Suitable for the bulk production of medium and small parts, mainly the suspended plating of nickel, chromium, bronze, silver etc. in the hardware electroplating Industry. It uses hydraulic actuation, stably and reliably running with small noise, and a computerize automatic control system, with the PLC control the whole line, simple and accurate operation, both speed and time can be adjusted and controlled at will upon the various technical requirements of the electroplating technologies. A buffer is set, the part being plated is held tightly, greatly reduce the operators and enhance the electroplating quality. High productivity and great output.
