High-Precision Electrical CD Pattern Round Knobs: Custom Injection Molding Solutions
To meet the demand for precision operational components in household appliances, smart electronics, and other industries, we offer custom injection molding solutions for high-precision electrical CD pattern round knobs. By integrating CD pattern technology with round knob structures, our tailored solutions address both functional and aesthetic requirements across diverse electrical scenarios.
CD Pattern Customization: Adjust spacing (0.08-0.5mm), depth (0.02-0.1mm), and density based on electrical design specifications. Supports continuous concentric circles or segmented patterns, balancing anti-slip texture and reflective decoration.
Mold Precision Guarantee: Cavity surface roughness Ra ≤0.03μm, ensuring 99% clarity of CD patterns on molded round knobs with no burrs or edge collapse—meeting IP65 dustproof and waterproof standards for electrical products.

Scenario-Specific Custom Solutions
Kitchen Appliances: For high-temperature and oil-contaminated environments, we use S136 corrosion-resistant mirror steel molds. A CD pattern spacing of 0.2-0.3mm ensures anti-slip operation while facilitating daily cleaning. Molded knobs pass 100,000 rotation tests (5N load) with 98% CD pattern retention, compatible with high-temperature plastics like ABS/PC.
Smart Home Appliances: Combining etching-filling technology, mold surfaces feature CD pattern grooves (0.15-0.25mm spacing) filled with high-transparency epoxy resin, enabling knobs to achieve "matte metallic finish when powered off + glowing CD patterns when powered on." Molds are compatible with two-shot injection parameters (e.g., PMMA melting temperature 230-250°C, TPU holding pressure 50-70bar) for tight bonding between light-transmitting layers and substrates.
Commercial Electrical Equipment: To withstand frequent operation and harsh environments, cemented carbide (WC-Co) molds are used. A CD pattern depth of 0.05-0.1mm enhances wear resistance, allowing knobs to endure 500,000+ presses with no significant pattern wear. Mold surfaces undergo special treatment to resist repeated wiping with 75% alcohol, meeting disinfection requirements for medical devices.
Advantages of Our Custom Services
End-to-End Custom Response: Deliverable from 3D drawing analysis to mold trial within 7 business days, supporting small-batch trials (0-20 units) and mass production scaling (800 units/batch).
Flexible Process Matching: Customize optimal process combinations based on production volume, budget, and performance needs (electroforming for mass production, CNC + laser engraving for small batches), reducing trial-and-error costs by 30%.
Lifecycle Support: Provide mold maintenance manuals (including pattern repair solutions) and injection parameter guidance (e.g., melt temperature, holding pressure) to ensure ≥99.5% consistency of CD patterns during mass production.
