• What Defines a “Micro” Part?

True micro parts are fractions of a pellet, weigh fractions of a gram, have tolerances of 0.0001–0.0002" (0.002–0.005mm), and have geometry seen only by the use of a microscope. In fact, the smallest molded component in the world is manufactured by MTD and is 520 parts per single plastic pellet in size! The component solutions MTD makes possible are beyond micro-approaching the "nano" level, for example, here are just some dimensions of our micromolded components:

• Microfluidic slots to 0.5 micron (0.000019")

• Total part length of 0.060" (1.5mm)

• Gate diameters as low as 0.002" (0.05mm)

• Core pins of 0.0027" (0.068mm) diameter

• Wall thickness as low as 0.0015" (0.04mm)

• Cavity and Core TIR less than 0.0001" (0.003mm)

• Overall part weight of 0.00012 grams

Micromolded parts can be micro in size but also be micro features in larger parts that require the same level of tooling tolerances for correspondingly tolerances held in plastic. These microscopic parts are used in medical devices such as catheter components, micro sensors, and resorbable implants. Newly emerging markets such as biomedical, MEMS, electronics, microfluidics, and nanotechnology are growth industries for micromolding.

We pride ourselves in helping you design the best possible micromolding solution for your particular application.
