Brand History
YEH CHIUN’s origins date back to 1984, when it began producing hydraulic press brakes, laying the foundation for its expertise in precision machinery. In 1987, the company developed NC hydraulic press brakes, which entered production the following year. By 1989, YEH CHIUN relocated to its current site in Wuri, Taichung, and started developing CNC three-axis hydraulic press brakes, achieving mass production in 1990. In 1992, the company advanced to CNC four-axis hydraulic press brakes, with production commencing in 1993. By 1994, YEH CHIUN expanded into NC hydraulic shearing machines and collaborated with Yuan Chang to develop NC and CNC cold-rolled plate forming machines. That same year, the company began developing CNC five- to eleven-axis high-precision hydraulic press brakes, launching them in 1996. In 2005, YEH CHIUN introduced automated hydraulic shearing machine feeding and collecting production lines, marking its shift toward automated integrated systems.
In terms of quality certifications, YEH CHIUN achieved CE certification in 1998, ISO-9002 in 1999, and upgraded to ISO-9001 in 2002. The company also secured EMC electromagnetic compatibility certification, CE certification for C-type presses, and Dun & Bradstreet business certification. These certifications reflect YEH CHIUN’s commitment to safety, quality, and environmental standards. The company continues to invest in research and development, expanding its product range to include automated electromechanical systems, OA office furniture forming equipment, refrigeration panel forming equipment, cleanroom partition wall forming equipment, and cold-rolled steel structure automation systems. YEH CHIUN’s strategy emphasizes standardized and modular components to ensure interchangeability and enhance maintenance efficiency, maintaining a competitive edge.

The YCS-HD model, a CNC multi-axis direct-cut hydraulic shearing machine, offers high-precision control for complex cutting tasks.
- YCS-HA NC Direct-Cut Hydraulic Shearing Machine: Features backgauge precision with a motor speed of 1420 RPM, a reduction ratio of 10:1, and accuracy within ±0.1 mm. The backgauge stroke is 800 mm, with a cutting length range from 0.1 m to 9.9 m and a counting capacity of up to 9999. It includes electric rake angle adjustment, electric blade gap adjustment, and a hydraulic cylinder return system to absorb cutting vibrations, enhancing operational stability.
- YCS-HM NC Direct-Cut Hydraulic Shearing Machine: Employs synchronized hydraulic cylinders and a direct-fixed upper blade slide for vertical cutting, ensuring a smooth and precise cut surface. It automatically adjusts clamping cylinder pressure based on load, suitable for cutting sheets from 0.1 mm to 25 mm thick. The machine uses a logical circuit controlled by sequence valves, operating without vibration, with low noise, and stable oil temperature and pressure. The body is constructed from welded steel plates, annealed to eliminate internal stress. Safety features include overload protection and a safety guard. Blade gap adjustments can be manual or computer-controlled, with a precision ball screw-driven backgauge maintaining ±0.1 mm accuracy. Optional features include a material retraction function and an automatic rear material support system.
- YCS-SM NC Swing-Beam Hydraulic Shearing Machine: Designed for smaller-scale or specific-angle cutting needs.
Standard accessories include side gauges, front supports, a ball transfer table, a light projection line device, and anti-scratch clamping cylinders. YEH CHIUN’s shearing machines prioritize durability and efficiency, offering standard and optional accessories to meet diverse user requirements.
Press Brake Product Overview
