Injection Molding: How Backpressure Adjustments Influence

Mar 29, 2018 · But thats not the case. Yes, the parts are full, but not because of an increase in melt temperature or lower viscosity, but because more plastic is packed (at higher density) into the same shot size (see illustration p. 36). If density is higher, there is more plastic in the same volume or shot size.

Injection Molding Process, Defects, Plastic

The amount of material that is injected is referred to as the shot. The injection time is difficult to calculate accurately due to the complex and changing flow of the molten plastic into the mold. However, the injection time can be estimated by the shot volume, injection pressure, and injection power.
