Express Pattern (Buffalo Grove, IL, 847-215-0001), a leader in producing high
quality stereolithography models, and QuickCast and ThermoJet investment casting
patterns, was asked by Hitchiner Manufacturing (Milford, NH) to assist with a
challenging project. Hitchiner had proposed a significant redesign of an existing
component to a potential customer. The part under consideration was a complex
weldment of sheet metal and machined components. Hitchiner proposed that the component
instead be investment cast in two pieces and laser welded together. Express
Pattern split the provided UG solid model and built a sample part of one component.
Hitchiner used the ThermoJet component to demonstrate to the customer that necessary
detail can be achieved with the ThermoJet wax printer. The sample pattern was
used by Hitchiner as part of their presentation to their customer, who was so
impressed, they agreed to go with this new approach. Express Pattern is currently
building prototype wax pattern injection dies to satisfy the higher quantity initial
customer trials at Hitchiner. |
