Abstract

Disclosed, amongst other things, is a melt distribution apparatus of a hot runner and a related method for balancing melt flow to a plurality of drops. The melt distribution apparatus includes a plurality of chokes with each choke of the plurality of chokes being associated with a corresponding one of a drop of a plurality of drops. Each choke of the plurality of chokes being configured to contribute, during an injection of a molding material therethrough, a choke melt-pressure loss such that the plurality of chokes contribute an aggregate choke melt-pressure loss that is generally between 10% and 75% of an aggregate hot runner melt-pressure loss.
