Katech maintains a full-service CNC facility that provides one-off designs and small runs of prototypes that assist corporate clients with design revisions, functionality, and cost-reduction strategy.
Katech can build from metal, plastic, or composite materials. We are known for quick turnaround and extreme quality.
Katech CNC resources include a Brute 3124-V 5-Axis VMC; a Fadal 15XT-4-Axis VMC; a Fadal 4020-4-Axis VMC; a Haas VF2-SS-4-Axis VMC; and a Haas SL-20- Lathe, with bar feeder and live tooling.
Katech provides short- and long-run manufacturing services delivering engine and vehicle components to the most demanding specifications. Whether it’s a thousand parts or a hundred thousand – from simple piece parts to complex prismatic parts requiring four- and five-axis machining – Katech manufacturing consistently delivers on time and to the highest level of quality.
Katech provides OEMs engine development and testing solutions that can significantly reduce product development time and cost.
Katech’s rigorous assembly process covers pre-assembly measurements, clearances, assembly procedures, torques, adhesives, lubricants and other aspects of engine assembly. Traceable records are maintained for future reference. Quality control is maintained through progressive inspection and procedures.

Dynamometer durability testing and track simulation
Engine calibration (MEFI4)
Katech maintains three Engine Dynamometers Cells geared for performance applications. Two are rated over 12,000 RPM and 1000 horsepower, the third cell is rated at 10,000 RPM and 800 horsepower. All cells operate with multiple fuels, allowing calibration over a wide-range of applications.
The Katech Motoring Cell measures parasitic losses for a range of engine components. The Katech Valvetrain Cell provides physical testing, from cam to valve actuation. The Katech Fuel Flow Cell tests fuel system configurations prior to first application.
The six test cells are also used to provide several other critical engine tests, including cylinder pressure and engine air flow.
