Bulge forming is becoming increasingly popular among manufacturers because of its ability to produce seamless, lightweight, “near-net-shape” parts. From aerospace and automotive to oil and gas, bulge forming allows manufacturers to quickly and accurately form complex shapes.
During the bulge forming process, operators insert a blank into a mold and introduce pressure (typically via water or air) into the chamber. The pressurized media forms the material to the shape and contour of the tool. Throughout this process the press acts as a clamp, applying force to the tool in order to counter the pressure being injected into the chamber, ensuring the tool remains closed. Fluid (hydro) bulge forming is typically used to forming cylindrical shapes such as tubes or canisters whereas pneumatic (air or gas) bulge forming is most often used to form spherical shapes such as discs or tank heads.
Beckwood’s bulge forming presses are ideal for manufacturing parts from a variety of materials including aluminum, steel, and other high-strength alloys. Using a Beckwood Bulge forming press, you can produce everything from a simple dome or tank head to complex shapes with non-symmetrical features while maintaining uniform wall thicknesses.
