A military ground assault vehicle manufacturer approached Spirol Industries to provide quick delivery of adjustable shim packs for spacing of armoured vehicle door hinges. The spacing is critical providing proper sealing and locking engagement of the door systems. Spirol worked with the customer to determine the required adjustment and developed three Edge Bonded Shim Set proposals. The customer selected the Spirol solution as it offered safe and quick adjustment, a 70% cost reduction and a short manufacturing lead-time.
Spirol’s Edge-Bonded Shim Sets have all the performance and cost advantages of solid and loose shims, but instead of having to stack a number of individual shims, a single shim set can be quickly adjusted to the desired thickness and slipped into position. In this way, variable close tolerances can be achieved, saving considerably on the time required to pick various different thicknesses of loose shims.
The Spirol solution has also provided cost savings by reducing assembly time and minimising related inventory storage space. It also provides cost saving advantages over surface-bonded shims because the materials are less expensive. Edge-Bonded Shim packs offer safe adjustment in seconds rather than using time consuming and difficult to peel surface bonded laminates. Safety improvement is realised because no knife is needed to remove the edge-bonded layers. Cost savings can also be realised because the removed layers are reusable functional parts.
