Custom Laser Cutting and Engraving Services from Teca-Print USA

Teca-Print uses the very latest Co2 laser technology in the production of its customers product. Whether we are cutting or engraving, our machines guarantee accuracy and quality.

Our CO2 lasers are a type of gas laser. In this device, electricity is run through a gas-filled tube, producing light. The tube has a mirror at both ends; one which is slightly transparent and one which is completely reflective. There are four gases used to create a mixture of carbon dioxide (CO2), hydrogen (H), nitrogen (N) and helium (He). A light (invisible to the human eye) is created by the CO2 laser which falls in the far infrared range of the light spectrum.

The gases combine with the mirrored tube to create an extremely forceful light. This light is reflected through the tube and becomes stronger due to the effects of the nitrogen. Once the light is strong enough to penetrate the partially transparent mirror it then leaves the tube creating a beam.

Laser Engraving/Cutting

The laser, controller and work surface are the three main components of a laser engraving machine. The laser serves as a sketching tool, allowing the controller to use the laser’s beam to trace patterns onto the surface. The controller controls the direction, intensity, speed of movement, and spread of the laser beam focused on the surface. The surface is chosen to match the type of material the laser can act on. The exact same machine is used for both the cutting and engraving process. Settings are altered to increase/decrease both the strength of the laser as well as the duration of time the laser takes to move across the part.

There are three main genres of engraving machines. With our machines your piece is always stationary, and the laser optics move around in two dimensions, directing the laser beam to draw vectors.

The point where the laser beam touches the surface is on the focal plane of the laser’s optical system. This point is typically small, perhaps less than a fraction of a millimeter (depending on the optical wavelength). As the light passes over the surface, only the area of the focal point will only be changed notably. The surface temperature may rise due to the energy produced by the laser’s beam.

The heat energy produced by the laser offers an effective method of material removal.

Lasers are extremely efficient when used on non-reflective materials such as plastic, wood and enamel. Cooling systems are required to counteract the heat energy produced by the laser.

The laser’s path is decided by programming the controller. A consistent material depth is achieved by programming the laser to follow a strict path while preventing the laser from hitting the same surface area more than once. Certain paths are avoided to help maintain material depth (e.g. crisscrossing). Speed, spread and intensity are all settings which can be altered to allow flexibility in the design process. Changing the duration of the duty-cycle (the length of time the laser is on for each pulse) assists in controlling the power used to engrave the given material.
