Select based onprocessing materials(metal/plastic/ceramic, etc.),marking requirements(depth, speed, precision), and budget. For example:

• Fiber Lasers: Ideal for metals, alloys, and some plastics; long lifespan (over 100,000 hours) and high electro-optical conversion efficiency.
• CO₂ Lasers: Suitable for non-metals like wood, acrylic, and glass; lower cost.
• UV Lasers: Feature "cold processing" for heat-sensitive materials (e.g., medical supplies, electronic components) with micron-level marking precision.It is recommended to provide material samples and expected effects for manufacturers to test and recommend a solution.

• T/T (Telegraphic Transfer): Suitable for large orders; bank fees are approximately 0.1–0.3%.
• L/C (Letter of Credit): Protects both parties but has a complex process and higher fees.
• PayPal: Suitable for small orders; fast fund receipt but fees are ~4.5% + fixed charges.

• Metals (e.g., carbon steel): High power (80%), low speed (500–650 mm/s), low frequency (20 kHz), filling interval 0.05 mm.
• Plastics (e.g., ABS): Low power (30%), high speed (2000–3000 mm/s), high frequency (50–100 kHz) to avoid burn-through.
• Ceramics: High power (70–90%), low speed (300–1000 mm/s); repeat marking 2–3 times to deepen the effect.

• Optical Path Cleaning: Wipe reflective mirrors and focus lenses with a lint-free cloth weekly to prevent dust from affecting energy transmission.
• Laser Maintenance: Regularly check cooling water purity (deionized water is recommended) and replace filter elements every 6 months.
• Software Updates: Install manufacturer-provided firmware updates promptly to optimize performance and compatibility.
