Henli’s independently developed 3-in-1 feeder stamping line delivers four core advantages for automotive door panel production:
-
Integrated High-Performance Design: Centered around a premium 3-in-1 feeder, it handles material widths up to 1600mm and thicknesses from 0.3mm to 12mm. With four specialized models (precision thin, medium-thin, medium-thick, and heavy-duty thick), it seamlessly combines decoiling, leveling, and feeding. This integration simplifies processes, boosts efficiency, and ensures exceptional stability.
-
Ultra-High Precision & Reliability: Feeding accuracy is consistently within ±0.02mm. Equipped with automatic detection systems, it monitors operational status in real-time during stamping, guaranteeing product quality at the source.
-
Smooth Automation & Material Control: The feeder features automatic material arms (hold-down, guide, support) and a hydraulic feeding/leveling system, enabling fully automated material handling without manual intervention. Its innovative horizontal motor-driven hold-down arm dynamically adjusts pressure based on coil changes, preventing material loosening and ensuring smooth, consistent decoiling.
-
Compact Footprint & Modular Flexibility: Occupying minimal floor space, its streamlined design optimizes factory layouts. The modular construction – with the coil unit and feeder head connected via a base plate – offers exceptional flexibility, simplifying assembly, transportation, and adaptation to diverse spatial requirements.
Currently, most domestic stamping lines rely on traditional split systems (decoiler + leveler + feeder or decoiler/leveler combo + feeder). Compared to Henli’s 3-in-1 feeder line, these systems require longer feeding zones, offer lower automation, and deliver inferior leveling/feeding accuracy. They are particularly problematic and limited for medium-thick and heavy-duty thick material stamping – directly impacting production quality and efficiency.
Leveraging over a decade of R&D and manufacturing expertise, Henli’s 3-in-1 feeder stamping line significantly outperforms traditional split lines in overall process maturity, stamped part quality, operational efficiency, and application range. This translates directly to superior stamped component quality and precision, enhancing our customers’ product competitiveness and delivering higher returns.
As a short-process stamping system, the Henli 3-in-1 feeder line operates with high stability and efficiency, featuring a minimal feeding zone. Its automatic feed detection prevents misfeeds, enabling high-precision automated feeding – making it the ideal choice for automotive manufacturers specializing in precision door panel stamping.
