Professional Sheet Metal Forming Automotive Industry

BENDING: CREATING ANGLES, CURVES, AND COMPLEX GEOMETRIES

Bending is a common sheet metal forming process that shapes the metal sheet along a straight axis to create angles, curves, and complex geometries. This process is widely used in manufacturing brackets, enclosures, frames, and other structural components. Bending can be performed using press brakes, which use punches and dies to shape the metal sheet.

Bending offers several advantages, including high design flexibility, cost-effectiveness, and the ability to create strong and durable parts. The process allows for the formation of both simple and complex shapes, making it suitable for a wide range of applications. For example, bending is commonly used in the production of automotive body panels, HVAC ductwork, and furniture components.

DEEP DRAWING: CREATING HOLLOW-SHAPED COMPONENTS

Deep drawing is a sheet metal forming process used to create hollow-shaped components like cups, cans, and containers. The process involves pulling a metal sheet into a die cavity using a punch. As the punch forces the metal into the die, it undergoes plastic deformation, resulting in the desired shape.

Deep drawing offers excellent material utilization, minimizing waste by taking advantage of the sheet’s inherent ductility. It provides high dimensional accuracy and surface finish, making it suitable for applications requiring tight tolerances. Deep drawing is commonly used in the production of kitchenware, automotive parts, and metal packaging.

STRETCHING: CREATING COMPLEX CONTOURS AND CURVES

Stretching, also known as stretch forming, is a sheet metal forming process that involves elongating the metal sheet to create complex contours and curves. The process is commonly used in the aerospace industry to manufacture aircraft skins, fuselage sections, and wing components.

Stretching offers the advantage of producing smooth and wrinkle-free surfaces as the metal sheet is uniformly stretched over a die. This process allows for the creation of large and intricate parts without the need for multiple welds or joints. Stretch forming is widely used in industries such as aerospace, marine, and architectural metalwork.

ROLL FORMING: CREATING LONG, UNIFORM SECTIONS

Roll forming is a continuous sheet metal forming process that involves passing a metal strip through consecutive sets of rollers to gradually shape it into the desired profile. This process is commonly used to produce long, uniform sections with consistent cross-sections, such as metal roofing, cladding, and steel studs.

Roll forming offers high production rates and excellent repeatability, making it suitable for large-scale manufacturing. It allows for the creation of complex profiles with consistent dimensions and tolerances. Roll-formed components find applications in the construction, automotive, and appliance industries.
