San Precision Alloys Pvt. Ltd. Scores Marine Award with Casting Conversion
Plagued dimensional variation and poor aesthetics, the customer approached San Precision Alloys to address alternative methods of manufacture to produce marine deck mounts to secure the black box to the monkey deck of oil tankers, cruise ships and other large sea-going vessels. The ASTM A351CF8M 260 mm x 116 mm (10.236 in.
x 4.567 in.) deck mounts were originally fabricated as a weldment of outsourced flanges and pipes, which required machining, welding and inspection.
casting, the resulting product offered improved dimensional accuracy, aesthetic quality and surface finish while reducing manufacturing cost and lead time.
The resulting product
offered poor aesthetic and dimensional quality, requiring a high inventory of outsourced direct materials. By manufacturing this component as an investment

a supply gap. There was a shortfall in the supply of Control Housings for Military Aircraft.
The customer came to Barron with an urgent need to fill Deliveries of the component,
which measures 12 in. x 10 in. x 4 in. and is produced in 17-4 PH stainless steel, was falling behind customer requirements. The component design has a high degree of complexity
with tight as-cast profile tolerances on a part that wants to distort during casting cooling and is challenging to straighten. This was found to be the key reason that deliveries were not being met.
Barron utilized 3D printed patterns and rapid manufacturing techniques to provide fully processed First Article parts in eight weeks and then launched into monthly production deliveries. Barron was able to not only meet the program’s urgent demand requirements but they also put the program back on schedule. Improved product reliability came from producing the
components from SLA Quickcast 3D printed patterns, with no hard tooling required. The SLA Patterns are more stable than wax patterns in maintaining dimensions and configuration, thus reducing the degree to which the previous parts were distorting, which affected component supply.
Using printed patters also had the benefit of saving the customer a significant ®

non-recurring expense by eliminating the need for tooling as well as taking tooling lead time out of the planning equation.
