Vacuum Products
The MDC product line has evolved against a backdrop of careful research and development as well as the implementation of the latest in automated manufacturing techniques. Multiple axis Mazak® CNC machining centers are at the heart of all metal machining operations at the Hayward, California facility. These sophisticated, robotically controlled machines are designed for continuous operation producing finished components from raw stainless steel. Engineering and design are routinely implemented using 3D Modeling/Solid-Works and Finite Element Analysis (FEA) computer work stations networked with one central system which is accessible to all production facilities. The main manufacturing facilities, located in Hayward, California, contains 107,000 square feet of manufacturing space.
