Raw material waste in plastic manufacturing drives up costs and environmental impact. Automation solutions minimize this waste, boosting both profitability and sustainability.
Digitizing the Production Line: Sensor‑Based Monitoring
In a mid‑size polypropylene injection plant, raw material flow was controlled manually, causing a 3‑5% loss of granules during conveyor feeding. Botex System installed flow sensors and a real‑time data acquisition unit that measured granule weight and moisture instantly. The data fed into the PLC, automatically adjusting the feed speed, reducing raw material waste to 0.8%.
Smart Mold Management and Waste Reduction
Temperature fluctuations in injection molds led to defective parts and increased recycling needs. New‑generation thermal cameras mapped mold surface temperatures within seconds. The software generated an optimal temperature profile and sent it back to the machine controller. Defective part rate dropped from 2.5% to 0.6%, and raw material recycling demand fell by 40%.
Integrated SCADA for Energy and Material Efficiency
The plant’s energy consumption, especially in heating and cooling loops, was uncontrolled. A SCADA platform unified energy meters, temperature sensors, and pump flow meters on a single dashboard. Operators monitored real‑time energy usage and disabled unnecessary heating cycles. Annual energy cost fell by 12% and raw material heat loss decreased by 5%.
Key Automation Components
- Flow and moisture sensors – reduced granule loss to 0.8%.
- Thermal camera and temperature control algorithm – lowered defective parts to 0.6%.
- SCADA integration – achieved 12% energy savings and 5% reduction in material heat loss.
