An automated stamping production line, a marvel of modern manufacturing, comprises five vital stages: uncoiling, leveling, feeding, stamping, and recoiling. This seamless procession of tasks metamorphoses raw coil material into usable, refined products or semi-finished goods.

Unveiling the Stages of Automated Stamping Production

Each phase in the automated stamping production journey corresponds harmoniously with specific processing equipment: a decoiler for uncoiling, a leveler for leveling, a feeder for feeding, a press for stamping, and a recoiler for recoiling. Notably, the decoiler stands tall as a distinct equipment category. It not only kickstarts the uncoiling process at the production line’s inception but can also be strategically positioned at the line’s end to facilitate efficient recoiling. Although diverse types of decoilers exist, their central role, whether for uncoiling or recoiling, is unequivocal.

Uncoiling and Recoiling: Two Sides of the Decoiler’s Coin

Uncoiling revolves around unwinding and flattening the coil strip itself, while recoiling necessitates delicately winding the strip onto the decoiler’s material support plate post its release from the press. During the transmission process, tension fluctuations often occur during recoiling. Solely relying on the decoiler’s inherent pull might lead to loosely wound and less resilient strips, thereby compromising recoiling quality. Hence, the decoiler’s role as a recoiling instrument becomes pivotal in production line configuration. A vital factor to consider is whether the stamping customer intends to recoil scrap material or finished products.

Decoilers for Scrap and Finished Products Recoiling

When recoiling involves scrap material, the stringency of winding effects, resilience, aesthetics, and compression levels are relatively lax. In such instances, employing the decoiler directly for recoiling suffices. However, when recoiling processed finished goods, the decoiler’s solitary control over tension proves inadequate. This often results in recoiled products falling short of packaging or subsequent usage standards. To mitigate this, a tensioning machine must precede the decoiler. This mechanical marvel ensures consistent tension during the stamping material’s recoiling process. With unwavering tension guaranteed by the tensioning machine, the recoiling strip adheres snugly to the material support plate. This fundamental adherence guarantees recoiled products’ tautness, aesthetic appeal, and resilience, upholding the quality of these final items.

Unfolding the Recoiling Process

For recoiling, a powered decoiler is the staple choice; non-powered counterparts are unsuited for this task. Regardless of a tensioning machine’s presence, the recoiling decoiler’s operation remains consistent and remarkably straightforward. To prepare, one adjusts the decoiler drum’s expansion and contraction to achieve the desired inner diameter for recoiling. Positioning the A-type iron based on the recoiling strip’s width follows this step. Subsequently, the strip drawn from the press or tensioning machine is secured onto any material support plate, and finally, the “forward” button on the decoiler’s electronic control panel is pressed. If the strip maintains tautness after around 5-6 recoiling rounds, auxiliary machinery along the production line can be triggered to initiate continuous automated processing.


Automated stamping production lines, guided by the intricacies of each process and the influential decoiler, exemplify the pinnacle of manufacturing efficiency. From unwinding coils to recoiling finished goods, this orchestrated symphony of actions ensures the creation of impeccable products, setting a high standard in the world of modern manufacturing.
