Pen model core: Analysis of key technologies for precision machining and mold design
1. Core functions and design principles of core
Functional positioning:
Complex inner surfaces such as ink pipe grooves, threaded structures, pen tip fixing holes, etc.
Match with the cavity to control the dimensional accuracy of the plastic parts (tolerance ≤±0.02mm).
Design points:
Material selection:
Pre-hardened steel (such as NAK80, HRC38-42, suitable for complex structures).
Mirror steel (S136H, HRC58-62, suitable for high-gloss needs).
Structural adaptation:
Demolding slope: 1°-3° (adjusted according to the shrinkage rate of the plastic part material).
Cooling waterway: 3D follow-up waterway (distance ≤20mm, improving cooling efficiency by 30%).
Insert design:
Pen tip metal insert (H7/h6 interference fit, anti-rotating).
Decorative ring inserts (laser welding positioning to avoid deformation of plastic parts).
2. The entire process of processing technology
01. Rough machining (5-axis CNC milling)
Target: Remove 80% of the margin and leave 0.5mm finishing margin.
Parameters: Feed speed: 0.3mm/rev (avoid vibration).
Tool: φ20mm integral cemented carbide milling cutter (4 edges, spiral angle 45°).
02. Heat treatment
Vacuum quenching:
Insulated at 1050℃ for 1.5 hours, cooled by nitrogen (deformation amount<0.03mm).>
Deep cold treatment: Soak in liquid nitrogen (-196℃×2 hours) to improve material stability.
03. Finishing (slow-wire-moving + EDM)
Slow-moving wire cutting:
0.2mm brass wire, surface roughness Ra≤0.8μm.
Electric spark processing:
micro-pore processing (φ0.3mm nozzle hole, depth diameter ratio 10:1).
04. Mirror polishing
Process route:
Diamond cast polishing (particle size 0.5μm) → Ultrasonic grinding (Ra≤0.02μm).
Detection:
A white light interferometer (ZYGO NewView 9000) detects surface quality.
05. Coating treatment
PVD coating:
CrN+DLC composite coating (thickness 3μm, friction coefficient<0.08).>
Laser cladding:
local reinforcement (such as thread area, hardness HV1200).
3. Key technological innovation points
Microstructure processing:
Leather etching (depth 0.05mm, anti-slip).
Microlens array (for stylus, diameter φ0.5mm).
Intelligent cooling system:
Embedded temperature sensor (real-time monitoring of mold temperature).
Pulse cooling technology (40% water saving, shortening molding cycle).
Modular design:
Quickly change the core (magnetic positioning, replacement is completed in 30 seconds).
4. Failure mode and solution
Question Type Phenomenon Causes Solution
Wear Surface scratches (>Ra0.4μm) Coating falls off Using DLC+TiAlN multi-layer coating
Deformation Core bending (>0.05mm) Improper heat treatment Increased aging treatment (200℃×12h)
Sticky mold Remaining plastic parts Inadequate polishing Nano-scale polishing (Ra≤0.01μm)
fracture Insert fall off Insufficient interference Use the thermal sleeve process instead (temperature difference of 50℃ assembly)
5. Quality inspection and lifespan management
Precision detection: Industrial CT scan (detect internal defects, resolution 5μm).
Blu-ray 3D scanner (compared with CAD model, deviation<0.01mm).<>
Life expectation:
Based on the number of injection moldings (usually >500,000 times) and surface roughness attenuation model.
Maintenance strategy:
Regular nitriding treatment (restores surface hardness).
Laser cladding repair (local damage area).
6. Typical application scenarios
High-end stylus:
Integrated silicone conductive contacts (core EDM processing 0.1mm gap).
Environmentally friendly and biodegradable pen:
Special high-gloss core for PLA materials (polished to Ra0.02μm).
Medical pen:
Titanium alloy insert (biocompatibility, electrolytic polished after CNC processing).
Through the integration of materials, processes and intelligent technology, the pen model core can achieve a leap from μ-level accuracy to millions of life, meeting the extreme needs of consumer electronics, medical care and other fields.
