How to choose the power of laser marking machine

The core factors of power selection: processing material, marking depth, production efficiency

Processing materials：

• Metal Processing: 20W-30W fiber lasers are suitable for most marking needs, while 50W and above are suitable for deep engraving or highly reflective materials (such as copper and silver).
• Non-Metal Processing: 30W-60W CO2 lasers are suitable for wood and leather, while 100W and above can also handle cutting.
• Precision Processing: 3W-5W UV lasers are suitable for plastics and glass, while 10W and above are suitable for higher speeds or depths.

Marking depth

• Small businesses or self-employed individuals: 20W fiber or 30W CO2 lasers are sufficient, priced between 20,000 and 50,000 yuan, for superficial marking (e.g., gifts, part numbers).
• Industrial users: 50W-100W fiber or 60W-100W CO2 lasers, priced between 50,000 and 150,000 yuan, are suitable for high-volume deep engraving or cutting.
• Precision industries (e.g., chip manufacturing): 3W-5W UV lasers, priced between 100,000 and 200,000 yuan, offer shallow depth but high precision.

Production efficiency

• Small batches or customized applications: 20W-30W fiber or 30W CO2, with moderate speeds, can meet daily production of 1,000-5,000 pieces.
• Large-volume production (e.g., electronics factories): 50W-100W fiber or 60W CO2, marking dozens of pieces per minute, doubling efficiency.
• 
  Ultra-high precision (e.g., medical devices): 5W-10W UV laser, slightly slower but superior quality.

Budget and Cost

• If you have a limited budget: Choose a 20W-30W fiber or 30W CO2 laser for high cost-effectiveness and a quick payback period (1-2 years).
• If you have a sufficient budget: Choose a 50W fiber or 10W UV laser for long-term, high-load production.
• Avoid low-price traps: Off-brand equipment may use inferior laser sources , resulting in a short lifespan and poor performance.
