- and cold-runner systems, the impact of circular and noncircular gates, and a variety of mold cavity designs, including single-cavity, multicavity, and family molds. An option to assign multiplicity factors for mold cavities in order to receive multicavity simulation results from the modeling of only one
Strategies/Operations - Valve Gate Sequencing Strategies, Part II - 09/05
wants can run multiple parts varying in size, that make up the components of an assembly, often referred to as a family mold. All the parts of an assembly should be produced with one shot. This type of mold makes mold balance very difficult to achieve and the cold runner design is guesswork a lot
