Customized Metal Parts 5-Axis CNC Machining: Precision for Metal-Specific Needs

Core Service Parameters Comparison (Metal-Specific & Customizable)

Key Advantages: Customized Solutions for Metal Parts

1. Metal-Specific 5-Axis Machining Expertise

• High-Hardness Metals: For 4140 alloy steel (50–55 HRC) or titanium Grade 5, we use ultra-hard carbide tools (WC-Co with 10% Co content) and high-torque spindles (40 N·m) to avoid tool wear, ensuring consistent tolerance (±0.002mm) across batches.
• Thermal Deformation Control: For aluminum (prone to heat warping), we use high-pressure cooling (70 bar) and variable cutting speeds (1,500–3,000 RPM) to keep metal temperature ≤50℃—critical for thin-walled aluminum parts (0.5mm wall thickness) like electronic enclosures.
• Corrosion-Resistant Finishes: For 316L stainless steel medical parts, we add passivation (ASTM A967) or electropolishing to eliminate micro-pores, ensuring compliance with ISO 13485 and reducing bacterial adhesion.

2. Fully Customized Geometries for Metal Parts

• Multi-Sided Complexity: Machines 0–360° angled holes, spherical surfaces, and asymmetric features in one setup. For example, a customer’s aerospace aluminum bracket (6061) with 45° mounting holes and a curved stress-relief groove is produced with ±0.003mm alignment, avoiding repositioning errors.
• Thin-Walled & Micro-Features: Creates thin-walled metal parts (minimum 0.3mm wall thickness) and micro-features (0.1mm-diameter holes in brass) for electronics—using adaptive cutting technology to prevent metal deformation.

3. Tailored Solutions for Industry-Specific Metal Needs

• Aerospace: Titanium Grade 5 parts with AS9100 compliance—machined to ±0.001mm tolerance, with ultrasonic testing (UT) to detect internal defects, ensuring durability under high pressure.
• Medical: 316L stainless steel surgical instruments—polished to Ra ≤0.02μm, with no sharp edges (≤0.01mm radius) to reduce tissue damage, complying with ISO 13485.
• Automotive: 4140 alloy steel transmission shafts—heat-treated to 50 HRC, with concentricity ≤0.001mm to avoid vibration, meeting IATF 16949 standards.

Our Customization Process for Metal Parts

1. Requirement Alignment: Collaborate with customers to define metal material (e.g., "316L for corrosion resistance"), part geometry (CAD/STEP files), tolerance, and industry standards (e.g., AS9100).
2. Metal-Specific DFM: Provide 24-hour Design for Manufacturability analysis—e.g., adjusting a customer’s titanium part’s fillet from 0.1mm to 0.2mm to avoid tool breakage, or recommending 6061 over 7075 for cost savings if strength requirements allow.
3. Prototype Production: Manufacture custom metal samples in 4–6 days, using the same material and process as bulk production. Provide CMM inspection reports to validate precision.
4. Feedback Iteration: Refine the prototype based on customer feedback—e.g., tightening tolerance from ±0.005mm to ±0.003mm, or changing surface treatment from anodization to PVD.
5. Bulk Production: Launch mass production with automated 5-axis cells, conducting 100% visual inspection and 20% dimensional sampling to ensure consistency.

Quality Assurance for Custom Metal Parts

• Precision Testing: Use Zeiss CMM (±0.0005mm accuracy) for dimensional checks, Rockwell hardness testers for metal hardness verification, and salt spray chambers for corrosion resistance testing.
• Material Traceability: Provide mill certificates for all metals (e.g., ASTM B265 for titanium, ASTM A240 for stainless steel) to ensure compliance with industry standards.
• Certifications: Complies with ISO 9001—ensuring customized metal parts meet global quality requirements.

Heya Precision: Factory Overview & Production Excellence

Factory Basics: Location & Scale

• Strategic Location: Based in Dongguan, China’s core precision manufacturing hub—enabling efficient access to raw material suppliers, logistics networks, and global shipping ports (Shenzhen/Hong Kong), ensuring timely delivery for international clients.
• Optimized Space: Over 1000㎡ of dedicated production area, divided into functional zones (precision machining, electroforming, plastic molding, surface treatment, and quality inspection) to streamline workflows and minimize cross-contamination risks.
• Compliant Environment: Adheres to industrial safety and environmental standards, with well-ventilated workspaces, anti-static flooring in precision zones, and organized storage for mold components—reflecting our commitment to orderly, professional production.

Production Capabilities: Equipment & Processes

• Precision Machining Zone: Hosts high-speed CNC engraving machines (for intricate mold details) and multi-axis CNC machining centers—capable of handling complex mold geometries with dimensional tolerance as tight as ±0.005mm, critical for electroformed mold cores.
• Surface Treatment Zone: Features in-house mold texturing (pattern etching) and brushing finish equipment—eliminating reliance on third-party vendors to reduce lead times. We also offer outsourced texturing/brushing services for external mold manufacturers, showcasing our flexible capabilities.
• Plastic Molding Zone: Includes injection molding machines tailored for small-to-medium volume plastic parts, compatible with diverse resins (PC, PMMA, ABS) commonly used in automotive, electronics, and consumer goods industries.

Team & Quality Control

• Skilled Workforce: A 30+ team of experienced professionals, including 5+ senior mold engineers (with 10+ years in precision machining), 12+ certified technicians, and dedicated quality inspectors—ensuring every stage (from raw material intake to final mold testing) meets Heya Precision’s standards.
• End-to-End Quality Checks: Embeds strict inspection checkpoints:
  • Raw material verification (mold steel, resins) with supplier certificates;
  • In-process testing (CMM measurements for machining accuracy, surface roughness tests for texturing);
  • Final validation (mold trial runs, dimensional sampling) before shipment.

Support for OEM/ODM

• Flexible Production Lines: Accommodate small-batch prototype orders (e.g., 1–10 mold cores) and medium-volume production (100–5,000 plastic parts) without compromising precision.
• Collaborative Workflow: Dedicates project managers to OEM/ODM clients, ensuring clear communication between your team and our factory—from design confirmation (DFM analysis) to production scheduling and post-delivery support.
