Edelbrock Aluminum Foundry and Machining Full Tour & Behind the Scenes! (Pouring Molten Metal!)
What happens here
After cooling, the cast parts, still encased in sand, are transported to a large heat treatment oven. The parts are heated again to soften the sand cores, making them easier to shake out. Following the oven, the parts move to a vibration station where a large vibrator removes the sand from the internal cavities, leaving only the raw aluminum casting. Any excess metal from the runners and risers is also broken off.
Goal: Remove sand cores and initial excess metal from the castings.
