The new GC Series central chiller from ACS, Schaumburg, Ill. (parent of AEC, Sterling, and Colortronic North America), has modules that range from 20 to 60 tons, allowing processor to add cooling capacity as the need arises, up to 300 tons.
If you never paid much attention to what kind of refrigerant is circulating inside your plastics chillers, it may be time you did.
At the NPE 2009 show in Chicago, half a dozen exhibitors showed new cooling equipment that emphasized improved performance at about the same or lower cost.
A new series of compressed-air venturi hopper loaders comes from ACS Group.
A continuous loss-in-weight feeding system and a gravimetric additive feeder are new from ACS Group, New Berlin, Wis.
Ability to be reconfigured for changing needs is one major design concept behind the new T500 Series central granulators from ACS Group, Schaumburg, Ill., parent of the AEC/Nelmor, Cumberland, Sterling, and Colortronic brands, all of which will offer the new models.
Smaller footprint, energy savings, and enhanced control (including a handheld pendant) are some of the new features of the first “green” chiller from ACS Group, New Berlin, Wis.
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.
At NPE in Chicago, chillers and TCUs were put on a lean energy diet and redesigned for greater durability. Suppliers also added features while taking out cost.
NPE 2006 held no revolutionary changes in dryers, blenders, feeders, loaders, or conveying controls, but widely adopted improvements make the newest models easier to use and maintain—and easier on the budget, too.
Most of the news at the show is in fluid-circulating mold-temperature-control systems.
Dryers, feeders, blenders, loaders, metal detectors, level sensors, mechanical and pneumatic conveyors, silos, bins, pumps, filters, valves, box fillers, bag dumpers, and materials-handling control systems constitute one of the biggest categories of products on display at NPE.
Recent trends to-ward multi-material molding, hard/soft overmolding, and dual-durometer coextrusion create growing volumes of scrap that is difficult or impossible to reuse.
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?
For the second straight NPE show, the focus in compounding is on twin-screw machines that deliver more speed and torque—thus more output—than ever before. No fewer than six suppliers of twin-screw compounders are showing such machines. There’s something to see in in-line systems as well. And there’s plenty of news in PVC mixers and pelletizing equipment, too.
From pneumatic systems that deliver materials to the processing machine to conveyors and handling devices that pull parts out the back, the trend appears to be “smaller and smarter.” NPE 2000 will show lots of downsized auxiliaries designed for mini processing machines, as well as more compact equipment of every size that frees up floor space.
NPE will show higher outputs of practically everything, as advances in grooved feeds, servo drives, screw torque, mixing screws, dies, and downstream cooling, cutting, and handling make everything run faster.
The big show in Chicago presented more new loaders, feeders, blenders, and conveying controls than you could count. They’re more flexible, easier to maintain, and easier to control. Many are web-enabled, and some are lower in cost.
Although the bulk of materials-handling equipment introductions were covered in our June pre-show issue, there were still a number of new developments waiting to be discovered at NPE 2000 in Chicago.
While most of the new granulators shown at NPE 2000 last month were beside-the-press models, there was also an accent on larger units with an appetite for tough hunks of large-diameter PVC pipe, bundles of textile fibers, and wads of molten bottle flash. Many are configured for “difficult” resins from engineering types to soft TP elastomers.
From pneumatic systems that deliver materials to the processing machine to conveyors and handling devices that pull parts out the back, the trend appears to be “smaller and smarter.”
A radically different approach to in-line compounding of rigid PVC can replace a conventional batch mixer with a smaller, continuous, high-intensity mixing system.
A radically different approach to in-line compounding of rigid PVC can replace a conventional batch mixer with a smaller, continuous, high-intensity mixing system. It requires dramatically less space, energy, and processing time. It greatly reduces capital cost for equipment and plant construction by eliminating the need for a mezzanine. And it also greatly reduces the heat history of the resin. It simplifies material handling, allows greater formulating flexibility, saves resin on color changes, and may need only one operator instead of two. It also lets processors add capacity easily, without the high fixed cost of batch mixers.
