Why Choose Star Rapid for Micromolding?

If you need to manufacture small plastic parts and components with micron tolerances, micromolding is your solution. This specialized  process uses tiny molds and dedicated machinery to create high-precision small parts with a minimal investment. To get your micromolding project done right, you need a team with experience working successfully at this small scale. Here’s why Star Rapid is the smart choice.

An International Team with Industry-Leading Expertise

Our engineering and project management specialists have centuries of combined experience in micromolding, rapid prototyping and low-volume manufacturing of small-scale parts. Our state-of-the-art facilities in Asia allow us to handle micromolding for organizations worldwide.


Babyplast Micromolding

Our high-quality, Italian-made Babyplast machines are specifically designed to offer the precision that’s necessary to have when working on small-scale parts. They have precise temperature and pressure controls for maximum efficiency, while using steel tools that on average are 40% less expensive than full-sized tools. This is just one of the many reasons why our micromolding services are a cut above.

Quality Injection Molding and an Efficient Process You Can Count On

We prioritize both quality and efficiency to give our clients superior results on a schedule that works for them. We have 2- to 48-hour response times on RFQ’s 95% of the time, as well as a 90%+ OTD (on-time delivery) against our commitments.

Micromolding Quick Facts

What are the smallest parts you can produce?

Part size is mostly limited by gate size. Shot weight is limited to a few grams, and part size is normally 3mm2. Consult our engineers to discuss micromolded part sizes smaller than this.

Can I use any type of plastic resin?

Most conventional plastic resins are supported for micromolding, but it may not be possible to use additives (glass fiber reinforced) because this will impede the flow through a small gate.

How durable are micromolding tools?

Mold tools for micromolding are the equal of their full-sized counterparts and can last for 50K cycles or more, depending on resin.
