Product Overview
Welding Operations: Employs Yaskawa and Panasonic robotic welding systems to join formed sheet metal panels. The automated process produces consistent seams that define the structural framework of the enclosure.
Mechanical Assembly: Integrates functional hardware into the fabricated metal shell. This process involves the installation of doors, hinges, standard or custom locking mechanisms, and internal mounting plates as specified in client drawings.
Sealing and Finishing: Prepares the enclosure for specific operating environments. This stage includes applying sealing gaskets for ingress protection and utilizing an automated powder coating line for surface coverage.
Consolidated Manufacturing: Executes laser cutting, CNC bending, welding, painting, and hardware assembly within a single facility. This single-source approach coordinates the entire production cycle from flat sheet metal to the final assembled cabinet.
