Injection Molding Processing Recommendations

General Recommendations

  • Rear Temperature: 350 - 440°F (176 - 227°C)
  • Middle, Front, and Nozzle Temps: 410 - 470°F (210 - 243°C)
  • Stock Temperature 375 - 500°F (191 - 260°C)
  • Mold Temperature: 100 - 160°F (38 - 71°C)
  • Suggested shot size: 50 to 70%
  • Maximize first stage injection pressure with fast fill rate preferred.
  • Screw speed 30 to 60%
  • Minimize the packing pressure.
  • Back Pressure 50 to 100 psi.
  • To achieve good dispersion of color concentrate it is recommended to use either a screw that has a mixing zone or a mixing nozzle.

Considerations

The above conditions are general recommendations. Specific applications may require conditions outside of the given ranges. Melt temperatures above 500°F (260°C) may cause resin degradation and changes to resin properties.

Critical Notice

Shrinkage Factors

The shrinkage values provided in the table below were obtained in a laboratory setting with simple plaques and are reported as nominal values. They should be considered as estimated values only since resin shrinkage is influenced by several factors. The most common influencing factors include resin characteristics, part geometry, mold design, molding conditions, part temperature upon ejection from the mold and part cooling afterwards. Consequently, the values given below cannot be used as absolute.

Determining Shrinkage

Since shrinkage is affected by so many factors, it is the user’s responsibility to confirm the shrinkage for their own mold design and molding conditions before cutting tool steel. For the user to determine shrinkage, the suggested procedure is to finish only one core and cavity using these estimated values (staying steel safe). Based on the measurements of parts from this single core/cavity combination, the shrinkage factor can then be adjusted to fit the particular situation. A second iteration of mold changes (and costs) should be considered and applied after initial shrinkage factors are determined. If a similar tool is already present, run the material on this tool with normal process and handling conditions and determine the shrinkage. Remember to wait a full 72 hours for maximum shrinkage. Also, be aware the heat aging after molding can affect shrinkage.

Nominal Shrinkage Value

The test results below are based on 150 x 90 x 3 mm plaques, edge gated, 1 mm thick gate.

  • Conditioning after molding: 48 hr at 23°C
  • Shrinkage: 0.2 - 0.4% (2 to 4 thousandths inch/inch)
