process optimisation for
powder coating compounders
Our experienced engineers can offer advice on screw profiles and process optimisation including barrel temperature profiles, mixing, intake or feed throat problems or complete screw profile changes for new products.
Feeding or intake: Feed bulky powders and low bulk density or “sticky” extenders without difficulty. We have a number of processing solutions to help you, including our own design of "high intake” feed screws
Under mixing:un-melted polymer or poor dispersion of pigments and additives can be costly, alternative screw profiles with high shear mixing elements can help
Over mixing: Product is too hot, and possibly degraded – Changes to operating conditions or screw profile may be necessary
Discharge melt temperature too high or too low, do you have a worn discharge screw or too many reversing mixing elements?
Solutions for:
- Low output limits
- Feeding or intake limits
- Reprocessing of fines
- Poor dispersion
- Gel bits or pin holes
- Discharge problems
