MTD is one of only two vertically integrated micro molding companies in the U.S. and manufactures some of the tiniest medical devices in the world. The smallest micromolded component in the world is manufactured at MTD and is 520 parts per single plastic pellet (a plastic pellet is about the size of a sesame seed). Our skilled staff and high precision equipment are capable of micromolding to sub-micron level feature sizes.
