Gravimetric blenders for precise dosing

The new GraviMax gravimetric blenders from Wittmann employ a proprietary three-level blending process for precise and uniform blends for every batch.

Called RTLS (Real Time Live Scale), the technology relies on progressively shorter opening times of the dosing valves to deliver precise blends.

Through continuous compensation of the different flow characteristics of the plastic pellets, with adaptive software algorithms, a single standard and precise valves can be employed for virgin materials, regrind and powder.

Wittmann’s blenders are available for material throughputs from 130 to 5,000 kg/h (285 to 11,000 lbs./h).

Robot for three-plate mold applications

Targeted at pick-and-place applications where the speed and precision of three-axis brushless servo operation may have seemed uneconomical in the past, the new Axess Twin Series from Sepro America are priced competitively to other servo robots in comparable sizes.

Designed for three-plate mold applications, the Axess Twin has two vertical-axis arms on a single horizontal beam, and can be applied to all three Axess models: the Axess 10 for molding machines up to 300 tons; the Axess 20 for machines as large as 400 tons; and the Axess 30 for machines as large as 600 tons.

The unit’s “Y-free” function provides for the programmed release of the strip-axis motor, allowing free movement of the robot arm and load-free ejector tracking. A pneumatic secondary wrist rotation (R2) can be added, and an elastic gripper mount is an option on Axess Twin sizes 20 and 30.

The Axess-Touch electronic control system uses 32-bit microprocessors and an icon-driven touch-screen user interface, and offers the same kind of pick-and-place and EPS programming options as the Generation IV Visual controls.

Wheel dryer dries resin and regenerates desiccant in one operation

The new NovaWheel system from Novatec is a rotating wheel dryer that continuously puts dry desiccant into service while regenerating saturated desiccant in the same rotational cycle provides resin processors with a simple, compact and low-cost alternative to conventional twin-tower dryers.

The NovaWheel dryer also exhibits less variation in dew point than other wheel dryers because models of all sizes use a steel link drive chain instead of a belt to drive the desiccant wheel.

The new dryers are particularly effective with heat-sensitive resins such as polyethylene terephthalate (PET) and PET modified with CHDM (PETG), and are available for 45 to 2,270 kg/hr.

Energy-efficient drying system

Processors who run large quantities of any material that requires high-temperature drying — above 121 Celsius — can reduce energy consumption by up to two-thirds with the new EnergySmart polymer drying system from Conair.

Recycling hot, dry air to raise the temperature of the new resin entering the drying hopper, the new system has been shown to be far more efficient than conventional desiccant dryers when drying PET and other materials that require high-temperature drying for extended periods.

The EnergySmart dryer is a “two-stage” system, incorporating a hot-air circuit and a dehumidified-air circuit. In the hot-air circuit, some of the return air exiting the top of the drying hopper is channeled through the filter and then reheated before being re-introduced to the drying hopper. Conair’s system saves energy by not removing heat in the return air heat exchanger, and by not having to add as much to the air for its next trip through the hopper. The dehumidified circuit is comprised of a standard, although smaller, Carousel Plus dryer.

The Conair Drying Monitor helps provide precise control, and temperature readings from the monitor are also used to adjust and fine tune the volume of air in both air circuits.

Other efficiency-enhancing features include gas heat, a unique hopper air distribution design, insulation to prevent unnecessary heat loss, and Carousel Plus Technology.

Hydraulic, electric drive shredding machines

Weima’s hydraulic drive single shaft shredders are designed for tough and difficult to shred plastics, as well as films and mixed materials.

Speed and torque can be adapted according to the material to be shredded, without undesirable current peaks arising. Also, the available power drive can be optimally applied so that the power consumption under partial load can be reduced by as much as 30 per cent.

On units with compact drive, the electric drive motor is connected directly with the shredding machine and adjusted via a frequency converter to the required speed and torque, so that it is possible to desist from use of a gear.

The machines are characterized by a compact design, high performance, in particular with the single shaft shredders in the speed range of 20-200 rpm.

INJECTION MOLDING

Engel to highlight machine innovations

Austrian injection molding machine manufacturer Engel will show the newly developed, compact, fully electric e-max machine (pictured) with a clamping force of 1,000 at K this year.

The e-max offers a new clamping unit with tie-bars, a large opening stroke, and generously dimensioned mold fitting space. The injection unit achieves high injection speeds, high pressures, excellent precision, excellent dynamics and best-of-the-breed performance.

The company will also show two new machine sizes for its speed range, high-speed machines for injection molding of packaging. The new machines are the speed 380 and speed 500 types, with 3,800 and 5,000 kN clamping force respectively.

According to Engel, these machines offer the shortest dry cycle of any packaging molding machine on the market.

The newly developed five-point dual-toggle lever offers excellent motion dynamics and smooth acceleration and braking characteristics. Active Speed Setup guarantees smooth running despite fast movements.

After setting the opening stroke and speed, the machine sets all remaining parameters autonomously. The moving mold mounting platen is not mounted on tie-bars but on a moving carriage on the machine frame. Screw advance speeds of up to 1.000 mm/s guarantee precise and reproducible filling of molded parts with extremely thin walls.

Additionally, the new IL 3560 inline injection unit can also be equipped with barrier screws for stress-reduced material plastification despite high output levels.

EXTRUSION


Single-screw concept for direct PET processing

Battenfeld is presenting a new, economical single-screw extruder concept for the production of premium-quality A-PET sheet.

The new process variant developed by Battenfeld is suitable for processors operating single-strand extrusion lines with an output between 800 and 1,000 kg/hour, and wishing to remain flexible by being able to process not only PET, but also polystyrene (PS) or polypropylene (PP).

The novelty is the combination of a single screw with a modified planetary section for highly effective melt degassing. Although the capital investment is comparable to a single-screw extruder with a conventional pre-drying unit, the maintenance and energy costs of the new concepts are considerably lower.

The first extruder of this type has been running at a European manufacturer of PET thermoforming sheet, showing excellent in-production performance. With this equipment, both virgin A-PET and purified reclaim bottle flakes with maximum initial moisture content of 3,000 ppm can be processed.

Motorized dual deckle for extrusion coating

A motorized dual deckle with a spring-loaded external segment from Extrusion Dies enables extrusion coating processors to automate width changes, increase the precision of deckle settings, reduce or eliminate manual adjustment, and cut downtime between job changes.

An AC motor drives the external deckle and the primary internal deckle as a single unit, while a smaller motor drives a secondary internal deckle that fine tunes the flow at either end of the die, minimizing the formation of edge bead. Besides reducing the time needed to change width settings, motorization makes it possible to run the deckle as part of a computerized processing system.

Also, with standard external deckles, operators need to loosen and tighten fasteners for every change in product width. Extrusion Dies has replaced this system with a spring-loaded device that provides constant pressure at the lips of the die while permitting width changes with little to no manual adjustment.

Because the deckles are linked to the same drive, they function as one system. In addition, they substantially reduce polymer leakage from the die.

COMPOUNDING

Kneader for high-grade cable compounds

The new high-performance MX Kneader by Buss AG is a further development of the universal Buss MKS Kneader, optimized for high grade polyolefin-based cable compound processing and special masterbatch production.

The throughput is 2.5 times more without any size increase, and specific power consumption for compounding is 15 per cent lower. Also, halogen-free flame-retardant cable compound quality is better than ever, with very high fillers content up to 68 per cent by weight.

The technological advance is mainly due to the new four-flight screw and redesigned kneading chamber with greater volume. As in all Buss Kneaders, the screw oscillates axially each time it rotates.

The mass temperature rise as a function of screw speed is significantly less than before, enabling screw speeds up to 800 rpm without exceeding the maximum admissible temperature of 190 Celsius for cable compounds.

Buss has innovated its MX Kneader drive, with a compact combination of four water-cooled induction motors actuating the screw shaft through epicyclical and linear gearing. After compounding, the product is taken over by a rugged flanged-on extruder screw, specially designed to build up the necessary pressure for melt filtration and product granulation.

The MX Kneaders also comply with strict noise protection norms, and the PC control interface with visualization ensures intuitive operator guidance.

Compounding system offers increased throughput

The new ZSK Megavolume Plus high-performance compounding system from Coperion provides increased throughput, a wider operating window and superior flexibility.

With a torque of 11.3 Nm/cm3, the ZSK Megavolume Plus makes it possible to compound feed-limited products with high energy consumption at high throughput rates. Since the mean shear rate during compounding is reduced by the large flight depth and the high filling level, the screw speed can be increased without negative effects.

Typical applications of the compounding system include rigid PVC and plasticized PVC compounding; and compounding of halogen-free, flame-retardant cable compounds based on polyolefins, as well as other filled compounds.
