Old paint gets caught up on the edge of the injection point, as a result of their design which opens slightly towards the mold. These areas do not experience shear forces and are difficult to reach and clean. Pigment gets caught and is released during the injection.
Fixing the mold and improving the surface area and heating at the injection point.
Using a designated RAMCLEAN® cleaning product, and following the Injection Cleaning Procedure.
Cleaning tip – we strongly recommend cleaning the screw prior to cleaning the mold. Next, clean the mold and injection point after heating by an additional 15-20 degrees.
