Neo Mechanics Limited was established in September 2011 to promote and commercialize a revolutionary high pressure seal, trademarked as Ultimate Seal™, which was invented by its Korean partner Mr. Moses Chang, a serial inventor and an expert of mechanical engineering, and jointly developed with his Hong Kong partner Mr. Stanley Ko. They have applied for more than forty patent applications worldwide, of which nine certificates have been granted: two in America, two in Germany, and five in China.

The metal-made Ultimate Seal™ is a uniquely designed and precisely engineered patented invention with no similar technology/product currently in the market. Its flexible radial tension automatically adjusts its shape and size continuously, significantly reduces friction against sealing surfaces. Simultaneously its multiple sealing layers can provide repetitious complete sealing effects, maintaining close to zero-leak sealing function. It can tolerate extreme temperatures from -220°C to 550°C, cope with both hydraulic and pneumatic ultra-high pressures up to 10,000 bar, and withstand concentrated acids or alkaline solutions.

This technology significantly improves performance in high pressure mechanical devices, reduces fuel consumptions, meanwhile substantially lowering the device’s manufacturing and operational costs. Ultimate Seal™ technology has the potential to change conventional industry practice, making machines stronger and more powerful.
