What is Micro Molding?
Micro injection molding is a specialized form of plastic injection molding, focused on next-generation parts that need to be small but still retain tight tolerances and complex features. Many product developers don’t know that smaller parts can be made faster and cheaper on small machines.
The Micro Molding Process
Micro molding involves more than just using a small machine. The secret to making many tiny parts that are very close together is to control heat in the micro mold. To do this, micro injection molding machines have sophisticated temperature sensors and digital microcontrollers that are more precise than their larger cousins.
The barrel of the micro injection molding machine is much shorter than its full-sized counterpart. This makes it fast and easy to clean when changing over to new material. The greatest advantage of micro injection is that the micro molding machine can be cycled much more quickly while at the same time consuming far less resin. This results in great cost savings and reduced production time.

Micro Molding Applications
There are many cutting-edge technologies that need small, lightweight, and strong parts. For all of these and more, micro injection is an ideal solution. Our services can also scale up from a few grams to shot weights of 300 grams or more.
Common Questions
Micro Molding FAQs
There are three common rapid prototyping services Star Rapid provides.
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 micro molded part sizes smaller than this.
Most conventional plastic resins are supported for micro molding, but it may not be possible to use additives (glass fiber reinforced) because this will impede the flow through a small gate.
Mold tools for micro molding are the equal of their full-sized counterparts and can last for 100K cycles or more, depending on resin.
