Abstract
Disclosed is a method of placing a measured amount of tracer material into a release agent solution so that the concentration of tracer material in the release agent as applied to a mold surface is an indication of the amount and distribution of the release agent on the mold surface. The release agent can be applied and/or re-applied until the amount of the tracer material reaches a predetermined value. In the embodiment disclosed the tracer material is a UV dye which will re-emit light when activated by a UV light source and the intensity level of the re-emitted light is a function of the amount of release agent applied. Curing of the release agent preferrably taken place after each layer in multiple layer applications. Also disclosed is a spray head (12) connected to a source (20) of release agent with UV dye therein for coating a mold surface (28). A source of UV light (30,32) activates the UV dye to re-emit visable light which is measured by a photometer (34) to practice the above method. Also disclosed is a method and apparatus by which release agent degradation can be detected and corrected before the release agent is applied to the mold surface. Also disclosed is a completely automatic release agent application cell wherein a release agent spraying robot (10) and a traveling oven (62) automatically processes mold surfaces with a release agent under the operation and control of a computer (64).
