Micro molding is a specialized form of plastic injection molding for making parts on a very small scale. Finished components can easily weigh less than 1 g and measure smaller than 1 mm in cross-section. We can understand how micro molding differs from conventional plastic injection molding from several aspects.
First of all, small parts use smaller molds, and these have equally small cavities, gates and runners. Such tools, and the resulting parts that they make, are highly sensitive to fine adjustments in pressure or temperature. But larger machines are more difficult to control precisely. Secondly, Micro molding consumes much less raw material. This includes not only material used to make the part but also leftover resin in the gate and runner system as well as the barrel. And the third advantage of micro molding is faster cycle times. Micro molding machines have short, compact barrels and the gates and runners are also of short length. Therefore even multi-cavity molds can be cycled much more quickly then their larger counterparts.
Micro molding can be widely used for medical, optical, electronic, automotive, and anything that needs plastic components. The range of potential applications is constantly expanding and is only made possible with advanced manufacturing solutions that support the latest product designs.
