Micro Molding
Description
Micro-molding is a highly specialized manufacturing process that produces extremely small, high-precision thermoplastic parts and components with micron tolerances. The micro molding process starts in a tooling department where a mold is created that has a cavity in the shape of the part desired. Thermoplastic or resin is rapidly injected into the cavity, creating the component or part at high speed.
For clarity, we will spell it “micro molding” but elsewhere you may see it spelled micromolding or even micro moulding for our European friends. Spelling aside, interest in this art has dramatically increased in engineering circles, especially in the last decade.
The rise of micro molding is due to increased interest from designers and manufacturers producing smaller, lighter, and more precise devices and specialized equipments. In order to miniaturize technology, OEMs must first procure high precision, micro-featured plastic parts.
So, what is micro molding and how is it different from molding small parts? Part size is an obvious factor, but not the only factor that matters. True micro molding produces a component or part that is:
micro in size
micro in features
micro in tolerances.
Accumold believes micro molding involves much more than overall part size, extending into geometry, complexity and tolerances.

Frequently Asked Questions
Micro molding is a specialized manufacturing process that produces extremely small, high-precision thermoplastic parts and components with micron tolerances.
The micro molding process starts with creating a mold with a cavity in the desired shape of the part. Thermoplastic or resin is then injected into the cavity at high speed to create the component or part.
Micro molding goes beyond just the size of the part. It also focuses on producing components that are micro in features and tolerances, extending into geometry and complexity.
Micro molding has gained interest from designers and manufacturers due to the need for smaller, lighter, and more precise devices and specialized equipment. It allows for the production of high precision, micro-featured plastic parts.
While the term "micro" suggests size, micro molding is not directly related to 3D printing or nano-printing. It primarily focuses on the manufacturing process of thermoplastic parts with micron tolerances.
