Straight-side double crank press
Product Description
LFE Series Three-Point Straight Side Press Machines (400–1200 Ton)
The LFE Series is a heavy-duty three-point mechanical press engineered for large-format and high-precision metal forming. With press capacities ranging from 400 to 1200 tons, this series is ideal for automotive panels, appliance shells, elevator components, and electrical cabinet structures.
Designed with a rigid straight-side frame and balanced three-point crank system, the LFE series ensures stable pressure distribution across the entire slide area—minimizing deflection, improving die life, and delivering consistent forming results.
🔧 Key Features
- High Pressing Capacity (400–1200 Tons)
Built for thick plates, wide tooling, and complex forming operations in automotive and industrial fabrication. - Three-Point Crank Drive System
Provides excellent slide guidance and minimizes angular deflection, making it suitable for deep drawing and high-precision work. - Large Slide & Bolster Area
Sizes up to 5000×1800 mm accommodate progressive dies, large part layouts, or multi-station transfer tooling. - Adjustable Stroke & Die Height
Stroke lengths up to 450 mm and die heights up to 1200 mm, suitable for deep-forming dies and tall tooling stacks. - Enhanced Load Support
Upper die weight capacity up to 12,000 kg, with bolster thickness up to 300 mm for maximum rigidity. - Motorized Slide Adjustment
Precise, motor-driven adjustment systems (up to 11×4 kW) enable fast die changes and repeatable height settings. - Side Openings & Working Clearance
Large side openings (up to 1400×1200 mm) for automation compatibility with feeders, robots, or loading systems.
📦 Typical Applications
- Automotive inner/outer panels, crossmembers, and structural reinforcements
- Refrigerator doors, washing machine shells, and appliance side panels
- Elevator cabins, guide rails, and frame profiles
- Large switchgear enclosures and electrical panels
- Progressive die stamping with wide-format sheet materials
🔩 Optional Add-ons
