By implementing a chemical purge, the use of virgin resin in the machine cleaning process was reduced, preventing part contamination. Each purge requires 50 pounds of virgin resin, and with 4 purges conducted per week, unnecessary consumption of 10,400 pounds of resin is avoided annually.Considering that resin costs $0.20 per pound, the annual economic savings reach approximately $2,080, representing a direct improvement in material costs and contributing to process efficiency.
