Materials Handling: Networked Metal Separators Ready for Industry 4.0
Sesotec metal separators incorporate OPC-UA communications protocol.
At October’s Fakuma show in Germany, Sesotec GmbH ( U.S. office in Bartlett, Ill.) presented for the first time its Protector, Rapid Pro Sense, and GF metal separators with OPC-UA communications protocol integrated into their controls. These systems detect and separate magnetic and non-magnetic metal particles, even embedded within plastic pellets or regrind.
OPC-UA (Open Platform Communications-Unified Architecture) is becoming an international standard for “smart factories,” or Industry 4.0. With OPC-UA, these metal separators can communicate with central plant computers or directly with injection and blow molding machines and extruders to protect against damage and clogging of mold and die channels.
Loss-in-weight feeders are the most important piece of auxiliary equipment for compounding extruders.
Is one type of resin dryer faster or more energy-efficient than another? That question prompts competing claims from suppliers—but very little concrete data. When one vendor performed controlled tests to get some answers, its results, published here for the first time, prompted further debate about the difficulties of making valid comparisons and the many complex issues involved in dryer selection.
Processors today face bewildering choices of at least five basic types of dryers, whose capabilities are subject to conflicting claims from equipment suppliers. For the buyer, the most basic questions are: How much drying is needed for the job and which dryer types are up to the task?
