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.”
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. New handling equipment is also packed with more electronic intelligence in the form of upgraded software, new touchscreen interfaces, and distributed control functions that eliminate the need for a bulky control cabinet.
In blenders and feeders, a number of new systems are designed especially for handling wood flour, an up-and-coming ingredient for plastic composites. There’s also an emphasis on micro blenders and micro feeders sized for small injection machines. Some new gravimetric blenders claim to be the first batch gain-in-weight types to be able to meter non-free-flowing powders, more usually handled by continuous loss-in-weight blenders. These target increased metering of small amounts of additives directly at the injection press or extruder, possibly reflecting wider use of new mixing screws and new processor-friendly concentrates.
In dryers, one new compressed-air model uses existing technology in a way that’s new to plastics. It’s a patent-pending application of a selective adsorption device used for decades to dry the air in submarines. It claims to be the only compressed-air dryer that guarantees a certain dewpoint level.
Among special handling equipment for wood fiber at NPE, Brabender Technologie Inc. of Mississauga, Ont., will show a new gravimetric feeder for wood fiber and 1-in. fiberglass. Colortronic Inc., Runnemede, N.J., will show the new loss-in-weight Wood Feed System for wood-fiber composite extrusion. O.A. Newton & Sons, Bridgeville, Del., will show new gravimetric feeders for wood flour and carbon black.
Several new gravimetric blenders include the capability to feed powders. Comet Automation Systems in Dayton, Ohio, is introducing the Exact-A-Batch MP blender, a gain-in-weight model that can meter both pellets and non-free-flowing powders. It has a patented powder dispenser for additives such as blowing agents, uv stabilizers, flame retardants, and pigments. It can feed up to two non-free-flowing and two free-flowing ingredients.
Several companies are offering new micro blenders for small machines. AEC/HydReclaim, Fenton, Mich., will show a new mini batch weigh blender with mini additive feeder and new controls for both injection and extrusion. The mini batch blender has removable stainless-steel hoppers for quick material changes.
Novatec Inc. of Baltimore is showing its new NovaBlend 100 gravimetric micro blender for up to four components. Only 7 x 7 in. and 26 in. tall, it blends one or two additives into two main components at up to 100 lb/hr.
Small feeders are also being introduced to add small amounts of powdered additives to injection machines or extruders running medical tubing, wire, and fibers. Colortronic will bring out a more compact version of its Colorblend low-rate powder dosing unit. Called Colorblend S, it is said to offer very accurate disc dosing of small additive amounts.

Maguire Products Inc., Aston, Pa., will introduce a new small size of its Weigh Scale Totalizer. Model WST 110 meters preblended ingredients at the extruder throat to monitor material usage in plants where several machines are fed from one silo. Maguire says it’s the first time that extrusion controls have been incorporated into standard blender controls, eliminating a second scale and controls. This feature is needed for regulating output of one-component extruders on multi-layer film lines.
Among other new gravimetric blenders, Mould-Tek Industries Inc. in Toronto will show its new Exac-U-Batch GXB weigh-scale blender. Colortronic will also show a new gain-in-weight gravimetric blender called Ultra Blend II.

Novatec’s new blender control adjusts additives for each batch based on the actual amount of virgin resin and regrind in that batch, rather than averaging from batch to batch. The new control is available on Novablend 600 and 1200 gravimetric blenders for up to four components and on BBS series blenders for up to eight components.
Comet will show a recently introduced volumetric blender controller, the CT-100, which can be retrofitted to any make of disc-fed blender. It gives readouts of resin usage and controls up to six components and one mixer. The CT-100 software also calculates color based on the amount of regrind used. It senses if the blender runs out of regrind and switches to two-component blending, then returns to three-component operation when the regrind hopper is replenished.
Brabender is also showing new On-Line Feed-Rate Verification software for its gravimetric loss-in-weight feeders. Brabender says this is the first capability to measure gravimetric feed rates “on line.” Weigh scales are verified off-line and the software revises previous weights automatically.
