What is Metal Bending?
Metal bending is a fabrication process that shapes metal by applying mechanical force to achieve a specific angle or form. This method is crucial for manufacturing components with precise angles and curves, making it essential for creating durable and functional parts in various industries.
At Lewei Precision, our sheet metal bending services cater to a wide range of client needs, from simple to complex designs. Equipped with advanced electric and hydraulic press brakes, we ensure precise bending even for parts with tight tolerances. Our user-friendly platform allows you to instantly receive quotes by uploading your 3D CAD files, streamlining the transition from design to production. In addition to bending, we offer comprehensive post-processing options, ensuring that the parts are ready for immediate use in prototypes or final products.
How does Metal Bending Work？
Metal bending is a crucial method in metal fabrication that involves deforming metal into a desired shape by applying force, typically using a press brake or similar machine. This process allows for precise forming along a straight line to create shapes such as V, U, or channel bends in sheet metal. The technique can range from manual methods to advanced CNC (Computer Numerical Control) systems, which offer enhanced precision and repeatability.
This metal bending technique is widely used for producing strong, functional parts efficiently. It is commonly employed to create components ranging from small brackets to large architectural features. With the evolution of CNC technology, complex and highly precise bending tasks are now more feasible, offering greater design flexibility and faster production cycles. CNC systems are especially beneficial for mass production, providing minimal variation and ensuring consistent quality across large batches.

Metal Bending Workshop
Metal bending transforms flat sheets into 3D shapes by applying precision force, using advanced machinery to create bends at designated angles. Prior to bending, flat sheets are prepared through cutting methods like laser cutting, ensuring high accuracy. We utilize high-tonnage equipment, capable of applying up to 1000 tons of force, and can handle materials with lengths up to 7200mm. Each bend is executed using a precise mold with a range from R3 to R50, guaranteeing accuracy with a machining tolerance of ± 0.1mm.
This process is ideal for various applications, including machinery components, architectural features, and custom designs. Our custom metal bending services offer tailored solutions with high precision and consistency.
