laser marking is widely used for automotive parts, including engine parts, electronic components, mechanical parts and body interior parts. The marking content includes production information, corporate logo, etc, and must meet clear readability, durability, minimal damage and regulatory requirements. It is crucial to choose the right laser equipment and adjust the marking parameters.
The scope of laser marking of automotive parts is very wide, and most metal and non-metal materials can be laser marked. The following are some common automotive parts that are laser marked:
Engine parts: such as cylinders, crankshafts, pistons, spark plugs, water pumps, etc.
Electronic components: such as control units, sensors, navigation systems, etc.
Automotive mechanical parts: such as brake discs, brake pads, suspension system components, tires, etc.
Body and interior parts: such as keys, housings, buttons, seat belts, etc.
The marking content on these parts usually includes production information (such as production batch number, date), corporate logo, QR code, product serial number, warning signs and instructions for use, etc.
Different types of parts may have different regulations for specific marking requirements, but in general, laser marking needs to meet the following key points:
Clear and readable: No matter how complex the marking content is, it needs to be clear, readable and not easy to blur or disappear.
Durability: The marking content needs to be able to withstand various environmental influences during the use of the car, such as high and low temperatures, friction, corrosion, sun and rain, etc., to ensure its stability throughout the entire service life.
Minor damage: Laser marking should not be at the expense of damaging the material properties or structure. In other words, the marking process should minimize the thermal effect and mechanical stress on the material to avoid changing the performance of the parts.
Compliance with regulations: While meeting the above basic requirements, it is necessary to strictly abide by the relevant provisions of national laws and industry standards. For example, some parts may need to be marked with specific warning signs or instructions.
Therefore, when performing laser marking, in addition to selecting the appropriate laser equipment, it is also necessary to adjust the marking parameters according to the specific marking requirements and material characteristics to achieve a good marking effect.
