Surface finishes may be precision ground, unpolished, coated, polished, brushed, bright, or reflective. Plastic selection is generally based on the properties of tensile and impact strength, wear resistance or hardness, chemical resistance, electrical insulation, flame retardance, static control, surface finish, and machinability. The laser power has a great influence on cutting thickness, cutting speed, cutting width and cutting quality. This material can be laser cut up to a thickness of 8 millimeters. The ablation rate of sintered polytetrafluoroethylene (PTFE) targets has been investigated as a function of wavelength within the range $193 \le \lambda \le 1064$ nm and pulse durations $5 \le \tau _{l} \le 25$ ns by means of various different lasers. When the laser beam touches the surface of the material, it heats it up to the point that it melts or vaporizes. PTFE is a difficult material to ablate with the single-photon absorption mechanism of nanosecond-pulsed lasers. In contrast, the multi-photon absorption mechanism of femtosecond pulsed laser facilitates rapid depolymerization and ejection of molecular fragments. Under certain plate thickness and cutting speed, there is an optimal range of laser power. A subset laser machinable plastics are listed below.

Teflon is heat resistant material that has many uses in various industries. The materials used by us to produce these gasket comprises … Which materials are not suitable for laser cutting and engraving? A laser system may remove material completely from the top to the bottom surface (commonly be referred to as " laser cutting "), or it might partially remove material from the top of the material down to a specified depth (commonly referred to a "laser marking"). Back To Polymers. ( see Fiberglass ) Fiberglass Emits fumes It's a mix of two materials that cant' be cut. Teflon has a large temperature reach from -200 degrees Celsius to 260 degrees Celsius. A CO2 laser can't cut it, and the resulting burned mess creates toxic fumes ( like cyanide! PTFE’ slippery surface is excellent for chemical resistance and extreme temperatures. The plates usually have a dimension of 1200 millimeters by 1200 millimeters. The plates usually have a dimension of 1200 millimeters by 1200 millimeters.
