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
**Industry Applications**
|**Medical Devices**| Endoscope components, insulin pump gears, surgical robot parts | Biocompatibility, sterile molding, miniaturization |
|**Electronics** | 5G fiber connectors, MEMS sensor housings, VR optical lenses | EMI shielding, ultra-fine structures, heat resistance |
|**Automotive**| Camera mounts, EV battery insulation parts | Vibration resistance, chemical durability, long lifespan |
|**Consumer Tech**| TWS earphone components, smartwatch buttons, foldable screen hinges | Lightweighting, wear resistance, high-volume cost efficiency |
Why Choose Our Micro Molding Services?
- **Micro Molding Machines**: German/Japan micro injection machines+ high grade precision molds but more cost-effective than traditional injection molds and molding.
- **End-to-End Support**: Material selection, Moldflow simulation, post-processing (plasma cleaning, laser trimming)
- **Lead Time**: Small Molds, short lead time.
Say goodbye to the challenges of micro component processing - the preferred integrated solution for micro injection molding in the medical/electronic industry!
