Extraordinary Precision

The specifications for medical equipment and devices (including those permanently implanted in the body) call for an extraordinary level of precision and cleanliness. Microscopic welds, cycle lives in the millions, and uncompromising performance are part of your daily reality—with human lives depending on you. Our team helps medical innovators deliver groundbreaking solutions that save lives—while meeting the economic realities of today’s healthcare market.


We develop new products (and reimagine conventional ones) for surgical equipment, medical devices and sub-components such as pumps, bellows reservoirs and more. We design for extremes of lifetime use and reliability—especially when high lifecycle, zero leakage, maintenance-free operation, and high performance are essential. Our process is fast and efficient, with full in-house resources, including: 3D solid modeling (rapid proof-of-concept), finite-element structural analysis, flow simulation and sizing—along with all required qualification and documentation to meet global medical manufacturing standards.

Fabrication & Testing

We bring our innovative designs to life in an advanced manufacturing facility where state-of-the-industry processes are executed under the highest standards. Seasoned technicians supervise advanced fabrication in:

  • Metal joining & forming with vacuum furnaces, and hydraulic presses to 1200-ton strength
  • Precision welding including methods such as TIG, laser, and electron-beam
  • Metal finish & metallurgy, with two automated cleaning lines featuring advanced cleaning, passivation and etching capabilities
  • Functional testing, including extreme environmental chambers, spring, tensile, and acceptance testing. Performance validation for all parameters.

High precision/low cost sampling pump

Our customer—a large medical equipment manufacturer—required a new design for a precision metering pump for blood analysis sampling. The component was to be used in a disposable cartridge, so relative cost was an issue.

Critical tolerances, Bio- and chemo-compatibility

Extreme demands for reliability, precision, and absolute seal were matched by the already strict regulatory requirements for biocompatibility and compatibility with the drugs the new system was dispensing within the body.
