Laser Cut Hdpe

Cutting of polyethylene can be performed with a co 2 laser to produce a clean non discolored cut with a slight raised edge near the point of ablation.

Laser cut hdpe.

In particular acrylic is ideally suited to laser cutting. It loves to burn so watch out. Molten plastic on the surface each side of the cut can be a problem particularly if the air assist blows it around. The materials that the laser can cut materials like wood paper cork and some kinds of plastics.

The materials that the laser can cut materials like wood paper cork and some kinds of plastics. It melts rather than vaporizing and it tends to hold enough heat that the parts fuse back together after the laser has passed by. It can be efficiently cut by laser but it recedes slightly during the cut kerf is relatively wide. However due to the relatively low.

Pe foam comes in a variety of thicknesses compressions and colors. Hdpe is cut resistant and milky white in color. Etching can be done on almost anything wood cardboard aluminum stainless steel plastic marble stone tile and glass. Safe materials the laser can cut or etch.

Hdpe melts rather than cuts and i needed a lot of air assist to remove the melt then the final cut looked a bit like it had been cut with a plasma torch. Etching can be done on almost anything wood cardboard aluminum stainless steel plastic marble stone tile and glass. Hdpe is similar to candle wax. Like most thermoplastics the heat generated while you are cutting it will cause the plastic to melt and fuse together behind.

High density polyethylene hdpe is a versatile fda and usda approved food grade plastic. I chalked this up as a failure and decided hdpe and lasers are not good friends. Polyethylene does not readily absorb the energy of a 1 06 micron fiber laser. Laser engraving and laser marking of polyethylene are possible using a co 2 laser.

The laser can cut or etch. Consider masking tape but unless it sticks to the plastic really well then pull it all off again as loose tape encourages fire. All plastics cut with a smooth clean and burr free edge. Another effect is slightly darkened edges as a result of the laser beam.

You could have a hdpe cutting board in your kitchen. As the focussed laser beam slices through the plastic the edge re solidifies immediately after being vaporised and often a glassy edge is the final result. Laser cutting of polyethylene.
