Technical Specification Marking

工程参数永久蚀刻 · PCD · ET Offset · Center Bore · Load Rating · JWL / VIA Compliance

Permanent laser-etched or CNC-machined technical parameters engraved along the outer rim flange, stepped lip shelf, or valve stem perimeter. Clearly identifies dimensional engineering specs, load carrying capacity (kg), and regional homologation symbols for frictionless vehicle inspection, MOT/TÜV compliance, and motorsport scrutineering.

TECHNICAL DELIVERABLES & FEATURES

Explicitly denotes Wheel Size (e.g., 20x10.5J), PCD (e.g., 5x112), and ET Offset (e.g., ET32)

Permanently marks Wheel Load Rating (e.g., 950 KG / 2094 LBS) conforming to JWL/VIA standards

Includes mandatory safety certification stamps: JWL, VIA, or regional conformity codes

Eliminates paper certificate dependency during technical roadworthiness inspections

ENGINEERING DISCIPLINE COMPARISON

Fiber Laser Etch vs CNC V-Carve vs Paint Infill

Different engraving methods serve distinct aesthetic and mechanical purposes. We offer 3 precision techniques to match your desired finish contrast, tactile depth, and regulatory requirements.

DISCIPLINE 01

1064nm Fiber Laser Etching

光纤冷激光表面微米级蚀刻

Depth:0.01 mm – 0.05 mm (Non-Structural)
Tooling:Solid-State Pulsed MOPA Fiber Laser (1064 nm)
Aesthetic:Clean Matte Dark Contrast or Bright Silver Anneal

A non-contact thermal micro-oxidation process that modifies the surface layer without removing structural material or compromising forged rim flange fatigue life.

›Sub-micron 0.03mm focal spot captures hairline details and micro-scripts down to 1.5mm font height
›Zero mechanical cutting force; generates zero micro-cracks or stress concentrations on rim flanges
›Can be applied directly over cured powder coats, candy clearcoats, or raw brushed metal surfaces
›Highly resistant to high-pressure wash chemicals, road salt, and harsh brake cleaning solvents
Recommended Engineering Scope:Fine technical specification markings, complex brand logos, and serialized hub UID codes.
DISCIPLINE 02

5-Axis CNC V-Carve Mechanical Engraving

五轴刀具三维倒角几何雕刻

Depth:0.30 mm – 0.80 mm (Three-Dimensional)
Tooling:High-Speed Spindle (24,000 RPM) + 60°/90° Diamond Micro-Endmill
Aesthetic:Prismatic Facets Catching Sunlight & Raw Billet Highlights

A mechanical cutting method using precision angled diamond endmills to carve deep, beveled V-grooves into the solid 6061-T6 aluminum rim flange.

›Carves authentic three-dimensional beveled facets that catch ambient light and gleam like jewel facets
›Reveals the raw, high-luster forged aluminum grain beneath painted or tinted clear coatings
›Substantial tactile depth that can be felt by hand, exuding pure mechanical craftsmanship
›Ideal substrate for subsequent hand-enamel paint filling or contrasting anodizing
Recommended Engineering Scope:Stepped rim lip branding, retro vintage wheel re-creations, and bold custom signatures.
DISCIPLINE 03

Hand-Poured Enamel Paint Fill

手工填漆与紫外线高分子固化

Depth:Flush Infill Level (Over CNC V-Carve Trough)
Tooling:Polyurethane Automotive Enamel + UV Curing Oven
Aesthetic:Vibrant Color Contrast Matched to Brake Calipers or Paintwork

Precision CNC-machined grooves are meticulously hand-filled with high-grade automotive polyurethane enamel, then baked in thermoset curing ovens for permanent adhesion.

›Custom color formulation matched exactly to vehicle paint codes, Brembo calipers, or interior leather
›Filled flush with the rim surface and sealed beneath protective UV-absorbing ceramic clearcoats
›Resistant to brake dust etching, wheel acids, and thermal cycling up to 180°C
›Produces a striking high-contrast pop against dark brushed, satin black, or polished rim lips
Recommended Engineering Scope:Contrast brand badges, colored numbered edition insignias, and performance accent lines.
METALLURGICAL PERMANENCE

Zero Micro-Fissures. 100% Structural Integrity.

Unlike amateur hand-punched stamps or aggressive deep engraving that creates dangerous micro-crack initiation sites on thin rim lips, BOYAO uses finite-element-verified engraving safe zones. Our MOPA cold fiber lasers induce zero heat-affected zone (HAZ) embrittlement on aerospace 6061-T6 forgings.
