LHA-1400P+ Intelligent Flexible Panel Bender for Automated Sheet Metal Production
LHA-1400P+ INTELLIGENT FLEXIBLE PANEL BENDER
Precision bending, self-corrected in real time.
The LHA-1400P+ pairs universal tooling with a 15-axis all-servo control system that senses material variation and compensates automatically — so every bend holds the same angle, part after part.

01 Product Overview
Automatically Compensated, by Design
A multi-axis, all-servo concurrent control system works with load-offset detection and sheet-thickness sensing to continuously correct for variations in material and working conditions in real time.
The result: less waste, less rework, and a bending process that stays stable from the first part to the last — at low energy consumption, which helps contain operating costs across the range.
Lower Cost per Bend, Downstream Too
Because bend quality stays consistent over time, robotic welding, assembly, and finishing run faster — with fewer fixtures, less touch-up, and more stable cycle times.
Lower energy and consumables, shorter changeovers, and a reduced cost-per-bend, whether the job is high-mix/low-volume or a large production series.
02 Connected Manufacturing
Every LANHAO panel bender operates as part of an intelligent production environment — standalone, or fully networked.
|
ERP / MRP Integration Standalone benders integrate natively via software with upstream and downstream work centers, exchanging real-time data with your factory ERP/MRP system. |
Cloud O&M Platform Monitor equipment status in real time from a cloud-based operations and maintenance platform, with full, customizable oversight of production. |
Robotic-Arm Ready Pair with self-driven robotic arms to sequence loading, handling, and bending — supporting lights-out, reduced-labor, just-in-time operation. |
