If you’re running pounds of resin through the barrel and mold until it comes out clean, this wasteful process will cost you time and create decreased profit margins. The right purging compound will turn much of that unwelcome expense back into output. Slide’s purging compounds speed up resin-to-resin and color-to-color changes, maximizing your productivity and decreasing the costs. Read More...
There are typically two (2) types of purging compounds:
A mechanical purging compound is effective for numerous applications. As the name suggests, mechanical purging relies on shear force and the differences in viscosity to clean molds. There is no chemical reaction and no soak time needed to purge the molding machine.
A mechanical purge may not be effective in sections of the barrel, screw, or manifolds where there is low pressure. In such cases, a chemical purge is the best choice for cleaning. Instead of shear force, a chemical reaction takes place when the purge contacts the resin or carbon. Some chemical purging agents require no soak time while others require up to 30 minutes; this soak time depends on several factors, such as the resin, size of barrel and screw, manifold size, etc.
