I. Overall Equipment Introduction
This project includes 1650T and 2750T medium-to-large tonnage servo energy-saving extrusion presses. Both feature short-stroke, moving stem, rear-loading billet design, equipped with full servo drive systems and top-tier hydraulic and electrical components. Built specifically for precision aluminum profile production, they balance energy savings, efficiency, high precision, and stability, processing all aluminum alloy series. Manufactured to high industry standards, they are ideal workhorses for medium-to-large aluminum profile plants.
II. Core Equipment Advantages
(1) Rugged construction for long-term precision
1. Pre-stressed frame design – Heavy-duty pre-stressed structure with pre-tension 1.2x higher than tie-rod design force. Main cylinder, front beam, and moving beam use 35#/cast steel, with 40Cr quenched tie-rods for exceptional rigidity. Main plunger uses chilled alloy cast iron with high surface hardness for wear and impact resistance, maintaining tight tolerances under heavy loads.
2. Premium materials and workmanship – Container liner uses H13 heat-resistant alloy steel, outer sleeve uses 5CrMnMo steel. Extrusion stem, head, and other wear parts use high-grade tool steel for heat and wear resistance. All cylinders use premium seals with copper sleeve guides for excellent sealing and leak prevention.
(2) Servo energy-saving system for significant cost reduction
Both models feature liquid-cooled servo main control + servo manipulator system as key highlights:
1. Servo motors achieve up to 95% efficiency, far above conventional induction motors, with near-zero no-load current, fast response, and minimal grid impact;
2. Dynamic speed and displacement adjustment enables on-demand power output, with total energy savings of 10%~20%, up to 25% when processing hard alloy profiles;
3. Dedicated closed-loop liquid cooling maintains servo motor temperature below 40°C, preventing overheating, demagnetization, and scale buildup, significantly extending motor life.
(3) Top-tier components for reliable, easy maintenance
1. Hydraulic system – smooth high-pressure output, low noise, low failure rate;
2. Electrical system – mature brand components, precise signal transmission, simple HMI;
3. Cooling system – independent professional oil cooler for precise temperature control, ensuring long-term hydraulic stability.
(4) High automation for excellent productivity
1. Classic short-stroke + rear-loading design with servo-driven billet loader for precise positioning; fast cycle speed, short non-extrusion time, high efficiency;
2. Cassette-style quick die change and integrated residual knocking device with ample shear force for clean separation, reducing downtime for die changes, cleaning, and maintenance;
3. Supports manual, single-cycle, and full-auto modes with stepless speed adjustment to suit different processes and materials.
(5) Smart monitoring + full safety protection
Equipped with multiple cameras for real-time billet feeding and output monitoring; features overpressure, overtemperature, position interlock, and emergency stop with alarm functions. Supports remote data viewing and fault diagnosis for strong intelligent management.
(6) Extended warranty + full-service support
1. Long warranty period with strong after-sales support;
2. Includes full mechanical drawings, hydraulic diagrams, electrical schematics, wear parts list, operation manuals, and sufficient spare parts. Our technicians handle on-site installation, commissioning, and training for a worry-free experience.
III. Product Range
