EDIT: Can't seem to edit the title which should read "What Pressure Is Required For Pressure Casting And What Vacuum Is Needed To Degas Resins and Rubber?
I am wanting to buy a Vacuum Pump that can be used to degas as well as also be used (via a tank) to really make my Vac Form Table perform.
Right now I am using a vacuum cleaner for the Vac Form Table and whist it works on small items, it does not provide enough suction for larger jobs. As I understand this, I need a tank that can be de-pressurized by a Vacuum Pump. The pump is shut off once full vacuum is achieved and the suction to the table is controlled by a ball valve. If that makes sense.
Q: How large would the tank need to be?
I am thinking that this tank could also be used as a Vacuum Chamber.
Q2: Can I do this or am I best to have a separate chamber?
I also would like to get a pressure chamber for casting. And specs for this as well would be very much appreciated.
Q3: What pressure is actually needed for casting?
