Estimating the term…
Disclosed herein is an injection mold for production of marbled moldings, including at least one hot runner, a cavity, an entry opening into the injection mold and an inlet into the cavity, where the hot runner has at least two ducts that are connected at a first end of each duct to the inlet into the cavity and at a second end of each duct to the entry opening into the injection mold, where the at least two ducts each at least partly form a spiral, and the at least two ducts are bounded by a one-piece component. Further disclosed herein is a process for producing the injection mold and a process for producing marbled moldings.
An injection mold for production of marbled moldings, comprising
A process for producing an injection mold for production of marbled moldings, wherein the injection mold comprises at least one hot runner, a cavity, an entry opening into the injection mold and an inlet into the cavity, wherein the hot runner has at least two ducts that are connected at a first end of each duct to the inlet into the cavity and at a second end of each duct to the entry opening into the injection mold, wherein the at least two ducts each at least partly form a spiral and the at least two ducts are bounded by a one-piece component, wherein the at least two ducts are separated from one another between their first end and their second end by the one-piece component, wherein the at least two ducts each have a center axis, and the center axis is arranged in the form of the spiral around a longitudinal hot runner axis, and the spiral has different slopes at each of at least two different positions, wherein the at least two ducts are configured to counteract homogeneous mixing, and wherein the one-piece component is produced by an additive method.
