DDS RACK SYSTEM:

MMC’s DDS Rack System is the largest in the world, and it’s unique because the system is composed of an All-in-one-Process. Once parts are racked by a trained MMC Rack Operator they are washed, rinsed, dried, shot-blasted, base-coated, and top-coated if necessary. Once going through the All-in-one-Process, the parts exit the system as a finished product. Parts are then carefully taken off the rack and packaged to the customer’s specific requirements. The design of the DDS Rack System is the ultimate in soft-handling; parts are only touched twice (by hand) during the coating process. Thus, ensuring there is NO thread damage, thread fill, or part-on-part marring during processing. Due to its size and sophistication, the DDS Rack System is able to process bolts and U-Bolts in a variety of sizes. MMC processes parts from M6 to M36 in diameter and up to 750mm in length.

The DDS in “DDS Rack System” stands for Dip, Drain, and Spin. Unlike most other Rack Systems in North America, this system does not use a spray application for the coating process. Instead, parts are submerged in coating and slowly rotated which gives MMC the ability to process parts with complicated geometrics.

The act of rotating while parts are submerged ensures that regardless of the intricate design of a part, the entirety of the surface area is covered with coating. Parts are then removed from the coating and spun at high speed to achieve optimal coating thickness and weight on each and every part.
