Stencils Unlimited specializes in precision laser manufacturing. We use advanced Infrared (IR),
(UV) and Carbon Dioxide (CO2) laser technology to cut thin and ultra-thin materials such as metals and
plastics. We offer a variety of laser processing services as well as prototyping and micromachining with
tolerances as low as +/- 2um.
Please see laser technology and materials.
Laser processing offers accurate, clean and flexible ways to develop solutions for a wide variety of materials. The laser beam can cut with high precision the most detailed features without burning or warping the surrounding areas. Here is a list of the most important benefits of precision laser cutting.
Infrared systems are typically used for to fabricate precision metal parts. Similar to a cutting torch process, the laser heats up the metal to a molten state and high-pressure air blows away the molten material leaving a smooth edge.
With the ability to focus the beam down to 25um spot sizes and the extreme accuracy of the motion systems metals up to .020" thickness can be processed with ±001" or better tolerances.
Ultraviolet lasers achieve minimal heat-affected zones since it uses ablation instead of melting the material. The quick laser pulses eliminate the material so fast that the surrounding material absorbs very little heat. This type of precision laser cutting systems are typically used in non-metal parts but also can be used on very thin metals that require ultra-fine details, a necessity for no contact cutting or special requirements for handling.
With this technology the cutting is achieved by melting or vaporization of the material. For this process, an electric current is discharged through a gas to produce a laser. The Co2 lasers allows to process thicker metals, fired ceramics and acrylic type materials that would otherwise burn, melt or not cut with UV or IR laser systems.
