Laser Manufacturing Services

  • Laser Cutting

    This process is used to cut a wide variety of materials to make precision thin parts.

    Benefits:

    • Fast and low cost for prototype and short runs.
    • Extremely fine contours.
    • Clean non-contact burr free cutting.
  • Laser Drilling

    Unlike mechanical drills, laser drilling is used for accuracy and precision drilling.

    Benefits:

    • Small holes sizes and complex shapes.
    • Drill hard and soft material.
    • Smooth hole surface.
  • Laser Skiving

    This process is used to remove outer layers of material without damaging inner layers.

    Benefits:

    • Fast, precise & repeatable.
    • Consistent depth and width control.
    • Minimum part distortion.
  • Laser Marking

    This process is used to engrave marks onto the surface of a wide variety of materials.

    Benefits:

    • High Resolution, permanent mark.
    • Non-contact, low part stress.
    • Process curved surfaces.

Benefits of Laser Machining

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.

  • Lower cost than traditional machining
  • High precision and better repeatability from part to part. Perfect 90 degrees cuts.
  • Cleaner surface that does not require secondary deburring
  • Smooth aperture sidewalls
  • No stress from physical tools
  • Smaller feature sizes
  • Reduced material waste
  • Tighter tolerances
  • Minimal heat affected areas

Laser Technologies

IR LASERS

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.

UV LASERS

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.

CO2 LASERS

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.
