Laser Marking Machines in Automobile Industry

The automotive industry is vast, has employed millions of experts from across the world, and has impacted millions of people. The industry caters to everything from the building and development of automobiles to marketing and maintenance. While its major usefulness is in the commercial sector, it also serves other purposes like military vehicles and transport trucks.

Started in 1980, the automotive industry has experienced rapid development over the decades. According to research, the world has now recorded roughly 1.015 billion motor vehicles, with more than 70 million cars being sold out annually.

The automotive is a huge industry that impacted us in many ways. Be it the automobile cars that we use or the public transport we take, this ever-growing industry has and will continue to change the world.

The industry continues to develop, and there has been an ongoing focus on developing new ideas like creating self-driven cars. And even while waiting for these new inventions, the industry never relents at creating a faster, efficient, and more affordable process that will not be sacrificed for safety. The automotive industry has always prioritized safety in its production.

Today, automobile companies have individual parts components that serve different purposes. That’s why product traceability is exclusively vital in the automobile industry. Hence, automotive components come with a means of identification, such as a QR code, Barcode, or DataMatrix. With this code, you can easily trace the manufacturer of a component, the production date, and the production location. This way, you can easily manage any manufacturing error.

The most effective way to trace a component is through laser marking. It does not matter whether the component is made of metal or plastic, as the marked surface is permanent and visible.

Part marking is an integral aspect of the automobile manufacturing process. With thousands of parts fabricated and designed to assemble automobile products, we need a reliable part marking machine to ensure that the parts are correctly delivered and installed.

From seats to tires to bolts and wheels, each part of an automobile comes with its unique part numbers that determine their location and function on the assembled automobile product.

Laser mark codes and how they are applied

There are several laser marked codes. What are they and how are they applied? The automated manufacturing sector relies on barcodes to determine the parts that will be grouped to a particular section of the assembly line.

One of the best ways to tag parts of a vehicle is to use a laser marking machine. These machines work like a labeling machine- it uses laser beams to create an identity on the surface of a manufactured product.

Be sure not to confuse the process with laser etching and laser engraving- laser marking is a non-intrusive method of marking the part of an automobile product.

Unlike laser engraving and laser etching that digs deep to takes off material from a surface, laser marking modifies the surface and discolors the specified part of the material. That discoloration is the text and barcodes you see on car parts.

Laser marking machines uses lasers to heat up the parts for marking. The lasers then oxides the surface and change it into a color that is different from the initial surface material. Laser marking is commonly used on titanium and steel materials. However, they are also used to mark materials like glass and polymers.

Laser marking- applications in the automobile industry

Laser marking machines are essentially useful in the auto industry, and for several reasons. Here are they:

1. Part numbering for components of the engine

Engineers use sophisticated alloys of steels to make the engine components of cars (these steels can withstand harsh conditions). They then use QR codes to label parts that are known to endure harsh conditions. Apart from its usefulness during car assembly, these machines are also useful when repairing or maintaining a car.

Even after many years of using a car, mechanics can still recover engine blocks and crankshafts, as well as retrieve the numbers and codes that were initially printed on the parts during production.

Laser marking with barcodes and part numbers are also done on Bearings, bolts, and nameplates on the engine bay. Paper stickers cannot withstand the harsh conditions of the engine bay-lubricants, and heat present inside it will dissolve the paper blends.

Once the part’s surface is laser marked, these labels will never be dissolved and removed by adverse conditions, unlike with ink and paper stickers.

2. Circuit boards

Electronic components often use printed circuit boards, which are produced in large quantities before assembly. Engineers automatically assemble these printed circuits on a silicon board. They then use laser marking machines to trace the layouts and solder the electronic components on the circuit board to improve readability and consistent production.

3. Fuse boxes

Fuse boxes, found in the cabin and on the engine bay, usually have their covers printed with layouts and diagrams. This ensures that the mechanics and car owners are guided on which fuses operate in correspondent to the car’s electrical function.

Papers stickers and conventional ink would not last long and may need to be removed after some years of use. That’s why modern automobile technology utilizes the use of laser marking to have the guides printed on covers of the fuse box, which will last for as long as the car remains functional.

4. Instrument panel buttons

If you’ve checked your car’s instrument cluster, you will notice that there are symbols printed on the levers and buttons. These labels are created with laser marking machine. Since paints or inks are not used, these labels will last for many years and won’t fade away.

5. Body frames and panels

As with engine part numbers, part numbering systems are also required on body frames and panels during assembly. Laser machines are now used by part manufacturers to print the necessary identifying number on parts, which will help with distribution and installation. Laser marks will never damage the part’s surface. These marks can also be covered up by painting processes or metal finish application.

Back in the earlier days of the automotive industry, automotive companies generally use stickers and inks to label important parts of cars. Later on, the industry has progressed from using stickers to creating sophisticated barcodes that are usually laser marked to the processed car.

If you’re planning to buy a laser marking machine for your business or company, select a machine that perfectly supports your production line. One of the greatest issues with marking in the automotive industry is wit traceability and readability.

It is crucial for all parts of a car to be traced to its location, and that these parts must be easy to read too. That’s where the laser marking machine comes in and has become more active in recent years.

One of the best ways to tag car parts is to integrate the use of a laser marking machine. These machines work like a labeling machine- it uses laser beams to create an identity on the surface of a manufactured product. Even after many years of using a car, mechanics can still recover engine blocks and crankshafts, as well as retrieve the numbers and codes that were initially printed on the parts during production.
