Core Customization Parameters & Precision Control

Custom Size Range: Diameter 5-50mm, thickness 1-8mm, supporting specialized round knob structures (e.g., stepped, flanged). Coaxiality error ≤0.01mm ensures precise assembly.
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.
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.

Scenario-Adaptable Parameter Comparison

Application Scenarios	Typical Products	Mold Material	CD Pattern Parameters	Key Performance Indicators	Applicable Processes
Kitchen Appliances	Coffee machine, oven knobs	S136 mold steel	0.2-0.3mm / 0.05-0.08mm	Temperature resistance: -30°C to 120°C; 100,000 rotation cycles	Electroforming/CNC + Laser Engraving
Smart Home Appliances	Air purifier, floor cleaner buttons	Etched steel + epoxy resin	0.15-0.25mm / 0.03-0.06mm	Light transmittance ≥92%; compatible with two-shot injection	Etching-Filling
Commercial Electrical Equipment	Medical device knobs, industrial controllers	Cemented carbide (WC-Co)	0.08-0.2mm / 0.05-0.1mm	Wear resistance ≥500,000 cycles; chemical resistance	Electroforming

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.

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."

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.
