Core Advantages: Multi-Axis Machining + Electroplating = Complexity Without Compromise
Unlike traditional 3-axis machining (limited by flat/linear cuts) or standalone electroforming (struggling with sharp 3D edges), this hybrid approach delivers ±0.001mm tolerance for parts like aerospace turbine blade cavities (with 3D curved cooling slots) or medical instrument housings (with asymmetrical grip contours). Built with high-performance nickel alloys, it balances durability and precision—critical for high-cycle production of complex components.
Multi-Axis Machining: Master of 3D Complexity
Multi-axis (5-axis/6-axis) machining eliminates the "flaws of flat machining," enabling molds with intricate 3D features that traditional methods can't replicate:
- 3D Curve Accuracy: Cuts 3D curved surfaces (e.g., optical lens mount cavities) with ±0.001mm deviation from CAD designs—critical for parts where "0.002mm curve error ruins assembly" (e.g., aerospace sensor housings).
- Deep Cavity & Undercut Handling: Machines deep cavities (depth-to-width ratio 5:1) and undercuts (0.1mm clearance) without tool collision—ideal for medical instrument molds (with hidden grip grooves) or automotive transmission part cavities (with internal ribs).
- Reduced Setup Errors: 5-axis machining consolidates 3+ traditional setups into 1, cutting "repositioning errors" by 90%—ensuring 3D features (e.g., a cavity's curved wall + adjacent hole) align to ±0.0008mm.
Electroplating: The Foundation of Uniformity & Stability
Electroforming lays a stress-free, uniform nickel alloy base—critical for maintaining multi-axis machined precision over time:
- Stress-Free Structure: Nickel ions deposit layer-by-layer (0.001mm per hour), creating a mold base with no internal stress (unlike machined steel, which warps under heat). This ensures 3D features stay within ±0.001mm tolerance across 150,000+ production cycles.
- Uniform Material Density: Electroplated nickel alloy has 99.9% density (no porosity), avoiding "weak spots" that cause wear in high-stress areas (e.g., deep cavity corners).
- Surface Perfection: Electroforming delivers Ra ≤0.01μm as a base, which multi-axis machining refines to Ra ≤0.008μm—ideal for parts where surface smoothness impacts function (e.g., fluid flow in medical device cavities).
Nickel Alloy Durability: Built for High-Stress Production
The right nickel alloy ensures the mold withstands the demands of complex part production:
- Wear Resistance: Nickel-cobalt alloy (50-55 HRC) resists abrasion from high-pressure molding of glass-filled plastics (e.g., 30% glass-filled PA) or metal powders—extending mold life to 200,000+ cycles.
- Corrosion Resistance: Nickel-chromium alloy stands up to coolants, disinfectants, and industrial fluids—critical for medical molds (contact with bodily fluids) or aerospace molds (exposed to hydraulic fluids).
- Thermal Stability: Withstands 280℃+ (nickel-chromium variants), supporting high-temperature molding of PEEK (250℃) or titanium alloy MIM (200℃).
