Micro Injection Molding: Precision Plastic Parts for High-Tech Industries

Micron-Level Accuracy for Miniature & Complex Components

What is Micro Injection Molding?

Micro injection molding is an advanced manufacturing process designed to produce milligram-weight, micron-tolerance plastic parts. Utilizing high-precision molds, micro-dosing injection systems, and specialty engineering materials, it enables the production of ultra-small, intricate components that conventional injection molding cannot achieve.

Key Advantages

✅ Ultra-High Precision

Part weights as low as 0.001g with tolerances down to ±5μm (1/20th of a human hair)

Capable of 0.05mm ultra-thin walls (e.g., microfluidic channels)

✅ Wide Material Compatibility

Supports medical-grade PEEK, LCP (autoclavable), biodegradable PLA, liquid silicone rubber (LSR), and more

Reduces material waste by 50%+ (micro-dosing minimizes scrap)

✅ High Efficiency & Consistency

Fully automated production with cycle times as fast as 5-10 seconds per shot

Maintains 99.9% dimensional stability (CPK≥1.67) even in million-unit production runs

✅ Complex Geometry Capability

Single-step molding of micro gears, lens arrays, snap-fit features, eliminating secondary assembly
