Injection Molding: Fill Based on Volume, Not Weight ... Aug 01, 2018 · Somewhere between 90 to 99.9% full—based on volume, not weight. Factors that influence this are the type of part, number of cavities, balance of filling, a weld line at the end of fill, a living hinge, etc. Bottom line for 99% of parts being molded: The first-stage part (s) should be visibly short, not full with sink.

Calculate Shot Size Vs. Barrel Capacity | Plastics Technology Sep 30, 2011 · If the part, runner (cold), and sprue together weigh 164 g, the equivalent is 182.2 cc of PP (at 0.90 g/cc density), or 6.16 oz (1 cc = 0.0338 oz). Assuming you have a barrel capacity of 8 oz, you might be tempted to conclude that you have plenty of shot volume. Unfortunately this is where things start to unravel. Author: John Bozzelli
