Brake pads

Modern automotive manufacturing demands ever-greater precision, traceability, and adaptability—from prototyping to high‑volume production. Laser processing technologies—marking, welding, cutting, and cleaning—meet these needs by delivering non‑contact, high‑speed, and programmable solutions. Han’s Laser’s comprehensive portfolio empowers OEMs and Tier 1 suppliers to optimize quality, throughput, and cost across a wide range of auto parts.

1.Laser Marking & Engraving: Permanent Identification with Maximum Clarity

Key Applications

Car Labels & Nameplates

Laser marking on branded labels and metal nameplates ensures each part bears an indelible logo, part number, or warning sign.

Automotive Glass

3C certification marks, safety warnings, and serial data can be directly engraved on windshields and side windows without compromising clarity.

General Auto Parts

High‑contrast 2D codes, batch numbers, production dates, and decorative patterns on components such as shock‑absorber housings, filter housings, and interior trim.

Advantages

Non‑Contact Process

Avoids mechanical stress or deformation on delicate parts.

High Resolution & Contrast

Fine fonts, logos, and dense data matrices are crisply defined for reliable scanning and human readability.

Broad Material Compatibility

Works on metals, plastics, glass, and coated surfaces—ideal for mixed‑material assemblies.

Full Traceability

Every part carries permanent, tamper‑proof identifiers that facilitate quality control and regulatory compliance.

Recommended Equipment

• Fiber Laser Markers (MOPA & High‑Speed) for deep, high‑contrast engraving on steel and aluminum.
• UV Laser Markers for heat‑sensitive plastics and coated glass.
• CO₂ Laser Markers for non‑metallic components like rubber gaskets and plastics.

2.Laser Welding: High‑Strength, Low‑Distortion Joints

Key Applications

Transmission Gears & Planet Carriers

Precision laser welding produces robust, fatigue‑resistant joints in gearbox assemblies.

Flywheel Assemblies & Ring Gears

Integrated welding of flywheel ring gear to drive plates ensures concentricity and balance.

Shock Absorbers & Sunroofs

Welding of absorber bodies, piston rods, and sunroof frames with minimal heat‑affected zones.

Filters & Other Housings

Hermetic sealing of oil filters, fuel filters, and cabin air filter housings for leak‑free performance.

Advantages

Minimal Heat Input

Reduces warping and preserves material properties around the weld seam.

Deep Penetration

Enables single‑pass welding on parts up to 12 mm thick with full‑penetration fusion.

Clean Process

No filler metal required and minimal spatter, cutting post‑weld cleanup time.

Automation‑Ready

Seamlessly integrates with 6‑axis robots, collaborative arms, and CNC gantries for fully automated cells.

Recommended Equipment

• 2–6kW Fiber Laser Welding Systems equipped with wobble‑welding heads for wider seam tolerance.
• Handheld Laser Welders for maintenance, field repairs, or low‑volume runs.
• Wire‑Feeding Laser Modules to enhance gap‑bridging capability and joint aesthetics.
• Collaborative Welding Robots that adapt to varying part geometries.

3.Laser Cutting: Flexible, Burr‑Free Edge Quality

Key Applications

Airbag Components

Precise laser cutting of textile airbag fabrics and retaining rings to strict safety tolerances.

Automotive Sheet Metal

Cutting body panels, door reinforcements, battery trays, and interior brackets with clean edges.

Trim & Structural Parts

Profile cutting of chassis pipes, reinforcement tubes, and interior trim panels.

Advantages

Exceptional Edge Quality

Smooth, oxide‑free edges that eliminate secondary deburring.

Complex Geometry & Tight Tolerances

Software‑driven nesting and tool‑path generation adapt instantly to new designs.

Material Efficiency

Optimized nesting maximizes yield; no expensive tooling means quick prototyping.

No Physical Die Wear

Consistent cuts over millions of cycles, ideal for both small and large batch sizes.

Recommended Equipment

• HF EXPERT Fiber Laser Cutting Machines for plate thicknesses from 0.5 mm to 60 mm.
• Profile &  Tube Laser Cutters specialized for round, square, and custom‑profiled automotive tubing.
• CO₂ Laser Cutters for composite and plastic trim components.

4.Laser Cleaning: Non‑Destructive Surface Preparation

Key Applications

Pre‑Weld Cleaning

Removal of rust, oxides, paint, and oil from transmission housings, shock absorbers, and chassis frames before welding.

Paint & Coating Removal

Stripping coatings from battery trays or enclosures prior to re‑coating or marking.

Remanufacturing & Maintenance

Cleaning used parts such as brake calipers or suspension components for refurbishment.

Pre‑Bonding Surface Activation

Preparing bonding zones on sunroofs, lights, or EV modules for optimal adhesive strength.

Advantages

Dry & Eco‑Friendly

No solvents, chemicals, or blasting media required.

Selective & Precise

Only removes unwanted layers while preserving the base material.

Minimal Maintenance

Compared to sandblasting, there’s less equipment wear and no media handling.

Automation‑Friendly

Easily paired with robot arms, gantry systems, or handheld operation.

Recommended Equipment

• Handheld Laser Cleaners (50W–3000W): Suited for in-field service or flexible prep.
• Robotic Cleaning Stations: Ideal for high-volume, repeatable cleaning zones.
• Pulse or CW Laser Modules: Selectable based on surface type and cleaning depth.
