When purchasing a laser marking machine, the choice of different powers is often confusing. Common laser marking machine powers on the market are 10W, 20W, 30W and 50W. These values represent the output power of the laser, which directly affects the marking effect, processing efficiency and applicable materials. The power size cannot be distinguished from the appearance, and it mainly needs to be tested through nameplate identification or professional equipment. So, what are the specific differences between laser marking machines of different powers? What is the difference between fiber laser marking machine 20W and laser marking machine 30W? How to choose? Then let's take a look together!
The impact of laser power on marking effect:
Marking depth: The greater the power, the stronger the laser energy, and deeper engraving can be achieved. The 10W laser marking machine has a lower power and is suitable for shallow marking, while the laser marking machine above 20W can perform deep processing.
1. Processing speed: Under the same material and depth requirements, high-power lasers can complete processing faster and improve production efficiency.
2. Marking format: High-power lasers usually support a larger marking range and are suitable for large-size products or batch production.
3. Power adjustment: High-power lasers can be used at lower power, but low-power devices cannot be upgraded to higher power. For example, a fiber laser marking machine 30W can be reduced to 20W, but a fiber laser marking machine 20W cannot achieve the processing capacity of a fiber laser marking machine 30W.
How to choose a suitable laser marking machine?
According to material requirements: Different materials have different absorption rates of laser energy. For example, some metal materials require at least fiber laser marking machine 20W to form a clear mark, while harder or more reflective materials may require fiber laser marking machine 30W or more.
Consider long-term use needs: If you need to process deeper marks, increase production speed or increase processing format in the future, it is recommended to directly choose higher-power equipment to avoid the subsequent cost of replacing equipment.
Budget and cost-effectiveness: The higher the power, the higher the equipment cost. Enterprises can choose equipment that meets their needs within the budget while taking into account the possibility of future expansion.
Purchase suggestions:
When purchasing a laser marking machine, you should consider processing requirements, material properties, and future production plans. Although high-power equipment is more expensive, it has more advantages in efficiency and scope of application, and is suitable for long-term development needs. For example, if you require a higher marking depth, faster speed, larger marking format, etc., you need to choose a higher-power marking machine.
