Custom High-Precision Brushed Texture Cavity Molds for Automotive Parts

Core Product Parameters Table

Key Advantages: Engineered for Automotive Excellence

• Ultra-Precise Brushed Texture Replication
  Our proprietary CNC brushing and EDM processes create brushed textures with line width as fine as 0.02mm, maintaining angle consistency within ±1° across the entire mold surface. This ensures every automotive part (e.g., dashboard trim, door handle inserts) has uniform grain direction and depth—eliminating "patchy" textures that harm brand perception in premium vehicle lines.
• Customization for Automotive Aesthetics
  We tailor textures and mold designs to match your brand’s visual language:
  • Brushed Patterns: Straight (0°), diagonal (45°), or swirling "random" brushed textures, with adjustable line density (10-50 lines/mm) for matte to semi-gloss effects.
  • Complex Geometries: Cavity molds for 3D curved parts (e.g., curved dashboard panels) or parts with undercuts (e.g., gear shift surrounds), ensuring texture continuity even on contoured surfaces.
  • Branding Integration: Embed logos or micro-text (0.5mm font) within brushed textures for subtle brand differentiation (e.g., luxury car interior trim).
• Durability for Automotive Production Environments
  Our cavity molds use automotive-grade steel (H13, S136) with heat treatment (HRC 50-55) and TiAlN coating, resisting wear from high-temperature plastics (PP, ABS, PC/ABS) and repetitive injection cycles. They withstand:
  • Temperatures up to 220°C (for PC-based automotive parts).
  • Corrosion from mold release agents (passes 3,000h salt spray test per ISO 9227).
  • 1,000,000+ cycles without texture degradation—critical for mass-produced parts (e.g., 500,000+ units/year vehicle models).
• Automotive-Specific Optimization
  We design molds to address automotive manufacturing challenges:
  • Reduced Cycle Time: Integrate conformal cooling channels to cut cooling time by 20%, matching automotive production line speeds (30-60 parts/hour).
  • Scratch Resistance: Post-texture hardening (400HV surface hardness) ensures molded parts resist scratches from daily use (passes Ford BN 108-13 scratch test).
  • Color Compatibility: Brushed textures are optimized for automotive paints/coatings, ensuring consistent color absorption (ΔE ≤1.0) across parts.

Application Scenarios

• Interior Parts: Molds for dashboard trim, door handle inserts, center console panels, and steering wheel accents.
• Exterior Parts: Molds for side mirror housings, grille trim, and window surround trims.
• Functional Components: Molds for gear shift knobs, seat adjustment levers, and HVAC control panels.

Our Service Commitment

• Rapid Prototyping: 5-7 day turnaround for CNC-machined prototypes with brushed texture samples, validated via 3D scanning (accuracy ±0.002mm).
• Automotive Compliance: Molds meet IATF 16949 standards, with full traceability (material certificates, CMM reports) for automotive supply chains.
• DFM Support: Our engineers optimize mold design for texture replication and production efficiency—e.g., adjusting draft angles to prevent texture distortion during demolding.
