1. Factors which might have caused the variances in the difference between the quotes could be directly related to process, labor (people), and technology.

Bayfleet vs Fingold – There is a difference of process’ being utilized as the parts are stamped versus the older parts are made of numerous casting/machining of metal which typically took a longer lead time to produce. Quality could be an issue and certifications/specifications required for aerospace aircraft manufacturing may not be factored in. Because of the difference in technology and process’ used, the direct overhead to produce the products would be lower leading to lower costs in labour, overhead, and tooling. Fingold has also never dealt with large metal forming manufacturers before and are more experienced with machined products versus stamped. Bayfleet could also be trying to switch up their process from machining to stamping as the industry is moving away from machining which is more expensive and time consuming to produce which could be a possible reason for the lower price.
Bayfleet vs Union – There is also a difference of process’ being utilized here machining versus stamped products. Possible labour overhead cost maybe a factor in the prices and expertise in labour especially since each company specializes in different manufacturing technology. Quality could be an issue and certifications/specifications required for aerospace aircraft manufacturing may not be factored in. They also may already be doing similar jobs so setup may not be required making the costs lower. Bayfleet may also be coming in with a loss leader type of bid soliciting the business with a lower price only to increase prices after being awarded the business.
Taking a more in-depth look at the quotes:
Direct Labour Cost – rate at which labour is paid could be less due to involvement of engineering and more automated
