Injection Molding: Understanding Pressure Loss In Injection.

In Scientific Molding procedure, parts are filled 90% to 99% in the first injection stage: That is, we make a short shot. If the part is short we know the plastic pressure at the end of flow is zero. We also know the pressure in the nozzle from the reported or calculated plastic pressure.

Make Your Own Injection Molding Machine | Make:

Two little blocks of 6061 aluminum make up the halves of the mold. First, two 0.124″ holes are drilled through both blocks to hold guide pins that will ensure the mold halves are properly aligned. Two ⅛” guide pins are pressed into one half of the mold, and the other holes are reamed out just slightly to 0.126″.

Processing guidelines for injection molding of thermoplastic.

Set injection speed to achieve a fill time of 0.5 to 1.5 seconds. 7. Set shot size to achieve a short shot. 8. Increase shot size until part is 95% filled. 9. Note the injection pressure required to maintain 95% fill of the part. 10. Set injection pressure to 21 to 28 bar (300 to 400 psi) above the injection pressure deter mined in the previous.

A New Look at Evaluating Fill Times For Injection Molding.

We theorized that the injection pressure might also be back-calculated for any fill time using the 2 Point Rheology Curve methodology. It was found that this method was within very reasonable limits of calculating fill pressure vs. actual pressure in most cases, regardless of differing cavitation, melt-delivery system, or plastic material.
