Rectangular Aluminum Assembly Frame with Enclosure Assembly and Internal Mounting Bosses

Mounting boss height and through-hole position tolerance are the key callouts for an aluminium enclosure assembly with perimeter flange; boss height out of specification causes the installed sub-assembly to sit at the wrong axial position, while through-hole position error prevents the mating fastener pattern from engaging at the design shear load path. Shanghai Tangshan Electronics (Shanghai, Shanghai, established 2005) fabricates this aluminium enclosure assembly with rectangular frame, internal mounting bosses, and perimeter through-hole flange at their in excess of 20,000 m² Shanghai facility, with boss height, hole positions, and frame squareness verified to your drawing requirements during first article review. ISO 9001, ISO 14001, and ISO 45001 triple certification governs production traceability for aerospace, robotics, eVTOL, and contract manufacturing enclosure assembly applications.
