Engineered for precision-critical industries, our nickel alloy
electroplated mold cavities and cores combine the benefits of
electroforming (for complex geometry replication) with CNC
machining (for micron-level trimming)—delivering ±0.003mm accuracy
to meet the strictest molding demands. Ideal for producing parts
with intricate details, smooth surfaces, and multi-material
compatibility, these molds bridge high precision and versatility.
Core Advantages: Electroplating + CNC = Unmatched Precision
±0.003mm Precision: From Complex Shapes to Tight Tolerances
Our dual-process approach (electroplating + CNC) ensures precision
at every stage:
- Electroplating for Geometry: Electroformed nickel alloy replicates complex cavity/core details
(e.g., 0.05mm micro-ribs, 3D curved surfaces) with 99.9%
fidelity—critical for parts like medical microfluidic channels or
automotive sensor housings.
- CNC Trimming for Tolerance: Post-electroplating, CNC machining (5-axis) refines edges, mating
surfaces, and critical dimensions to ±0.003mm—eliminating
electroforming "overhangs" and ensuring perfect part fit.
- Surface Perfection: Electroplating delivers Ra ≤0.01μm mirror finishes (no
post-polishing needed), while CNC deburring removes micro-burrs,
ideal for optical lenses or sealing components where surface
smoothness impacts performance.
Nickel Alloy Durability: Corrosion-Resistant & Long-Lasting
Built with high-performance nickel alloys, these molds excel in
demanding production environments:
- Material Strength: Nickel-cobalt alloy (15-20% Co) offers 50-55 HRC hardness and
resistance to wear, supporting ≥200,000 production cycles—perfect
for high-volume automotive or electronics parts.
- Corrosion Resistance: Pure nickel (99.95%) resists chemicals, oils, and moisture,
making it ideal for medical molds (contact with bodily fluids) or
industrial molds (exposure to coolants).
- Thermal Stability: Withstands temperatures up to 300°C (nickel-chromium variants),
suitable for molding high-temperature plastics (PEEK, PPS) or metal
alloys.
Multi-Material Compatibility: Adapt to Your Production Needs
Designed to work with diverse molding materials, these molds reduce
the need for multiple tooling sets:
- Plastics: Optimized for engineering plastics (ABS, PC, nylon) and
high-performance resins (PEEK, LCP)—critical for electronics
housings and automotive components.
- Metals: Compatible with low-pressure metal injection molding (MIM) of
alloys like stainless steel or titanium—ideal for medical surgical
tools.
- Composites: Handles fiber-reinforced composites (carbon fiber, glass-filled
plastics) without surface damage, supporting lightweight aerospace
parts.
Application Scenarios: Where Precision Meets Versatility
Our nickel alloy electroplated mold cavities and cores serve
industries demanding both complexity and accuracy:
- Automotive: Producing LED reflector molds (mirror finish for light
uniformity) and turbocharger seal cavities (±0.003mm tolerance for
leak prevention).
- Medical Devices: Molding microfluidic chip cavities (0.1mm channels) and surgical
instrument handles (corrosion-resistant, biocompatible surfaces).
- Electronics: Manufacturing micro-connector cores (precise pin spacing) and
smartphone camera lens molds (Ra ≤0.01μm surface for optical
clarity).
- Optical Components: Creating lens molds and prism cavities where surface smoothness
directly impacts light transmission.
Tailored to Your Needs: Customization & Expertise
We adapt our molds to your unique part designs and production
goals:
- Geometry Customization: Support for complex features—from undercuts and thin walls
(0.08mm) to 3D asymmetrical shapes—with DFM (Design for
Manufacturability) input to optimize electroplating and CNC steps.
- Alloy Selection: Choose nickel alloy based on your needs: pure nickel for
biocompatibility, nickel-cobalt for wear resistance, or
nickel-copper for conductivity.
- Size Flexibility: Molds range from micro-components (φ3mm) to large panels
(600*400mm), with CNC machining ensuring consistency across all
sizes.
