Micro Injection Molding Services: Precision Parts You Can Rely On

Micro injection molding is the most advanced way to produce ultra-small plastic parts with tight tolerances. The secret is controlling heat inside many small cavities packed closely together. This is only possible using precise digital microcontrollers.

Benefits of Micro Injection Molding

Here’s how micro-injection molding addresses your most pressing challenges:

Exceptional precision for tiny features:

Micro injection molding is the most advanced way to produce ultra-small plastic parts with tight tolerances. The secret is controlling heat inside many small cavities packed closely together. This is only possible using precise digital microcontrollers.

Lower material use, less waste:

Small shot sizes using the micro injection molding process reduce scrap and help control material cost.

Scalability for diverse production needs:

Micro injection molding is suitable for both small production runs and large-scale manufacturing, providing flexibility for various project demands.

Compatibility with advanced materials:

The process supports hundreds of plastic resins and a wide range of innovative materials. They include high-performance polymers and biocompatible resins, expanding its application across industries such as medical, electronics, aerospace and automotive.

Faster changeovers and throughput:

Compact barrel systems can reduce purge/cleaning time during material changes and support quicker turnaround.

Potentially lower tooling cost and lead time:

The smaller scale of micro molds reduces the tooling investment by about 40%. It may also reduce machining time compared with conventional tooling.

Common Questions

Procision Micro Injection Molding Service FAQ

Find answers to common questions about micro plastic injection molding services, mold design, and how these services help industries like medical, electronic, agriculture, and consumer products achieve their goals.

What is micro injection molding?

Like its conventional counterpart, micro injection molding works by injecting liquid plastic resin into a mold cavity under pressure, where the material is cooled to form a solid plastic part. The difference lies in the small size of the gates, runners and cooling channels, which demands much finer temperature and pressure control to maintain accuracy and consistency for miniature parts. 

The benefits of micro injection molding include reduced tooling costs, shorter production lead times, faster cycle times, reduced material consumption and waste, and tight tolerances on a micro scale.

Micro injection molding costs are calculated as the sum of four primary components:

  1. Material cost – Plastic resin, mold release agent and tooling raw material, all of which are much lower than with conventional injection molding.
  2. Direct labor: Toolmaking, testing, production – any task that adds value to the product.
  3. Indirect labor: Engineering design, packing and shipping, administration.
  4. Overhead: Insurance, utilities, plant maintenance, tax, etc.

The tools used in micro injection molding are made from the same durable steels as those of conventional molding. However, they are likely to last much longer because of the reduce injection pressures and lower heat build-up.
