High Precision Electroformed Mold Core Factory – Direct Supply of High Accuracy Components for Molds
As a specialized factory focusing on high precision electroformed mold cores, we directly supply critical components for mold manufacturers, precision injection molders, and micro-structural part producers. Electroformed mold cores—crafted via advanced metal deposition technology—are the "heart" of high-precision molds, enabling the replication of tiny, complex features in plastic, rubber, or metal parts. Our factory combines in-house electroforming expertise with direct supply capabilities, delivering mold cores with micron-level accuracy, flawless surface finishes, and tailored designs—eliminating middlemen to ensure quality consistency and cost efficiency.
Why Choose Our Electroformed Mold Cores?
Traditional mold cores (machined or cast) struggle with the micro-details and tight tolerances required for modern precision molds—our electroformed solutions solve these challenges:
- Unmatched Micro-Precision: Machining hits limits at 0.01mm features, but electroforming replicates details as small as 0.001mm (e.g., 0.05mm ribs, 0.1mm holes, or intricate textures). This is critical for molds producing microelectronics, medical devices, or miniaturized components;
- Surface Perfection: Electroformed cores achieve Ra ≤0.01μm mirror finishes or controlled textures without post-processing, ensuring molded parts have smooth surfaces (no "tool marks") or consistent textures (e.g., for grip or branding);
- Direct Supply Advantage: As a factory, we control every step from design analysis to electroforming—no middlemen mean faster lead times (7–10 days for prototypes), better cost control, and direct technical support for your mold needs.
Core Advantages of Our Electroformed Mold Cores
1. High Accuracy for Critical Mold Performance
Our electroformed mold cores maintain:
- Dimensional Tolerance: ±0.003mm for critical features (e.g., cavity edges, micro-protrusions); ±0.005mm for general areas—ensuring molded parts match design specs exactly;
- Shape Consistency: Perfectly replicates 3D CAD designs, even for complex geometries (e.g., curved cavities, undercuts, or asymmetrical structures) that CNC machining can’t achieve without distortion;
- Interchangeability: Every core in a batch matches the master design, critical for multi-cavity molds where part uniformity is key.
2. Material & Durability Tailored for Molds
We use high-performance materials optimized for mold core longevity:
- Electroformed Nickel Alloys: Offer 50–55 HRC hardness, resisting wear from repeated injection cycles (withstands 150k+ cycles for plastic molds);
- Corrosion Resistance: Treated surfaces resist resin chemicals, cleaning agents, and humidity—extending core lifespan by 30% vs. standard steel cores;
- Custom Alloys: Copper-nickel or nickel-cobalt blends for enhanced conductivity (for hot-runner molds) or heat resistance (for high-temperature resins like PEEK).
3. Direct Supply: From Factory to Your Production Line
As a direct supplier, we streamline the process:
- Design Collaboration: Our engineers review your 3D mold designs (CAD, STEP) for electroforming feasibility, suggesting optimizations (e.g., draft angles for micro-features) to reduce costs;
- Fast Turnaround: 7–10 days for prototypes, 15–20 days for mass production (500+ cores)—faster than traditional supply chains with distributors;
- Full Traceability: Each core comes with inspection reports (CMM measurements, surface finish data) and material certificates, supporting your quality audits.
Applications: Where Precision Matters Most
Our electroformed mold cores excel in molds producing:
- Microelectronics Parts: Connector housings, sensor casings, or circuit board components (with 0.1–0.5mm features);
- Medical Devices: Syringe barrels, catheter components, or diagnostic tool parts (where surface smoothness and dimensional accuracy impact safety);
- Consumer Electronics: Miniature gears, watch components, or smartphone button molds (where aesthetics and fit drive user experience);
- Precision Plastics: Optical lenses, microfluidic chips, or cosmetic packaging (with tight tolerance requirements).
