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.

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.
