      Nominal Shrinkage, Injection Molding

    Shrinkage Factors:
    The shrinkage values provided below were obtained iwith simple plaques and are reported as nominal values. These values should be considered estimates given that resin shrinkage is influenced by several factors including part geometry, mold design, molding conditions, part cooling during and after molding. Consequently, the values given below cannot be used as absolute.

    Shrinkage Verification:
    Given that shrinkage is affected by many factors, it is the user’s responsibility to verify the shrinkage for their own mold design and molding conditions before cutting tool steel. If a similar tool is already present, run the material on this tool with normal process and handling conditions and determine the shrinkage. If such a tool is not available, finish only one core and cavity using estimated shrinkage values, staying steel safe. Based on the shrinkage measurements of parts from this core/cavity combination, make the necessary adjustments to the shrinkage factor before cutting additional cores and cavities. Remember to wait at least 48 hrs before measuring shrinkage. Also, be aware the heat aging (or annealing) after molding can affect shrinkage.
    Conditioning after Molding:
    • 48 hr at 23°C
         		Nominal Shrinkage:
    • 1.3 to 1.5% (0.013 to 0.015 in/in)

    The above test results are based on 150 x 90 x 3mm edge gated plaques (1 mm gate).

      Molding Guidelines

      General Processing Conditions for:  Injection Molding
    • Rear Temperature: 350 - 390°F (145 - 200°C)
      Middle Temperature: 410 - 455°F (210 - 235°C)
      Front and Nozzle Temps: 410 - 455°F (210 - 235°C)
      Stock Temperature: 400 - 500°F (205 - 260°C)
      Mold Temperature: 73 - 120°F (23 - 50°C)

    • Suggested shot size: 50 to 70%
      First stage injection pressure: Maximize
      Screw speed: 30 to 60%
      Packaging pressure: Minimize
      Back Pressure: 50 to 150 psi

      Other Molding Considerations:
    Dispersion of color concentrates is improved when using a screw with a mixing zone or a mixing nozzle. Even though specific applications may require conditions outside of the given general guidelines, melt temperature above 500°F (260°C) may cause resin degradation and changes to resin properties.
