• 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 through a microscope. The component design solutions enabled by MTD are truly micro with features that approach "nano" level.

For example, here are just some dimensions of our micro-molded parts :

• 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

In fact, the smallest molded component in the world is manufactured by MTD.
520 of these tiny parts are produced by a single plastic pellet the size of a sesame seed!

Micro-molded parts can be micro in size; but MTD can produce micro features on larger parts that require the same level of tooling. These micro-featured parts are used in medical devices such as catheter components, micro sensors, and bio-absorbable implants. New markets for these micro-molded features include the biomedical, MEMS, electronics and micro-fluidic fields, as well as nanotechnology.

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