In-depth analysis of pen model core technology: the complete chain from design to application
1. Core technical parameters and material selection logic
Material Matching Matrix
Application scenarios Recommended materials Key Performance Cost Level
High-gloss pen rod S136H (mirror steel) Ra≤0.02μm, strong corrosion resistance High
Complex structural parts NAK80 (pre-hard steel) Good processability, deformation capacity<0.03mm middle="">
Wear-resistant screw area ASP60 (powder high-speed steel) HRC68-70, wear resistance increased by 300% Extremely high
2. Innovative solution for intelligent cooling system
Topological optimization waterway design
simulation tool: Use Moldex3D to simulate heat flow to generate a follow-up waterway (cooling efficiency is improved by 40%).
Structural innovation:
Spiral waterway (8mm spacing, reducing temperature difference gradient). Fountain-type water outlet (avoid blind spots, mold temperature uniformity ±1℃).
Dynamic temperature control strategy
Sensor deployment: Embed K-type thermocouple (accuracy ±0.5℃) in the core head.
Control algorithm: PID+fuzzy logic, automatically adjust the water flow rate according to the thickness of the plastic part (energy saving 25%).
3. Database of failure mode and prevention plan
Failure mode Preventive measures 3D optical profiler (roughness detection)
Screw tooth strain Insert pre-plated CrN (thickness 2μm) Friction and wear tester (5000 cycles)
Plastic parts sticking mold Surface DLC coating (coefficiency of friction<0.05)<>
Uneven cooling leads to deformation Zoned temperature control system (temperature difference<3℃) infrared="" thermal="" imager="">
4. Industry application benchmark cases
Luxury pen
Technical challenge: 0.3mm decorative ring insert (laser welding positioning to avoid deformation of plastic parts).
Solution: Use thermal expansion coefficient matching technology (copper insert + PC plastic parts, ΔT<5ppm>
Ultrasonic assisted injection molding (wire strength >25MPa).
Medical pen
Special requirements: Biocompatible, no blind spot cleaning.
Innovative design: titanium alloy core (TC4, anodized treatment).
Integrated flow channel (avoiding residues of medicine and comply with ISO10993 standard).
Environmentally friendly biodegradable pen
Material breakthrough: PLA+ bamboo fiber composite material.
Process adaptation:
Mirror polishing (Ra≤0.03μm, reducing mold release resistance).
Micro-pore exhaust design (diameter φ0.05mm, preventing burning of gas).
5. Future technology trends
Additive Manufacturing (3D Printing)
Advantages: Complex runners are integrated to reduce assembly errors.
Case: SLM printing Inconel718 core (temperature resistant to 1200℃, used for metal injection molding).
Digital Twin Technology
Application: Optimize injection molding parameters through real-time feedback of IoT sensors (shortening debugging cycle by 50%)
Sustainable design
Direction: Removable and replaceable core (extend mold life by 3-5 times), and use recycled steel (reduce carbon emissions by 40%).
6. Economical core design guide
Cost control strategy:
Standardized inserts (reduce customization costs).
Segmented cooling (reduces processing difficulty).
Quick change plan:
Magnetic positioning + pneumatic locking (model replacement time < 5 minutes).
Through deeply integrating materials science, precision machining and intelligent technology, the pen model core is evolving from a single functional component to a high performance, long life and intelligence, providing core support for the high-end manufacturing field.
