Case Study: Electric Door Parts Created through Investment Casting

Electric Door Parts Created through Investment Casting


The customer initially manufactured the electric door part using bar stock, involving intricate Gang milling process  resulting in escalated production costs as well as down town to load and unload fixtures. 

The tolerance of the slot were very tight. We had a  zoom meeting with customer and our focus was to explore if the tolerance of the slots can be 0.004 inches . Customer was not open to do so due the  mating parts was also a close tolerance cylinder.


 Our enginerring team visited customer to understand how the complete mechanism operated. Finally we made the subject parts as well the mating cylinder via investment casting so the tolerance stack was functioning better then parts made machining methods.


The shift to Investment Casting realized a notable 30% cost savings. The intricate slots required for the electric door part were efficiently produced, significantly enhancing the overall efficiency of the manufacturing process.
