Salvagnini P2lean II

The P2lean II is the second generation of Salvagnini's compact lean panel bender line. Key improvements over the original P2lean include updated MAC2.0 programming software with enhanced collision detection and faster sequence generation, revised blank repositioning mechanics for higher bending speed, and improved integration interfaces for automated blank feeding from the S4 warehouse. The P2lean II also introduced enhanced diagnostics and remote monitoring via the Salvagnini IoT platform. Mechanically, the core panel bending blade concept is unchanged from the P2lean, but cycle times for typical small panel parts improved by approximately 15-20% due to faster repositioning motion profiles.

The P2lean II can process blanks as small as 100 x 100 mm (approximately 4 x 4 inches). Small blank handling is actually a key strength of the lean panel bender: the automatic blank repositioner grips small parts securely without requiring operator skill to position tiny parts on a press brake backgauge. For very small blanks (under 150 mm in any dimension), the operator should verify grip clearance with the bending blade tooling to ensure the blank holder can engage without fouling the blade travel path.

Yes. The P2lean II is rated for 0.5-2.5 mm stainless steel (304 and 316 grades are standard; duplex stainless up to 2.0 mm is possible depending on yield strength). Stainless requires increased bending force due to higher yield strength and work-hardening tendency, and springback compensation values differ from mild steel. The MAC2.0 programming system includes material libraries with stainless-specific springback parameters. Surface scratch sensitivity of stainless is managed by the machine's non-marring blank gripper pads, which are standard on the P2lean II specifically because stainless and brushed aluminum surface quality must be preserved through the bend sequence.

The P2lean II accepts flat blanks from any upstream cutting process: laser (fiber or CO2), turret punch press, plasma, or waterjet. Integration levels: (1) Manual load — operator places cut blanks on the input conveyor; (2) Conveyor link — automated conveyor carries blanks from the laser or punch output directly to the P2lean II input without operator transfer; (3) S4 integration — Salvagnini's automated sheet metal warehouse feeds blanks in programmed sequence to the P2lean II, enabling unmanned overnight runs. The P2lean II is brand-agnostic for upstream cutting — shops running Trumpf, Amada, Bystronic, or Prima Power lasers can feed the P2lean II without special adaptation.

For multi-bend small panels (4+ bends, parts under 600 mm): P2lean II wins on throughput and consistency. Press brake operators must manually pick up and reposition the part for each bend — 4-8 operator touches per part. P2lean II: zero operator touches between blank load and part unload. Cycle time for a typical 6-bend electrical box (300 x 200 x 150 mm, 1.5 mm steel): press brake with skilled operator — 90-120 seconds; P2lean II — 20-30 seconds. For simple single-bend parts (flanges, brackets, channels): press brake is more economical — no programming overhead, setup is faster, and the throughput gap shrinks. The P2lean II delivers the greatest advantage in high-mix high-volume environments where the part mix is predominantly multi-bend small enclosures.
