Coating, winding and laser lines from one Dongguan maker
The registered company is 广东省秦田科技有限公司 in Dongguan. QINTIAN's site groups its products into coating and calendering, winding, laser and wrapping equipment. The company page also describes its manufacturing base and its development work; ask for a factory visit or recent documents if these matter to your decision.
The same company name appears on Dongguan's 2024 talent-policy list. That is a local administrative listing. Factory size, current certificates and machine performance are matters to confirm with QINTIAN directly, along with any customer, award or capacity figures shown on its promotional counters.
Tabless cylindrical cells and laser tab cutting
Large cylindrical formats such as 46-series cells often use a full-tab or tabless design. Here the uncoated foil edge is laser-cut into many small flags, which are then folded and welded to a collector disc in place of a single welded tab. Cutting the flags inside the winder saves a separate notching step, but it also ties the laser, the inspection and the winding closely together.
QINTIAN states a production base of 300,000 square metres, more than 300 invention patents and over 500 staff, with ISO 9001, 14001 and 45001 certification. Request copies of the current certificates with your quote. For the integrated machine, ask for the supported cell diameters and heights, the tab-cutting pattern and burr limits, and how the end of the jelly roll is inspected before welding.

What these details mean for selection
The featured machine is the Cylindrical laser cutting and winding integrated machine. It cuts tabs, inspects the electrode and winds it with separator. Its page lists the cell sizes for this machine, which differ from those of QINTIAN's standalone cylindrical winder.
Pin down the integrated machine's format range
Row 363 of Dongguan's 2024 enterprise talent-policy list names 广东省秦田科技有限公司 in Tangxia. It confirms the exact company name in that policy setting. Its enterprise-type column is a policy category; current certificates and equipment acceptance come from QINTIAN's own documents and your tests.
The integrated cutting-and-winding machine has its own size envelope. Send QINTIAN a cell and electrode drawing and ask for the tab construction it supports and the proposed route through inspection, cutting and winding. Quote the integrated machine on its own figures, apart from the height range and transport speeds of the standalone winder.
