Electrical enclosure production demands uninterrupted material flow for efficient stamping of steel/aluminum casings. Traditional decoilers halt entire lines during material changeovers, creating costly bottlenecks. Henli’s Double-Head Decoiler eliminates this downtime through innovative dual-station design.
How It Transforms Enclosure Manufacturing:
Our decoiler features two center-symmetric mandrels on a rotating platform. While one mandrel feeds material into your stamping press line, operators safely load the adjacent coil. When the active coil depletes, the platform rotates 180° within seconds, positioning the pre-loaded coil into the working zone. This enables:
-
Zero stoppage for coil changes
-
Continuous feeding to downstream levelers or servo feeders
-
30%+ productivity increase for cabinet/casing stamping lines
Precision Workflow for Enclosure Production:
-
Coil Loading (Station A):
-
Position coil on retracted Mandrel 1 using forklift
-
Actuate hydraulic cylinder to expand mandrel segments, securing enclosure-grade steel
-
Engage pressure rollers to guide material head
-
-
Simultaneous Operation:
-
Mandrel 1 feeds material into leveler/feeders for enclosure blanking
-
Load Mandrel 2 with next coil during active production
-
-
Seamless Transition:
-
Upon Mandrel 1 depletion, release platform lock
-
Rotate platform to position Mandrel 2 in work zone
-
Engage support arms and drive coupling
-
Immediate material tensioning into downstream equipment
-
Technical Advantages for Enclosure Makers:
-
Hydraulic mandrel expansion: Secures 3-8T coils without slippage
-
Integrated material guides: Prevents scratches on pre-painted metals
-
Rotary encoder control: ±0.5° positioning accuracy
-
Bypass traditional 20-30min changeovers
This continuous feeding solution ensures your enclosure stamping presses operate at maximum utilization – critical for meeting bulk orders of server racks, junction boxes, and industrial cabinets.
