• Blenders (non-intensive)

  Spectra metering feeder, a colorant/additive metering system, mounts on machine and precisely augers free-flowing materials into base resins as they flow into machine throat. Variable-speed d-c motor powers a selected metering auger. Metering occurs on a signal from injection or blow molding machine, or in conjunction with extruder speed. Spectra comes with a variety of metering augers from 0.5-in. to 2-in. diam. to vary letdowns in accordance with shot size or extrusion rates and material type. Supply hopper includes quick-cleanout door, and the cast-aluminum auger housing includes sampling port for setup calibration.

  In-line mixer option can increase preblending performance, and a machine throat adapter, which mounts between the machine hopper and machine mounting plate, allows two Spectras to feed simultaneously for nearly instant color changes on the same machine. Stacking another adapter on the assembly provides mounting for four Spectra units.

  Modular gravimetric blending system automatically weighs as it loads itself with one or more pellet or powder materials and weighs minor ingredients as they are metered into a scale hopper. Blending is done in either a supplied dynamic mixer or a separate ribbon or high-intensity mixer. Systems deliver 100 to 8000 lb/hr of blended materials.

  All weigh blenders have ± 0.5% accuracy. Larger models come standard with DX electronic controls, including CRT screen and custom keyboard for recipe entry and storage. Displays include totalization, setpoint recipe, stored recipe, and alarm signals. Optional printers can be supplied, and controls can be interfaced with factory computers.

   

• Chillers

  Direct- or indirect-cooling liquid-temperature controllers in pump sizes from 1/2 to 3 hp and 3-12 kw heating, and solid-state or microprocessor controls.

  The 2000 series portable air- or water-cooled chillers from 2 to 35 tons include NEMA-rated components, solid-state temperature controllers, semi-hermetic compressors, and hot-gas bypass.

  Also process-water systems, including central chillers, pump tanks, and cooling towers. Heat-recovery systems recycle process heat and use it to supplement plant heat during winter.

• Conveying Equipment (pneumatic and Mechanical)

  Basic line of integral-motor hopper loaders, plus complete line of remote vacuum-pump loaders and systems. Self-powered, integral-motor models include solid-state controls and range from 250 lb/hr to over 2000 lb/hr. All models include automatic filter cleaning after each load. Ratio models available for virgin/regrind conveying.

  For higher conveying capacities over longer distances, Command 2000 central vacuum systems and loaders use floor-mounted vacuum pump to provide power for all loading stations. Central dust collector eliminates on-machine filter maintenance. Pump sizes from 3 to 25 hp. Also special twin-cyclone powder loaders.

  Specializes in weigh-loading systems, using Command 2000 equipment, by adding weigh cells to each vacuum hopper and supplying special microprocessor controls with CRT messages. Optional printers can record each pound conveyed.

  Also welded-steel storage silos and continuous level-sensing systems for electronic silo monitoring.

• Conveyors (parts-handling)

  Nearly 30 standard belt-conveyor models, specializing in customized designs and systems. Basic models in 6- to 16-ft lengths. Omni line designed for under-machine or low, pass-along installations; HR line recommended for use with pick-and-place robots. All standard models (many with casters) include V-groove belt tracking adjustment without tools and powered by single-phase, motor/gear-box drives.  Specialized units include Water Bath Conveyor for large part cooling and conveying, Box Boy indexing conveyor, which automatically counts parts as they drop into bags.

  End-of-belt and standalone parts separators can be provided with special diamond-back belting, which allows steep incline, cleatless conveying up to 45° or greater.

  A count-by-weight system allows direct transfer from the mold to shipping cartons through an electronic scale and arrangement of conveying devices.

• Dry Offset Printing Equipment
• Dryers for Resins

  Accudry dehumidifying dryers for critical drying applications, and the 2000 series hot-air dryers for nonhygroscopic applications.

  Ten models of automatic desiccant dryers use a molecular-sieve desiccant to trap moisture within a closed drying system. Several desiccant cartridges are provided, which are periodically indexed to a regeneration cycle. Programmable microprocessor controls provide LCD messages for initial settings and performance data and alarm conditions.

  Hot-air dryers come with an integrated, stainless-steel-lined drying hopper that mounts on the processing machine. Floor-mounted models available. Seven models provide drying ranges from a few lb/hr to more than 1000 lb/hr, depending on material type. An air-flow regulator balances blower cfm for drying efficiency.
