Keeping Wax Liquid For Application

"Hot gun" applies masking wax and similar materials in liquid state. Holding chamber and nozzle supply continuous heat to wax, and wax injects directly into hole as liquid. Nozzles of various sizes interchange so one selects nozzle having opening suited to viscosity of wax and size of hole in particular application. Gun fast, eliminates repeated application, and greatly reduces cleanup time. Available commercially for applying hot glue, used to ensure wax penetrates and fills holes, flow passages, and manifold passages so contamination sealed off during manufacturing operations.
