[0002] A hydraulic press is a machine that uses liquid pressure to transmit energy and is widely used in molding and processing in industrial production. They generate high pressure through a hydraulic system, applying powerful forces to the workpiece to achieve plastic deformation. Hydraulic presses not only excel in improving production efficiency but also enable high-precision and flexible processing.

[0003] A hydraulic press generally consists of three parts: the main machine, the power system, and the hydraulic control system. It is a machine that uses the static pressure of a liquid to process products made of metal, plastic, rubber, wood, powder, etc. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, deep drawing of thin plates, powder metallurgy, press fitting, etc.

[0004] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.
