Upstream extrusion equipment includes the TrueWeigh gravimetric
extrusion control, TrueBlend EXT precision extrusion blender, which integrates extrusion control, TrueWeigh continuous blender and the ScrapSaver filmscrap reclaim system.
But at least the tests give processors a better idea of what they want from gravimetric blenders.
Hanna Color, Automotive in Norwalk, Ohio, had suggested that Saturn was using too much color on trim parts and should look at gravimetric batch blenders to save money.
Upstream extrusion equipment includes the True Weigh gravimetric
extrusion control, TrueBlend EXT precision extrusion blender, which integrates extrusion control, and the ScrapSaver film-scrap reclaim system.
One is the Exako gravimetric
direct-dosing device for use on injection machines.
Accessories include blenders, air chillers, treaters, web guides, gravimetric
extrusion-control systems, automatic transverse direction gauge-profile control system and layflat-width control systems.
a screw feeder--examine the accuracy of each feeder in volumetric mode to see the inherent accuracy of the feeding mechanism, separate from the ability of the gravimetric
controls to dampen system instabilities.
Accessories include blenders, vacuum loaders, air chillers, treaters, web guides, gravimetric
extrusion-control systems, automatic transverse-direction gauge-profile control system, layflat-width control systems, and frostline height control system.
Single- and twin-screw extruders; screws; high-speed winders with a unique cutting mechanism for cutting most materials and to prevent fold-over; unwinds; automatic microprocessor-based controls; temperature and pressure controls; digital d-c drives; laser and nuclear gauges; central consoles for monitoring remote operations from a single location; blown-film dies and low-pressure air rings; low-friction blown-film collapsing frames; manual, hydraulic and continuous screen changers; gear pumps and "Geartruders"; static mixers for improving melt-stream uniformity; double-shell, spirally baffled cooling and heating rolls; gravimetric
feeders and blenders; water chillers; and optical web-inspection systems to detect flaws such as specks, pinholes and printing defects.
blending systems will be a major presence among the materials-handling exhibits at this year's show.
