I. Project Overview
This delivery includes two models totaling over twenty units, both high-end servo energy-saving horizontal single-action extrusion presses. They feature short-stroke, rear-loading billet design, with the entire machine structure optimized through 3D finite element simulation. Core components use high-quality forged and cast steel from renowned mills, while hydraulic and electrical systems use top-tier international brand components. The presses process 1-8 series aluminum and aluminum alloys, with stepless speed adjustment from 0.2 to 20 mm/s. Equipped with intelligent control systems, dual die quick-change mechanisms, and integrated shearing devices, they combine high rigidity, high precision, high productivity, and low energy consumption. The two complementary tonnage models are suited for medium and large-scale aluminum profile production, fully meeting the continuous, high-quality, cost-effective production needs of large aluminum groups.
II. Core Equipment Advantages
1. Heavy-duty pre-stressed frame with premium materials for long-term high precision
The entire machine uses a closed pre-stressed composite frame, optimized through stress field, displacement field, and temperature field 3D finite element simulation.
Front beam, cylinder base, and moving beam use ZG270-500 cast steel; main cylinders are 35# integral forged steel; tension columns use 42CrMo quenched and tempered forged steel;
Main plunger surface is hardfaced with 3Cr13 stainless steel for high hardness; container liner uses H13 heat-resistant steel, outer sleeve uses 5CrMnMo alloy steel for heat resistance, wear resistance, and long service life;
All cylinders and piston rods use high-quality composite seals with copper sleeve guides for excellent sealing performance, eliminating high-pressure leakage.
2. Servo energy-saving system for significantly reduced production costs
Both models feature liquid-cooled servo drive systems with dedicated closed-loop cooling:
Servo motors operate at up to 95% efficiency, with near-zero no-load current and start/stop response as fast as 0.3 seconds, reducing impact and losses compared to conventional motors;
Dynamic speed and displacement adjustment based on production conditions enables "on-demand power supply", with total energy savings of 15%~30%, especially notable when processing hard aluminum alloys;
Proprietary liquid cooling maintains motor and driver temperatures below 40°C/35°C respectively, with no scale or oil buildup, solving the cooling challenge for high-power servo systems and extending motor service life.
3. Top-tier hydraulic and electrical components for stable, reliable operation
Hydraulic system delivers smooth pressure output with low noise and low failure rate;
Electrical system uses international brand components as standard, supports integration with plant systems for strong intelligent management;
Equipped with multiple pressure, temperature, position monitoring and safety interlocks, with full emergency stop and overpressure alarm functions for high production safety.
4. Automated design for maximum production efficiency
Short-stroke + rear-loading layout: compact action cycle, short non-extrusion time, higher output per unit;
Dual die holder quick change: alternating die holders eliminate long downtime for die changes, offering strong flexible production capability;
Main shear integrates residual knocking + automatic blade opening to prevent material sticking and die scratching, ensuring clean cuts;
Servo-driven billet loader with precise positioning and flexible movement, can be quickly disengaged when billet jams occur for easy maintenance.
High parts commonality across models reduces whole-line maintenance costs, ideal for centralized layouts in large industrial parks.
III. Applicable Products
2000T: window/door profiles, curtain walls, PV brackets, small-to-medium industrial profiles, tubes and bars;
2700T: new energy vehicle parts, rail transit profiles, large-section wide profiles, engineering machinery, high-end building structural components.
