Bridging Investment Casting Technology to the Future
CAST YOUR VOTE!
T
his year, we are trying something new that involves every attendee.
the winners of this year’s casting contest, we are making
you the judge. Every participant using the Whova App can vote for the best casting in a number of categories from our finalists, as well as voting for the best overall casting. You each get one vote per category, so use them wisely. Honors in seven categories
will be awarded at the
Investment Casting Institute’s Annual Casting Contest at the 70th Annual Technical Conference and Exhibition in Pittsburgh, PA. Awards will be presented for the following categories: Automotive, Defense, Fine Art, General Industry, Marine, Medical, and a new overall category, Best In Cast
ENTRY: CASTING 101 Approached by their customer to manufacture a
revolutionary marine propeller, the foundry worked with their customer to develop a process that would yield an acceptable part using Additive Manufacturing.
The investment casting
process was selected due to the shape of the blades and the ability to achieve near net shape, reducing machining cost. Due to this complex geometry of the part, it was determined that 3D printed patterns would be far easier and more cost effective than constructing traditional tooling. A major challenge in producing this component is the requirement to provide it in a fully machined and polished state, thus the casting must be free of shrink and porosity to produce a conforming propeller. The foundry designed a gating and pouring system that is robust enough to pour as both a PMMA and an SLA Quick Cast pattern in relatively high volumes with industry leading low foundry scrap. The design prevents the blades from moving during solidification which reduces set up time at machining. Their customer has saved significant processing time and reduced scrap though concurrent engineering.
12 ❘ August 2023 ® award. Instead of a panel of judges choosing Please note that the categories of Defense and Medical
have only one finalist each, so they are winners by default and there will be no poll taken for those categories. These castings are eligible for the Best in Cast recognition and will appear in that poll. The casting contest is open to members of the Investment Casting Institute and was designed to recognize foundries which manufacture parts and components that best illustrate and promote the benefits and flexibility of the investment casting process, or which demonstrate problem solving techniques for the customer.
