Laser engraving can create intricate designs and patterns on a variety of materials. However, lasers will encounter some problems when processing special materials, such as insulating foam. Often used for thermal and acoustic insulation, the material is a complex mix of materials that is difficult to cut and engrave with a laser.Processing suggestion
According to the characteristics of insulating foam, you can improve your processing procedure from the following aspects.
- Use a high power laser engraver. To effectively cut or engrave insulating foam, you'll need a laser engraver with a high power output. This will help ensure that the laser can penetrate the foam and create clean, precise cuts or engravings.
- Select the correct machine setup. The settings on your laser engraver will play a vital role in the success of your engraving project. You'll need to experiment with different settings to find the combination that works best for your particular foam. Mainly including the power output, speed and focus of the laser.
- Use the swivel attachment. The swivel attachment can be a useful tool if you are trying to carve curved or irregular surfaces into foam.
- Use multiple processes. Since the pink insulating foam is very thick and heat resistant, multiple passes may be required to achieve the desired engraving. This means you will need to repeat the laser engraving in the same area several times to get a good result.
Insulating foam can be difficult to laser engrave compared to common laser processing materials, but the tips above can help you achieve better engraving results.
