U.S. Client On-Site FAT for Electrode Die Cutting Machine
2025-12-17
We’re thrilled to share a behind-the-scenes look at the on-site FAT (Factory Acceptance Test) for our Electrode Die Cutting Machine—hosted alongside our valued U.S. client! This session wasn’t just a routine check; it was a collaborative deep dive into the equipment’s performance in production-relevant scenarios.
During the FAT, our team and the client worked side-by-side to validate capabilities that directly impact their manufacturing efficiency (with real-time data shared for full transparency):
Field-verified cutting precision:Together, we confirmed the finished product accuracy (the metric that actually impacts battery assembly yield):
Electrode tab precision: ±0.2mm (ensures tight fit during battery cell stacking)
Electrode slitting precision: ±0.3mm (guarantees consistent material sizing for mass production)Note: The "±0.02mm-level precision" often referenced in the market refers to mold machining accuracy (the size error of the cutting mold itself), not the actual finished electrode precision (shaped by material properties, tension control, etc. in mass production). Our stated metrics are field-proven results for real manufacturing lines.
Stable operational performance:
We completed 8 hours of non-stop test runs (zero mechanical failures), matching the client’s high-volume production demands.
The servo motor-driven tension system was validated on-site, with tension fluctuation ≤5N—eliminating material deformation during high-speed cutting.
Practical dust reduction:The client witnessed our non-contact dust removal function (applied to both sides of the electrode sheet) in action, confirming it effectively reduces dust generated during punching (a key safeguard for battery safety).
This is just the first phase of our FAT collaboration! In the coming weeks, the client’s team will return to validate other equipment models in the project, and we’ll share those on-site verification updates here.
At Sunive, our FAT process is rooted in production-focused, field-proven results (not just theoretical specs). If you’d like to learn how our Electrode Die Cutting Machine’s on-site verified performance can fit your battery manufacturing line, reach out to our team today.
