LFM Series Multi-Point Straight Side Press Machines (110–800 Ton)

The LFM Series Multi-Point Straight Side Press is a high-performance mechanical press solution designed for precision forming of medium to large-size parts. With capacities ranging from 110 to 800 tons, the LFM series is widely used in automotive, appliance, hardware, and electronic industries, supporting progressive die stamping, deep drawing, and multi-cavity forming.

Key Features

Multi-Point Pressing System (2 or 3 points)
Ensures even distribution of force across the entire slide area, reducing die wear and improving product accuracy.
Wide Range of Capacities & Stroke Options
Tonnage from 110T to 800T with stroke lengths up to 350 mm, allowing flexibility for various forming processes and die structures.
Large Bed & Slide Configurations
Bolster and slide areas up to 3600×1400 mm, ideal for mounting progressive dies, large frames, or multi-cavity tooling.
High-Speed Operation
Stamping speeds from 15 to 65 SPM meet the demands of high-volume production lines while maintaining stable forming quality.
Precision Adjustment & Die Height Control
Equipped with motorized slide adjustment (up to 7.5 kW) and die height settings up to 700 mm, ensuring fast and accurate die changes.
Robust Frame & Side Opening
Rigid frame construction with side openings up to 1100×700 mm, suitable for material feeding systems and automation integration.
Integrated Die Cushion System
Standard double-cylinder die cushion with capacities up to 14×2 tons, enhancing deep drawing performance and blank holding control.

Application Scenarios

Automotive structural components (brackets, floor panels, cross beams)
Electrical appliance shell and door frame forming
High-speed stamping for hardware and electrical terminals
Progressive die operations for large-format or multiple-part layouts
Deep drawing of aluminum or stainless-steel parts

Optional Configurations

Moving bolster system (hydraulic or servo type)
Die height digital readout with auto memory
Pneumatic or hydraulic die lifters and clamps
CE or UL certified control systems with touch-screen HMI
Integration with servo feeder, decoiler, and robot transfer lines
