BACK PRESSURE FORMING: KEY FACTS The back pressure forming process was developed by Superform to form structural airframe components in 7475 alloys. Similar to Cavity forming, the process differs by using air pressure from both sides of the sheet, and slowly forming the hot sheet using slight pressure differential. This maintains the integrity of the sheet supressing cavitation and allows forming of "difficult" alloys. Maximum plan area of part (in general) 4.5 square meters. | ||
