Laser Cut Hdpe Plastic

Hdpe is similar to candle wax.

Laser cut hdpe plastic. Polyethylene does not readily absorb the energy of a 1 06 micron fiber laser. Laser cutting of polyethylene. It is used for shrink packaging plastic bags piping bottles large and small containers and toys. 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.

You could have a hdpe cutting board in your kitchen. All plastics cut with a smooth clean and burr free edge. However due to the relatively low. It loves to burn so watch out.

It can be efficiently cut by laser but it recedes slightly during the cut kerf is relatively wide. Pe foam comes in a variety of thicknesses compressions and colors. 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. Molten plastic on the surface each side of the cut can be a problem particularly if the air assist blows it around.

Hdpe is cut resistant and milky white in color. In particular acrylic is ideally suited to laser cutting. Like most thermoplastics the heat generated while you are cutting it will cause the plastic to melt and fuse together behind the cutting blade.
