Suitable for stamping, bending and forming work.
It can run continuously with stable performance and long service life for workshops.

PRODUCT INTRODUCTION 

Overview

This press is built with a thick, welded steel frame that offers greater strength and durability than conventional cast iron designs. The open‑back C‑frame construction provides excellent access for die mounting and is well‑suited for processing larger workpieces. Engineered for continuous stamping, bending, and forming operations, it delivers stable performance and reliable service over long production runs, making it a practical choice for demanding workshop environments.


Features

Welded steel structure ensures high rigidity and impact resistance, maintaining accurate alignment under heavy loads.

Open‑back design allows unrestricted access to the die area, simplifying tool changes and reducing setup time.

Suitable for a variety of operations including blanking, piercing, bending, and shallow forming.

Built for continuous operation with low vibration and consistent cycle‑to‑cycle repeatability.

Simplified mechanical system minimizes maintenance needs and extends service life.

Compact construction saves floor space while providing robust stamping capacity for daily workshop use.
