Knitting Machine PLC Conversion System – Smart Automation for Modern Knitting

Our Knitting PLC Conversion System is designed to upgrade conventional knitting machines by replacing outdated electrical, mechanical, or relay-based controls with a modern PLC and HMI-based automation solution. This conversion improves machine speed accuracy, fabric quality, energy efficiency, and operator safety, making it ideal for circular, flat, and warp knitting machines.

The PLC conversion enables precise control of knitting operations, real-time monitoring, and faster troubleshooting, helping knitting units achieve higher productivity and consistent output.
