Why plexiglass and acrylic material can be cut by laser machine without melting edge, but cutting PPC material will be fused edge and not easy to cut off once. What material cost is low and can be cut with laser machine
Organic glass, acrylic material relatively high melting point, >200 C, light touch material after rapid warming, solid keep a relatively long period of time, the laser energy absorption rate, temperature close to the melting temperature, and soon reached the vaporization effect separately, so the cutting effect is ideal.
PPT material, Chinese name chlorinated polypropylene, relatively low melting point, about 50 degrees, so when cutting, laser material contact melting rapidly become sticky, the light absorption rate decreased due to conduction and low melting point, touch around the spot began to melt, adhesion, cementation, the cutting effect is not ideal.Therefore, the effect of laser cutting depends partly on the laser, and the other depends on the composition of the material being cut. The effect of the cutting is necessarily different.Hope to be of some help to you.
Let me answer.First of all, the principle of laser cutting is the laser with high heat, especially the laser focus, the maximum energy is concentrated, in the face of workpiece to be cut, from high heat to make light touch parts instant vaporization / carbonization, allowing the material to touch the spot line is divided into two parts, finished cutting process.
