Engineered to solve the "complex 3D geometry + high precision"
dilemma in mold-making, this customizable nickel alloy
electroplated mold combines two game-changing processes:
electroforming (for stress-free, uniform nickel alloy bases) and
multi-axis machining (for micron-level trimming of 3D curves, deep
cavities, and asymmetrical features). 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.
Core Advantages: Multi-Axis Machining + Electroplating = Complexity
Without Compromise
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 联动 (5-axis 联动) 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℃).
Application Scenarios: Where 3D Complexity Meets Precision
Our molds excel in industries demanding "intricate 3D shapes +
micron-level accuracy":

grooves, 0.15mm depth) and endoscope component cavities (3D curved
lumens for fluid flow) — complies with ISO 13485.
- Automotive High-Performance Parts: Molds for transmission gear cavities (internal 3D ribs for
strength) and EV battery connector housings (asymmetrical 3D slots
for wire routing) — aligns with IATF 16949.
- Optical Engineering: Cavities for lens mounts (3D curved seats, Ra ≤0.008μm) and laser
module housings (3D alignment features, ±0.001mm tolerance) — meets
ISO 10110 optical standards.

parts, pure nickel for optical-grade surface finish.
- Prototype & Validation: Produce 1-2 prototype molds (14-18 days) to test 3D feature
functionality—using 3D scanning (±0.0005mm accuracy) to verify
curve/undercut compliance before full production.
