Applicable Laser Marking Materials

How to consider the design of workpieces with marks that require laser marking?

When designing a workpiece that needs laser marking, the following aspects need to be considered.

Material selection: Materials suitable for laser marking need to be selected. In general, metals, plastics, ceramics, glass and other materials can be laser marked. However, the characteristics of different materials are different, and the marking parameters need to be adjusted accordingly.

Design pattern: a suitable marking pattern needs to be designed. The design needs to consider the pattern size, shape, font and other factors to ensure that the marking effect is clear and visible. If the marking is text or image, it needs to be converted to vector format.

Marking position: The marking position needs to be determined. Generally speaking, the marking position needs to consider the aesthetics and usability of the workpiece. The marking position should avoid conflict with the functional parts of the workpiece, so as not to affect the use of the workpiece.

Marking parameters setting: need to set the appropriate marking parameters according to the material and design requirements. Mainly including laser power, scanning speed, focal length, laser point spacing, etc. Different materials and patterns require different parameter settings, which need to be adjusted experimentally.

Safety considerations: laser marking is a high-energy light source, and requires attention to safety during operation. Protective glasses need to be worn to avoid direct observation of the laser. At the same time, the laser marking equipment needs to be placed in a safe location to avoid harming personnel and equipment.

In short, when designing the workpiece to be laser marked, all factors need to be considered to ensure the marking effect and quality, while paying attention to safety issues. If needed, professional help and support can be sought.

The operation steps of laser marking on workpiece?

The operation steps for laser marking on the workpiece are generally as follows.

Prepare the workpiece: Place the workpiece to be laser marked on the marking table and make sure the surface of the workpiece is smooth, flat and free of impurities.

Design the marking pattern: Use computer-aided design software to design the pattern, text, 2D code and other information to be printed on the workpiece, which can be typeset, adjusted and edited as needed.

Set marking parameters: According to different materials and marking requirements, set the appropriate marking parameters, including laser power, frequency, scanning speed, focal length and other parameters, as well as the movement range of the table.

Adjust the laser head position: align the laser head to the workpiece surface and adjust the proper distance and angle to ensure the laser beam irradiates to the workpiece surface normally.

Start marking: Start the laser marking equipment, send the marking pattern to the equipment control system, and control the laser beam for marking operation on the workpiece surface.

Observe the marking effect: observe the marking effect in real time and adjust the marking parameters and position until it meets the requirements.

Inspect and package the products: After finishing the marking operation, inspect and package the products to ensure the product quality and integrity.

It should be noted that different workpieces and materials have different requirements on the parameters and operation steps of laser marking, so you need to understand and master the characteristics and requirements of the relevant materials and marking technology before laser marking in order to develop suitable operation steps and parameters. At the same time, before laser marking, you need to strictly comply with the relevant safety regulations to avoid harm to the human body and equipment.

Frequently asked questions about laser marking of workpieces?

Common problems and solutions for laser marking of workpieces?

Insufficient or too deep marking depth: This is usually caused by improper setting of marking parameters. You need to readjust the laser power, scanning speed, focal length and other parameters to achieve the proper marking depth.

Blurred or distorted marking pattern: This is usually caused by improper adjustment of the laser head position or unreasonable marking parameters. The laser head position and marking parameters need to be readjusted to ensure that the marking pattern is clearly visible.

Marking position offset: This is usually caused by uneven surface of workpiece or inaccurate laser head position. The laser head position and the moving range of the table need to be readjusted to ensure the marking position is accurate.

Slow marking speed: This is usually caused by insufficient laser power or slow laser head movement speed. The laser power and moving speed need to be readjusted to improve the marking speed.

Uneven marking effect: This is usually due to uneven surface material of the workpiece or improper marking parameters settings. Need to readjust the laser power, scanning speed and focal length and other parameters to ensure uniform marking effect.
