Armored Vehicle Door Hinges
A military ground assault vehicle manufacturer approached SPIROL to provide quick delivery of adjustable Shim packs for spacing of armored vehicle door hinges. The spacing is critical to the welding process, providing proper sealing and locking engagement of the door systems.
The customer designed an adjustable Shim pack based on surface bonded Shim material requiring 94 layers of 0.002” thick laminates. Because of the size and configuration of the parts, surface bonded materials were problematic in cost, the amount of time needed for dimensional adjustment, as well as a long lead-time required for manufacturing.
