It is widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. It applies strong pressure to metal blanks, causing them to plastically deform and fracture, thus forming parts. Also known as a hydraulic press or oil press, a press consists of four components: a four-column, top-loading hydraulic press; a modular control cabinet; an electric heating system and insulation device; and a mold conveyor frame. These components utilize an integrated design, resulting in a sleek and aesthetically pleasing design, compact structure, simple and reliable operation, and easy maintenance.
