A fuel injection systems manufacturer had incorporated the use of two steel brackets to clamp the fuel rail to the top of the engine. The customer was looking at changing these brackets to plastic as a cost reduction. In order to prevent deformation of the plastic bracket during the tightening of the bolt, a Compression Limiter was required.
The customer originally investigated the use of a machined Compression Limiter, but the savings from changing the metal bracket to plastic would have been lost considering the high price of the machined Limiter. The customer approached SPIROL to help provide a lower cost solution for the Compression Limiter.
SPIROL Engineering recommended the use of a standard CL200 (non heat treated) Compression Limiter based on the rated proof load of the bolt that was used in the assembly. This roll-formed Compression Limiters is a fraction of the cost of a machined Compression Limiter. In addition, the flexibility of the roll formed Limiter enabled the customer to widen their hole tolerances which further reduced the cost of the assembly as the machined Limiter would required significantly tighter tolerances.
SPIROL's objective is to recommend the lowest installed cost component. Due to the fact that SPIROL has a vast standard range of products, often times samples are provided from stock at minimal cost.
