Blechteilen

Blechteilen, or sheet-metal parts, are components manufactured from sheet metal that are shaped, cut, bent, or joined to form functional parts used across many industries. They are typically produced from metal sheets with thicknesses ranging from about 0.5 to 25 millimeters, using materials such as steel, aluminum, stainless steel, copper, or brass. Common examples include enclosures, brackets, housings, vents, and stamped connectors.

Manufacturing of Blechteile involves several processes. Cutting methods include shearing, laser cutting, waterjet cutting, and punching to achieve the desired outline and holes. Forming operations such as bending, stamping, deep drawing, and hydroforming create the three-dimensional shape. Finishing steps like deburring, galvanizing, powder coating, or painting improve surface quality and corrosion resistance. Tolerances and springback are important design considerations; allowances are made to compensate for material behavior during forming.

Design and engineering considerations. Sheet-metal parts are typically designed for manufacturability, with attention to bend radii, hole sizes, and flange dimensions to avoid tearing or excessive springback. Fastening and joining strategies—welding, riveting, screwing, or adhesive bonding—are chosen based on load, weight, and assembly requirements. Standard components such as nuts, screws, and hinges are often integrated using progressive stamping or modular fabrication.

Applications and trends. Blechteile are ubiquitous in automotive, electronics, appliance, HVAC, and construction industries. The use of CAD/CAM, laser-cutting and CNC-bending, along with lightweight materials and sustainable coatings, continues to shape modern sheet-metal part production.
