limits with EDM machining.
