Vacuum Formed Ventilation Grill Assembly for Mass Transit Application

Vacuum Formed Ventilation GrillA customer in the transportation industry approached Golden Plastics Corp. to manufacture a heavy duty ventilation grill assembly for a mass transit application. The two part assembly was constructed of Boltaron 4800, a fire retardant acrylic/PVC alloy sheet designed specifically for mass transit and aircraft interiors.

Each section was formed on our 3-staion rotary vacuum forming machine, and CNC routed to finished dimensions. Both grill sections and the stainless steel brackets would be assembled using a structural acrylic adhesive and ultra sonic spot welding. The finished part measured 24" in length, 48" in width, 1" in height, and be 0.125" thick, and feature a light textured finish. The combination of materials and process allowed this product to easily meet a number of stringent regulations that are imposed on mass transit related materials.
