In the realm of precision stamping, the use of molds with alignment pins is paramount. These pins play a vital role in rectifying the material’s length inserted into the mold during each cycle, ensuring the accuracy of the stamping production. To achieve impeccable correction, the servo feeder must incorporate a relaxation mechanism. This relaxation mechanism is engaged when the alignment pins are securely positioned within the stamping material. It is during this phase that the servo feeder clamps the material in a relaxed state. This critical moment allows the alignment pins to promptly rectify any disparities, and it corresponds to what we refer to as the servo feeder’s relaxation angle.

The Art of Precise Installation and Adjustment

Our proficient technical team, well-versed in installing and fine-tuning servo feeders during trial runs, meticulously fine-tunes various aspects of the servo feeder. These aspects include the feed height, feed angle, and relaxation angle, all tailored to match the specific molds employed in the trials. Following the initial single-stroke testing, continuous stamping ensues to verify that the stringent precision standards are consistently met. Moreover, we impart comprehensive training to the operators of the stamping press servo feeder production line. This training equips them with the adept skills needed for the optimal utilization, calibration, routine maintenance, and repair of the servo feeder equipment.

Unveiling the Common Oversight

However, despite the proven reliability of servo feeders, practical applications often reveal a common oversight among operators. This oversight pertains to the adjustment of the servo feeder’s relaxation angle. This lapse frequently occurs when a new mold is introduced to the press. The operators’ focus is understandably fixated on adjusting the servo feeder’s feed height, given its immediate relevance due to the mold change. Unfortunately, this oversight leads to imprecise feeding, causing frustration among operators who grapple with identifying the underlying issue. Consequently, doubts about the servo feeder’s efficacy arise, fostering the misconception that it is tailored exclusively for specific molds. In reality, this perception stems from the inadequate adjustment of the servo feeder’s relaxation angle.

Deciphering the Importance of Relaxation Angle

At this juncture, many stamping proprietors may wonder about the significance of such precision in the relaxation angle, particularly when the servo feeder’s feed angle generally ranges from 270 to 350 degrees. Allow me, as an experienced manufacturer of servo feeders, to clarify this matter for our esteemed clientele. The rationale behind this complexity is remarkably straightforward: each set of molds entails distinct stamping processes. As a result, factors like mold thickness and alignment pin length introduce variations in the alignment pins’ insertion time into the material. If not addressed by adjusting the relaxation angle, this temporal discrepancy hinders the material clamping’s effective relaxation. Consequently, the alignment pins’ corrective role is compromised, leading to inaccuracies in feeding length. Thus, recalibrating the servo feeder’s feed angle becomes a pivotal procedure after mold replacements. The optimal adjustment entails allowing the servo feeder to relax when the mold’s alignment pins penetrate the material orifice, and the mold begins its ascent before the alignment pins fully emerge from the material pinhole. This methodology stands as a cornerstone for validating the high-accuracy stamping precision achieved within the press.


In the realm of precision stamping, achieving optimal accuracy requires an intricate interplay of various factors. The alignment pins and the servo feeder’s relaxation angle emerge as key components that demand precise adjustment to ensure impeccable feeding length. By understanding the nuanced relationship between these elements and embracing meticulous adjustments, stamping operations can consistently achieve the pinnacle of accuracy and efficiency. As leaders in the field of servo feeders, we are committed to not only providing top-notch equipment but also sharing insights that empower stamping professionals to elevate their craft and exceed industry standards.
