Functional Characteristics and Applications of Folding Machines

Folding machines are mechanical devices used to bend materials such as metal sheets and plates. By applying external force, they plastically deform the material to a predetermined angle and shape. They are widely used in the manufacturing industry for sheet metal forming. They can bend flat materials (such as metal and plastic sheets) into specific angles or shapes (such as V, U, and Z). Their processing accuracy directly impacts the product's assembly quality and appearance. Through the coordination of molds (upper and lower dies), they utilize mechanical, hydraulic, or pneumatic forces to bend the material at the applied force points, ultimately achieving the desired bending effect.

Compared to press brakes, folding machines focus more on edge processing of thin sheets (typically ≤2 mm), such as folding, curling, and pressing, prioritizing edge smoothness over complex angles. Folding machines are compact and typically utilize single- or double-sided folding mechanisms. Some models feature roller-assisted shaping, making them suitable for continuous edge processing. Hemming machines are commonly used in detailed processes such as trimming sheet metal edges, flanging kitchenware, and hemming door and window frames. They are often used in conjunction with press brakes, with the press brake performing the main bending and the hemming machine handling the edge details.

Flanging machines, with their ability to precisely process thin sheet metal edges, are widely used in detailed processes across multiple industries. In sheet metal processing, they are used to hem the edges of enclosures such as distribution boxes and control cabinets, ensuring a tight seal and smoothness during assembly. In kitchenware manufacturing, they are used to curl the edges of stainless steel sinks and stovetops to eliminate burrs and enhance the feel. In the door and window building materials industry, they are used to hem the frames of aluminum alloy and plastic-steel doors and windows, enhancing structural stability and aesthetics. In home appliance manufacturing, they are often used to press the edges of metal inner containers of air conditioners and refrigerators to prevent scratches during assembly. Furthermore, they play a key role in edge trimming and hemming in the processing of stainless steel housings for medical devices, metal covers for lamps, and automotive interior trims, ensuring product precision and safety.
