To treat every customer like they are the only customer!
We get things right the first time!
Along with receiving a high-quality product in a short lead time, most companies want their product produced at the lowest possible cost. One of our guiding principles here at PFI Precision is to provide our customers with the most cost-effective solution for producing close-tolerance component parts and mechanical assemblies. In our everyday operations we continuously look for ways to reduce manufacturing expenses and simplify assembly.
With our deep understanding of the principles of industrial design and advanced technical competencies, one of the things we focus on is identifying more strategic methods for manufacturing existing products. While we were in production of the precision hinge component highlighted here, we initiated a cost savings idea to the customer.
Constructed from 303 stainless steel for use in the food service industry, this hinge component featured overall dimensions of 2.5” in length x 4” in width and had a sand blasted matte finish. The original design incorporated a welded-in cross pin, as shown in the hinge on the left. We immediately explored the possibility of press-fitting the pin as an alternative solution. With machining tolerances specified at ±0.0005”, they were well within the specifications needed to make an interference fit. Our engineers proposed a series of very well thought-out design modifications to ensure a precise fit and maximum joint strength. After putting our ideas to the test and calculating the cost implications, we approached the client with our idea.
The net result of producing the part under our alternative scenario was a cost savings of $2.00 per unit. The client’s in-house technical team assessed our value-engineered solution and accepted our proposal. Now, after turning and milling the hinge body, we use an arbor press to assemble the final workpiece right at the machining station.
By eliminating the weld in the original specification, our re-design resulted in a part that was easier to assemble and could be produced faster and at a lower cost. For the 2,200 units in the initial order, the cost savings was $4,400. We now collaborate with the client’s engineers on a regular basis on design-for-manufacturability solutions.
