Which laser suits dumbbells & gym equipment
For chrome steel, stainless steel, a Fiber laser (1064 nm) is the usual choice. A fiber laser works at a wavelength that metals absorb well. It marks stainless steel, brass, aluminium, anodised aluminium and coated metals, and many hard plastics, with a permanent mark and no consumables.
A fiber laser is not suited to wood, leather, clear glass or clear acrylic, because these materials do not absorb its wavelength well.
Setting up the job
Chrome-plated steel can be marked with fiber lasers. Round handles need rotary support.
What to check before you buy
- Material match. Confirm every material you plan to sell (chrome steel, stainless steel) with a test mark before deciding on the laser source.
- Marking area. Round parts need a rotary attachment. Check the smallest and largest diameters the rotary supports, and whether it can handle tapered parts.
- Power. A 20 W source handles most text and logo marking on steel and anodised aluminium. 30 W and 50 W sources shorten cycle time and help with deep engraving on brass and steel.
- Software. Check that the software imports vector files and name lists from a spreadsheet, and handles photo engraving if you plan to offer it.
- Fume extraction. Every laser marking job releases smoke or fine particles. Budget for a proper extractor and ventilation from day one.
- Power supply. Use a voltage stabiliser or online UPS. Unstable supply can damage the laser source and controller.
- Safety. Open galvo markers need protective eyewear rated for the laser's wavelength, or an enclosure. Never laser PVC, vinyl or unknown plastics, because some release corrosive and toxic gas.
