Here is difference between 20w, 30w and 50w 100w 30w is more durable than 20w , and 100w is more durable than 50w
if marking same content on same materials, 100w marking speed is faster than 20w/ 30w /50w
if marking same depth on same material, 100w marking time is shorter than 20w/ 30w /50w
Detailed Application
The 20W machine is mainly used for surface marking of plastic, stainless steel, aluminum and so on.
If the customer wants to engrave deeply, then a 30W machine will be a better choice. For all materials, aluminum is the easiest to achieve deep engraving, 30w machine will be a better choice.
If you want to do deep marking on brass,silver, or gold or cut it, you need to choose the 50watt/100w. As you know, these materials are high-reflective materials.
