Compounding: Efficient Equipment,
Lean Trends
New designs and controls allow for faster, more efficient, and
even safer compounding extrusion

By Jennifer Markarian

T

hermoplastic compounding-whether performed by
a resin producer, toll compounder, specialty compounder, masterbatch compounder, or processor
using direct compounding of raw materials to finished part-
is a crucial step in creating a material with the performance
required for an application. Additives such as antioxidants,
property modifiers, fillers, colorants, and fiber reinforcements must be accurately dosed and effectively blended
without damaging the additive.

Equipment suppliers continue to provide improvements
in output rate and energy consumption and to optimize
features such as gentle mixing for sensitive materials, feeding for low bulk-density fillers, and easy access for cleaning
and quick changeovers. Other trends include ongoing
demand for turnkey or direct extrusion systems, and increasing use of advanced process control and simulation
technologies.

A modular, turnkey compounding system can be built in modules that are shipped to a customer's site for installation
