1. Micro injection molding is a manufacturing technology for micron-level (1-1000μm) precision plastic parts. By 2025, through technological iteration, it has achieved:
Ultra-fine molding: the minimum part weight can reach 0.1mg (such as insulin pump gears), and the wall thickness is as low as 10μm;
Complex structure capabilities: integrated microchannels (width 50μm), multi-material embedding (metal-plastic composite);
Efficiency innovation: Cycle Time is shortened to 2-5 seconds (traditional processes require 15-30 seconds), suitable for million-level mass production.
2. Core technical points and breakthroughs
Micro mold design
Material selection: tungsten steel (hardness HRA 90) or nanocrystalline ceramics (wear resistance increased by 300%);
Processing technology: laser micro-engraving (precision ±0.5μm) + ion beam polishing (surface roughness Ra<0.01μm);
Temperature control system: integrated microchannel heating in the mold (temperature control accuracy ±0.1℃) to inhibit premature cooling of the melt.
Progress in materials science:
LCP (liquid crystal polymer): temperature resistance of 260℃, excellent fluidity (medical sterilized parts)
PEEK MT (micrometer level): creep resistance, biocompatible (implantable sensors)
Photosensitive resin composites: photocuring-assisted molding (optical microlens array)
Process parameter optimization
Injection stage: screw diameter ≤14mm, injection pressure increased to 300MPa (conventional molding 5-150MPa);
Pressure control: three-stage attenuation (200→100→50MPa), compensation for microscale shrinkage (0.5-1.2%);
Cooling strategy: liquid nitrogen instant cooling (-196℃) locks the microstructure and reduces internal stress.
3. Innovative application areas in 2025
Medical health
Intravascular stent delivery system (outer diameter 0.5mm, dual-material gradient structure);
Neural probe array (128 channels, electrode spacing 20μm).
Consumer electronics
TWS headset micro acoustic mesh cover (aperture 15μm, precise control of air permeability);
Folding screen mobile phone hinge damping module (wear-resistant life> 500,000 times).
Optics and communications
Fiber optic connector V-groove (angle accuracy ±0.01°, insertion loss <0.1dB);
AR glasses diffraction optical waveguide (nanoimprinting synchronous molding, 30% improvement in light efficiency).
IV. Technical challenges and solutions
Microfluidic balance problem
Simulation optimization: Moldflow 2025 version adds a "microscale flow module" to predict the weld line position error <5μm;
Vacuum assistance: vacuum degree in the mold cavity <1kPa, reducing bubble defects (yield increased to 99.8%).
High-precision requirements for demolding
Electrostatic adsorption demolding (voltage 5kV, gravity accurate to μN level);
Bionic gecko foot mold coating (controllable adhesion, protecting microstructure integrity).
Detection technology upgrade
Ultra-depth 3D microscope (Keyence VHX-7000) achieves 0.01μm-level dimension measurement;
AI visual sorting system (false detection rate <0.001%), with a flow rate of 3,000 pieces/minute.
5. Trends in the integration of cutting-edge technologies
Intelligent production
The digital twin system maps the molding process in real time (data sampling rate 1MHz) and dynamically corrects parameter deviations;
Self-learning injection molding machines (such as Engel viper 12) optimize the process through neural networks (reducing the number of mold trials by 80%).
Green manufacturing
Bio-based PLA microsphere granules (reducing carbon footprint by 60%), adapted to insulin pump housings;
Micro-particle recycling system (processing capacity 1kg/h), with a waste recycling rate of 95%.
Interdisciplinary integration
Micro-injection molding + 3D printing (Nanoe Zetamix equipment) to achieve metal-ceramic composite micro-gears;
Photocuring-assisted micro-molding (UV-LED array) to simultaneously complete structural and surface functionalization
