Aluminium Chassis with Open-Frame Electronics Chassis and Internal Horizontal Guide Rails

When the internal horizontal guide rails inside an open-frame electronics chassis are not at the same height and parallel to each other, inserted PCB card guides bind on entry and the boards do not seat in their connectors; guide rail height consistency and rail-to-rail parallelism are the callouts that determine whether the chassis accepts card inserts without force. Shanghai Tangshan Electronics (Shanghai, Shanghai, established 2005) fabricates this aluminium open-frame electronics chassis with internal horizontal guide rails at their close to 20,000 m² Shanghai facility, with guide rail height, rail parallelism, and slot pitch confirmed to match your drawing at first-off inspection. ISO 9001, ISO 14001, and ISO 45001 triple certification covers aerospace, consumer electronics, semiconductor, and contract manufacturing chassis applications.
