Micromolding—also known as micro injection molding—is a highly specialized manufacturing process used to create extremely small, three-dimensional plastic components with microscopic features and ultra-tight tolerances. This thermal form-change process transforms medical-grade polymers into precise, functional parts measured in millimeters—or even microns.

At MTD Micro Molding, micromolding is far more than a scaled-down version of traditional injection molding. It’s a distinct discipline that requires deep understanding of polymer science, micro manufacturing, and precision tooling. When plastics are molded at the micro scale, they behave very differently than in macro applications—demanding proprietary technology, purpose-built equipment, and decades of specialized expertise to achieve consistent results.

The Science Behind Micromolding

In the micro world, size reduction doesn’t happen linearly. As a component becomes smaller, its volume and surface area decrease at different rates, meaning materials flow, cool, and perform in entirely new ways. The same polymer used in a macro-sized part may yield dramatically different results when micromolded. That’s why MTD approaches every project with data-driven analysis, custom tool design, and precision metrology to ensure success at the smallest scales.

Why Micromolding Matters in Medical Device Manufacturing

Micromolding enables innovations in minimally invasive medical devices, drug delivery systems, and microfluidic components—applications where part size, reliability, and biocompatibility are critical. With decades of experience dedicated exclusively to medical micromolding, MTD has mastered the art of pushing the limits of what’s possible, producing parts others consider “unmoldable.”

Micromolding is where material science, engineering innovation, and precision manufacturing converge—down to the micron.
