Marking in the Automotive Industry

The ease of automating laser marking systems and integrating them into the production chain shows them to be unmatched in throughput and cost per part. CMS Laser systems are currently in use marking automotive interior plastic parts, steering column stalks, gauges, radio/temperature controls, window switches, key fobs, and suspension parts. They also mark components in the headlight/taillight assemblies, and various parts under the hood of today’s cars.

Automobile part marking provides necessary information to drivers, mechanics, vendors, suppliers, and employees on the line. 2D codes, barcodes, serial numbers, compliance details, and informational and warning material for car owners can be found throughout the car.

Automotive Marking Methods

Laser marking in automobiles comes by several methods today. Plastics make up approximately 50% of today’s cars, and marking the many different plastics requires different ways to go about it. Ablation is used to expose clear or translucent areas for backlighting, where foaming or charring might mark the diagram on a fuse panel cover. Metals are nearly as varied as alloys become the norm, and they might be marked using oxidation, ablation, or layer removal. Even tire marking via laser is common today.

Automotive Etching

CMS Laser is a leading global supplier of CO2 laser glass etching technology, including our patented handheld etching laser system (see our Client List). We design and build industrial turnkey and custom laser systems for etching and engraving automotive glass, metal, plastics and more.

We have developed the state-of-the-art handheld etching system available today. With a small footprint, able to be truck mounted, and a lightweight CO2 laser “gun”, it makes marking serial numbers, VINs, and much more very simple. The handheld laser is equipped with suction to pull it tight against the marked part, ensuring proper focus and a high quality mark every time.

Advantages of Laser Etching in the Automotive Industry

The advantages of laser etching over conventional methods are significant. The laser requires no consumables and leaves no residue or hazardous material to clean up. No masking is required, and sequential data can be accessed on the fly from mainframe or server databases. Changes to trademarks or images are just a few keystrokes away. DXF or PCX formatted graphics can be imported directly into the system and CMS Laser’s LaserGraf© software lets you switch between standard or reverse image etching within seconds.

We will supply you with a no cost to you complete report on the technical feasibility of your particular application. We will also include information about the level of performance you can expect with your system.

Automotive Welding

The automotive industry has become one of the most visible uses of laser welding technology. Virtually no car built in the last 20 years has not been constructed in some part without it. Whether frame and body welds, drivetrain components, or plastic welds on a variety of parts, CMS Laser’s systems provide welding solutions from bumper to bumper.

Advantages of Laser Welding in the Automotive Industry

The growing use of high strength steel and aluminum has driven new advances in laser welding, allowing for an increasing number of alloys to be welded. Both butt/seam welds and lap joint welds can be accomplished without the use of filler material, with low heat transfer beyond the weld zone, and at high speeds. Our systems outperform traditional methods for deep penetration and heat conduction welds in speed, precision, weld quality, and cost of operation.

Plastic welding has grown in capability tremendously over the past 10 years, allowing plastics that resisted other forms of adhesion to be joined with high strength and durability properties. Each advancement has gained significant ground on broad usability in manufacturing. These include reduction of doping requirements, additives that increase absorption rates, and the ability to weld clear on clear plastics.
