Guangduan GRT – Precision High-Speed Press

🏗️ Oil-Locked Tie-Rod Frame · ⚖️ Standard Dynamic Balancing · 🧠 Optimal FEA Design

The GRT is a high-speed press series built for the most demanding precision applications. Its high-strength cast iron body is optimally designed using Finite Element Analysis (FEA) for maximum durability and rigidity. A key distinction of the GRT is its body structure, connected by tie-rods and powerfully locked 24/7 by high-pressure oil, ensuring the machine's rigidity is maintained long-term. The press comes standard with a reverse dynamic balancing device that completely suppresses vibration and noise, providing optimal stability and precision while extending die life.
