A military ground assault vehicle manufacturer approached Spirol Industries to provide quick delivery of adjustable shim packs for the spacing of armoured vehicle door hinges.  This 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 0.05 mm 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.

Spirol’s Application Engineers worked with the manufacturer to determine the required adjustment and developed three Edge-Bonded Shim Set proposals.  The advantages were evaluated and a proposal offering safe, quick adjustment, a 70% cost reduction and a short manufacturing lead-time was selected. The solution was provided without tooling cost using Spirol’s tool-less manufacturing technology.

Spirol offers offers free samples and application engineering support.  The company’s Application Engineers will review a customer’s application needs and work with their design team to recommend the best solution.
