High Tonnage Hydraulic Press Machine: Integrating PLC + Touchscreen + Grating Ruler for Smart Manufacturing

Since the introduction of hydraulic press machines, the technology has evolved drastically from simply applying force to being able to assist in automated tasks. By the year 2026, buyers are no longer interested in the basic statistics of a machine like its tonnage and cycle time. Instead, they are interested in data collection and real-time process control, as well as how a machine integrates into their smart factory. The answer is in the newest hydraulic press machines that utilize advanced mechanics and electronic controls.

GUANGDUAN‘s GY2S Series is designed with this in mind. The combination of a PLC based servo control, a user friendly touch screen, and a high precision grating ruler, this high toqnage hydraulic press machine is able to provide repeatability, traceability, and adaptability that modern manufacturing has to have, while also being powerful and safe.

The Increased Manufacturing Demands for Intelligent Hydraulic Presses in 2026

Due to the lack of process control in traditional hydraulic presses, the optimistic mindset of the operators was counterproductive. Manual control of stroke and pressure by the operators, combined with the lack of process change control, lead to the undetectable process variation which could only be detected in a quality control step that could be too late to salvage the part. This method is inefficient in high-mix, low-volume production which is typical in the automotive parts, home appliance components, and 5G Equipment Enclosure production.

The 2026 Smart Manufacturing report has found that 68% of the metal forming buyers are focusing their attention on real time process adjustability. Manufacturing smart hydraulic press machines is no longer competitive. The GY2S Series of press machines integrates the three most required functions from the metal forming technology buyers.

PLC + Servo Closed-Loop: Control that Improves Productivity

The core component of all GY2S Series machines is servo closed-loop control, which is a system that integrates a servo motor driver, PLC, pressure sensor, and displacement sensor. This innovation enables the system to make corrections to the output values every few milliseconds to enable closed-loop control, whereas open-loop control systems can only execute commands.

•Processes with no downtime can be adjusted on the fly: while the machine is in operation, operators can adjust the pressure, stroke, and speed from the touchscreen. This eliminates downtime from mechanical adjustments and recalibrations.

•The operational benefits of a servo motor: energy is conserved, noise is reduced operationally, and there is a minimal level of vibration. This is especially beneficial in a facility with multiple servo machines.

•Thanks to PLC’s storage of precise motion profiles, the quality of the processed stamped part and the operation’s repeatability remain unaffected by the level of skill of the operator or the time of day.

•High tonnage hydraulic presses that possess this level of control become instruments of precision manufacturing rather than being brute-force tools.

Touchscreen Control: 20 Mold Presets at Your Fingertips

Complex setups have traditionally been a major source of production loss. Each mold change could take 30 minutes or more of manual tuning. The GY2S Series eliminates this bottleneck through an intuitive PLC + servo system + touchscreen + grating ruler control architecture.

•Store up to 20 sets of custom parameters: Different products, materials, thicknesses, etc. customized optimized settings. The touch screen allows for instant recall, changeover time reduced from minutes to seconds.

•Digital adjustment on the fly for each mold and process: The operator has complete control to adjust parameter without stopping production. Make changes real time to correct modification of materials or resolve quality complaints.

•Touchscreen monitoring shows real time pressure, position, and cycle curve. This allows operators to be proactive and correct issues before causing rejections.

For a high tonnage hydraulic press machine operating in a Just-in-time scenario, total cycle time is reduced significantly and, as a result, it helps to immediately improve the OEE (Overall Equipment Effectiveness).

Grating Ruler Feedback: Closing the Loop on Position Accuracy

All hydraulic presses are prone to oil compressibility and seal deformation, leading to a loss of positional accuracy under high loads. The GY2S Series adds a grating ruler, a high-resolution linear encoder, providing real-time, direct feedback of slider position.

•Micron-level positioning regardless of the load: At full tonnage, the grating ruler senses the actual slider position and orders the PLC to compensate on the fly.

•No more Depth Drift: Mechanical wear, oil temperature changes, or temperature changes no longer affect depth accuracy because the closed loop always corrects to the target.

•Coining, embossing, and precision forming are all essential: Industries requiring tight thickness tolerances—like automotive gaskets or electronic shielding—benefit directly.

This high tonnage hydraulic press machine is equipped with a grating ruler, providing repeatability that rivals many of the servo mechanical presses, while offering the versatility and lower tooling cost of hydraulics.

Incorporation of Safety Features with Smart Controls

Advanced technology does not mean compromising the safety of the user. The GY2S Series has integrated multi-layer safety features that work in tandem with digital controls.

•Slider locking device: Locks the slider to any position and will not allow the slider to drop in the event of a tool fall. This mechanical backup will work independently from the control system.

•Lower limit switch protection and anti-repeat two-hand controls: This product safeguards against unintended cycling and ensures that the operator is keeping both hands out of the danger zone.

•Anti-error protection in touchscreen parameter settings: The system does not allow the user to input values outside the acceptable range of the specified tool and is not outside of the allowable limit that could exceed the damage of the tool or the press.

For all of the above reasons, the GY2S Series is a powerful and safe high tonnage hydraulic press machine and meets or exceeds the 2026 global safety regulations, including ISO 16092.

Thin-Oil Circulation: The System Designed with Reliability in Mind

•Smart controls cannot control a poor mechanical system. The GY2S Series is constructed with a high-quality steel welded box for the structure, providing strong rigidity and a clean, transportable design. The slider is designed with the same level of sturdy construction and is guided by an eight-sided full guide rail system to retain precision after millions of cycles.

•Thin-oil continuous circulation lubrication: This system ensures that all moving parts of the system are provided a friction-reducing, heat-reducing, and wear-reducing clean oil, extending the life of the press and operating components by years. Designed for 24/7 use, this system is crucial for any high tonnage hydraulic press machine.

•Low maintenance intervals: The continuous filtration and circulation mean less oil degradation and fewer lubrication-related stoppages.

The 2026 Buyer‘s Verdict

Smart manufacturing is not a future concept—it is today’s purchasing reality. A high tonnage hydraulic press machine equipped with PLC + touchscreen + grating ruler gives you:

•Faster changeovers (20 stored presets)
