Multiple Dies Operations

Multiple Dies Operations

Industry:
ALL manufacturing operations that use multiple dies or molds on the same machine such as Injection Molding, Metal Fabrication, Packaging, CNC machine shop

Mission:
Increase available time, increase business and reduce cost

Challenge:
As an example,

    • A 1500-ton injection molding press is used to produce 3 different parts (3 different molds)
    • The weekly requirements for each part are produced in 40-hour runs each
    • The die-change over is about 2 hours each
    • To keep up with the requirements, the machine is run 6 or 7 days a week and the factory carries high inventories of parts

Solution:

    • SMED (Single Minute Exchange of Dies)
      • Convert “Internal” work to “External” work
      • Standardize
      • 5S
    • The die change over for a 1500-ton press was reduced to 20 minutes
