Gateway is a leader in the field of precision micro machining. It specializes in the processing of highly precise components requiring extremely close tolerances, such as micro holes for catheters, flow orifices, micro filters, masks, grids, gaskets, channels, flex circuits, epoxy preforms, piezo electronics, micro wire stripping, marking, etching, etc.

It is located in the St. Louis MO area, permitting efficient servicing of customers across the US.

Gateway Laser Services uses customized equipment operating in five different wavelengths in the IR, Green, and UV spectrums, and is accustomed to solving challenging applications. Eximer UV technology allows material ablation (shaving) of polymer materials in single micron (0.00004") increments.

With low setup costs, the process is suitable for prototyping to mid volume production quantities.
