Injection Molding: Fill Based on Volume, Not Weight ...

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.

Should injection molding be the best choice for designers ...

A shot is the volume of material that is used to fill the mould cavity, compensate for shrinkage, and provide a cushion (approximately 10% of the total shot volume, which remains in the barrel and ...

Many questions on residence time and shot volume during ...

If the shot capacity of a machine does not take into account the material in the flights, then how does one calculate accurate residence time? Is shot volume less than 20% of barrel size absolutely to be avoided? Is it best for part performance to select a low MFR material? Mike Sepe, the Materials Analyst of Injection Molding Magazine fame and host of our six-part Injection Molding Expert ...

properties, an appropriate match of shot size, (i.e., volume of cavities, runners and sprue) to barrel capacity is very desirable. A shot weight of 60% to 75% of barrel capacity is recommended. This minimizes melt residence time in the barrel, enabling processing at higher stock temperatures with optimum melt flow while avoiding degradation.

of shot size, (i.e., volume of cavities, runners and sprue) to barrel capacity is very desirable. A shot weight of at least 50% of barrel capacity is recommended. This minimizes melt residence time in the barrel enabling processing at higher stock temperatures with optimum melt flow while avoiding degradation.

Understand What Is High Volume Injection Molding – NUBS ...

High Volume Injection Molding: High Volume Production. Injection molding is the oldest high-volume manufacturing process. This is a special service process that offers full production quality and a range of up to a million numbers of pieces in a month. High volume injection molding gives high tolerance precision and cost-saving.

Calculate Shot Size Vs. Barrel Capacity | Plastics Technology

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.
