Die Plate Wear Protection Doubles Service Life - A new development in wear prevention on underwater pelletizer die plates is opening up the way to significant reductions in production costs, in particular for the production of polyolefins. This new wear protection is now available for the first time for the die plate of an increased capacity underwater pelletizer for throughputs of up to 70 t/h.

Loss-in-weight (LIW) or gravimetric feeders are devices that directly measure a material's weight to achieve and maintain a target feed rate, which is measured in units of weight per time, such as pounds per hour. This article outlines several key areas where you can optimize the performance of a feeder for your batch or continuous process.

Feeding in a Closed System
Kunststoffe International, 1-2/2016
In a gravimetric feeding system that is closed off and independent of environmental atmosphere, pressure variations inside the material feed hopper may lead to weighing errors. This has a negative impact on product quality as well as production costs. The newly developed electronic pressure compensation (EPC) system offers a reliable and cost-effective solution to solve this problem.
Compounding of Polycarbonate: Advantages of the Co-Rotating Fully Intermeshing Twin Screw Compounding Extruders Technology
Plastics Technology Magazine, 6/2015
The co-rotating, fully intermeshing twin-screw extruder is the primary production unit for compounding of polymer based materials. Coperion has delivered its first co-rotating, fully intermeshing twin-screw compounders type ZSK for compounding of Polycarbonate more than 30 years ago and has meanwhile the largest population of extruders for manufacturing polycarbonate as well as for compounding polycarbonate, e.g. alloys with ABS or filled with glass fibers, talc or pigments.
Black and Finely Dispersed - Compounding Carbon Black Masterbatches for Polyester Fibers
Kunststoffe International, 6-7/2015
A carbon black masterbatch used for coloring polyester fibers has to fulfill high standards, especially if the intended results are filmy spinning fibers for very soft and comfy textiles. Taking a Coperion twin-screw extruder as exemplary, it is shown how screw configuration and processing parameters affect the dispersability of carbon black and material degradation in the polyester matrix.
Accurately and safely dispensing pharmaceutical and high-value powders with an automated loss-in-weight feeder
Tablets & Capsules
This article explains how an automated loss-in-weight feeder can accurately and safely dispense pharmaceutical and other high-value powders in continuous feeding and batching applications, eliminating the dangers and inefficiencies of conventional manual loading.
Food Processing Equipment Trends
Western Food Processor
Today’s food manufacturers are looking for ways to boost production runs, simplify cleanup and sanitation, control ingredient costs, reduce changeover times between runs and increase the ability to produce a variety of product types and sizes, all with an emphasis on cutting cost but improving overall food safety. Automation of the complete process is a key trend in food manufacture from raw ingredient receipt and transfer, including various pneumatic transfer options, batch weighing techniques, and continuous feeding methods, all the way to the extrusion, and packaging steps downstream.
