Three Process Families, One Manufacturer — Whether you need precision hot forging of alloy steel, closed-die stamping, or versatile open-type pressing — Portower's catalog covers the full range of industrial forging and stamping processes.
The VFP Series is Portower's flagship hot die forging press, engineered for high-energy, high-frequency precision forming of steel, alloy, aluminum, and copper forgings. Built on a four-column prestressed frame with an integrated eccentric gear drive, VFP presses deliver stable striking energy and exceptional angular stiffness — critical for consistent flash-line and dimensional accuracy in high-volume forging production.
Equipped with automatic centralized lubrication, hydraulic overload protection, and a PLC-based control system with touchscreen HMI, VFP presses are ready for integration into full forging automation cells — including induction heating, robotic transfer, and trimming press lines.

The VFP-G Series is the G-type (wide-body) variant of Portower's hot die forging press platform. Sharing the same four-column prestressed frame and eccentric gear drive technology as the VFP, the VFP-G features an enlarged bolster area and extended die height clearance — making it ideal for large-envelope, multi-impression die sets used in complex forging operations.
The increased working space allows for simultaneous pre-forging, finish-forging, and flash-trimming operations within a single die set, reducing the number of handling steps and improving production efficiency. Like all VFP-family machines, VFP-G includes hydraulic overload protection and full PLC automation capability.

The VCP Series is Portower's open single-point (C-frame) mechanical press — engineered for versatility and ease of use in general stamping, bending, forming, and light drawing applications. The open C-frame design provides three-sided die access, making die changes fast and straightforward, and enabling easy integration with coil feeders, conveyors, and part-transfer systems.
Despite its accessible open frame, VCP incorporates a precision-ground four-face slide guide and a robust crankshaft drive to maintain consistent slide parallelism and stroke accuracy. Pneumatic clutch/brake assembly, PLC control, and standard safety features make VCP ready for both manual operation and automated line integration.
