During the course of completing the design for a heat-sensitive, thin-wall casting the engineer was mistakenly advised to thicken the walls of the part design from 3mm to 5mm to accommodate prototyping process limitations.
Thin wall prototype castings can present a challenge in the prototype world, but that does not mean that thin-wall parts cannot be cast and properly tested in prototyping processes. The engineer should not be asked to revise the design of the part in order to accommodate the limitations of a select prototyping process. Instead of changing the design to meet prototype process limitations, we recommend working with a proptotype supplier who produces more representative prototypes.
If you have concerns about the prototype castability of your thin-walled design, call us for a free consultation.
