Laser coding and marking technologies have seen significant growth over the years. According to the report, the entire Laser Coding and Marking Equipment Market is expected to reach US$ 4219.9 million by 2028, growing at a CAGR of 7.8% from 2022 to 2028. Laser coders are used in several industries such as food and beverage, pharmaceuticals, and automotive due to their speed and precision in printing high-quality, indelible codes. Since the markings are permanent, they are ideal for printing essential information in packaging and barcodes to identify the products.
If you are a manufacturer, laser coding and marking machines are beneficial for your business. They can print high volumes that lead to productivity and provides traceability for your goods at the same time. If you consider investing in these equipment, it is essential to understand how to operate properly your laser coding and marking machines. This can help avoid costly errors, keep the operators safe, and maintain high-quality markings. Here are 6 frequent mistakes to watch out for and ways on how to prevent them so you can get the best results.
6 Most Common Laser Coding Mistakes and How to Avoid Them
1. Selecting incompatible material
Not all materials are appropriate for laser marking because they can cause problems like damage to the laser coding machine or the emission of harmful substances. Some fabrics burn when the heat is too strong. Denim and canvas can withstand high temperatures while heat settings must be adjusted for silk and cotton if you use them for engraving.
Consider first the qualities of the material you are going to use before you do laser coding. Some materials have differences in composition and density. Using an unsuitable substrate or material may result in irregular markings or areas with varying shades.
2. Starting the laser in the wrong spot
Mistakes happen when the laser starts in the middle. To correct this, reset the laser to its original position so it can begin working at the edge of the material where it is meant to be.
3. Incorrect alignment
A laser marking can be distorted or misplaced because of incorrect alignment. It can happen due to a loosened screw or laser head that is caused by wear and tear. Check your machine to locate the misalignment issue. Ensure that the material is properly placed in the laser coding machine so the markings are produced in the right position.
4. Design errors
Mistakes like overlapping designs affect the quality of the markings which is caused when the laser coding machine does not operate smoothly. To ensure that the design is free of errors, utilize the suitable travel speed when you move the laser above the material, especially in areas with curves or little details. Adjust the power and speed settings to prevent damaged markings.
5. Not running sample testing
The lines produced are either too dark or too light. This is why it is vital to test the material first to assess what laser settings produce the right results for your coding needs. Do not forget to conduct sampling tests on similar materials when you perform laser coding. Make the necessary adjustments to the settings to match the characteristics of the material to be marked.
6. Improper maintenance
Your laser marking machine does not function correctly the way it used to. If a drop in performance happens, then it is time to have the machine checked. Like other equipment, laser coders need regular maintenance so they can function properly. Cleaning the lens is one way to avoid mistakes in the marking process.
