Industry:
Injection Molding

Mission:
Increase productivity, and reduce cost

Challenge:

    • Reduce Energy Cost
      • As an example,
        • - 2000 Ton IMM
        • - Operating 3 shifts, 250 days a year
        • - Power usage: 400 KW/h at 0.10 $/KWh
        • - Cycle Time = 60 Sec
        • - 3 Setups per day @40 minutes each
        • - Cost of electricity = $220,000

Solution:

    • Energy Value Stream Mapping (EVSM)
        • In the above example,
          • - if the change over time is reduced to 25 minutes through SMED
          • - If the cycle time is reduced to 50 seconds through Standardization and implementing ideas such as:
            • Reduce the mold open distance
            • Close on the fly
            • Reprogram the robot
          • Then Cost of electricity = $180,000
