Suitable For Multi-Material Molding (Plastics, Metals, Composites) | ±0.003mm High Precision

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.

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.

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.

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.

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.

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.

• Quality Assured: 100% inspection via CMM (Coordinate Measuring Machine) with ±0.001mm accuracy, verifying tolerance compliance and surface finish.
• Traceability: Full documentation (material certificates, electroplating process logs, CNC machining reports) to meet ISO 9001, IATF 16949 (automotive), and ISO 13485 (medical) standards.
• Technical Support: Dedicated engineers collaborate on part design, recommending alloy types and process tweaks to maximize mold performance and part quality.

Whether you need molds for intricate medical parts, high-volume automotive components, or precision optical tools, our nickel alloy electroplated cavities and cores—enhanced by CNC machining—deliver the accuracy, durability, and versatility your production demands. Backed by ±0.003mm precision, they ensure every part meets your strictest standards, from prototype to mass production.
