Mechanical Design

Kalsi Engineering has a proven track record in developing new designs and products from concept to full production. Our mechanical design team is supported by our comprehensive analysis and testing capabilities. Our engineers and designers have extensive experience in machining, welding, tooling, and other manufacturing processes used in the fabrication of a broad range of mechanical and structural equipment. We utilize state-of-the-art, computer-aided design software tools to support our design and development activities.

Our accomplishments are reflected by numerous improvements and patents related to valves, static and dynamic seals for demanding applications, downhole drilling tools, bearings, measurement-while-drilling equipment components, wellhead equipment, and unique thread geometries. We have formed world-class alliances to market our technology, and several of our patented products are licensed to multi-national companies for manufacturing and worldwide marketing.
