When sourcing a plate counting machine, you must prioritize counting accuracy (ideally ≥99.9%) and processing speed, which should align with your production line requirements (e.g., 50-200 plates per minute). Key technical components include high-resolution optical sensors or CCD cameras for vision-based systems, and PLC control systems (such as Siemens or Delta) for stable operation. Ensure the machine supports adjustable track widths to accommodate various plate diameters and materials, whether they are plastic, paper, or ceramic.
