AI Enabled Footwear Manufacturing

Shoe manufacturing involves melting rubber and pouring it into preheated molds to form soles. Maintaining optimal temperatures is critical—underheating causes incomplete filling, leading to defects, while overheating results in overburn and wasted material. An AI and IoT-based solution can optimize this process by using temperature sensors and real-time data analytics. IoT sensors continuously monitor the molten rubber and mold temperatures, sending data to an AI system that dynamically adjusts heating parameters. AI models analyze historical patterns to predict and prevent defects, ensuring precise temperature control. This automation reduces raw material wastage, minimizes electricity consumption, and enhances product quality. Additionally, predictive maintenance alerts prevent overheating-related equipment failures, improving efficiency and sustainability in shoe manufacturing.

Monitoring Water Quality & Quantity

The Pain

  • Molten rubber and die temperatures should meet for proper formation of footwear.
  • Often the heaters exceed or recede temperature thresholds leading to overburn of the rubber or improper shape of the product.
  • Overburn leads to removal of die from the process, scrubbing, and loss of time.
  • Raw material and production time are significantly lost.

The Solution

  • Non-contact temperature sensors were deployed to sense the temperature of the die and the molten rubber.
  • Current sensors were deployed on the heater coils.
  • A motorized valve was channelized into the molten rubber nozzle.
  • All sensors and the valves were connected to our IoT controller and eventually to our IoT platform.
  • The controller takes charge of controlling the process. It takes configuration settings from the web platform.

Benefits

  • 7% reduction in wastage of raw material.
  • Reduction in loss of production time.
