SummaryThe supplier is identified as a manufacturing factory in Yushui District, Xinyu City, China, producing alloy carbon steel bandsaw blades. It reports production equipment for punching, grinding, sawing, quenching, shearing, soldering, and polishing, with finished-product inspection instructions that are uniformly followed. The supplier supports customization from samples, designs, and full or minor customization, and provides ODM and OEM services. Quality processes include quality assurance, complaint-handling procedures, corrective and preventive action procedures, and raw-material traceability.
