NFM to introduce twin-screw extruder
NFM/Welding Engineers Inc. will introduce its TEM Series 26-millimeter twin-screw extruder for laboratory trials or small production runs at the Society of Plastics Engineers' Antec conference, May 6-10, in Cincinnati.
Massillon, Ohio-based NFM can outfit the extruder with casters so it can be moved around easily. Typical applications include engineered plastics, fiber and filler compounding, color concentrates, polymer alloys, direct extrusion and reactive extrusion.
NFM will exhibit at booth 623 during the show.

KM builds extruders using flow assembly
Munich, Germany-based Krauss-Maffei Kunststofftechnik GmbH has invested in a flow assembly-line production for its extruders, dubbed synchronized flow assembly.
The move follows Krauss-Maffei's earlier flow assembly for its MX and CX injection molding machines.
K-M is now using synchronized flow production to build all electrical and mechanical subassemblies for twin-screw extruders from the KMD 75 to the KMD 114, and single-screw extruders from KME 45 to KME 90. The machines are now built in four synchronized stages.
The firm renovated its extruder production late last year. Production is now fully synchronized, and parts are ``pulled'' by the requirements of the assembly line.
``It is not only our products that must be continuously improved, but also our processes,'' said Josef Mrtl, Krauss-Maffei's chief executive officer.

TyPhoon nozzle aids homogenous blend
Plasti-Co Equipment Co. of Brighton, Mich., and StaMixCo LLC of Brooklyn, N.Y., have developed the TyPhoon static mixing nozzle assembly that turns the melt over 256 times during injection, ensuring a homogenous blend.
The mixing action takes place with very little back pressure.
Sizes of the nozzle assembly can handle screw diameters of 18-180 millimeters.
The TyPhoon does not impede screw recovery time and costs less than mixing screws, with a shorter lead time, the firm said. It also can be moved between machines. The unit is sold complete with heaters, thermocouples and a nozzle tip, ready for installation into the injection press.
Plasti-Co is a division of AIC Equipment & Controls Inc., a Brighton machinery sales representative firm, distributor and screw and barrel maker.

IMS high-speed Hydra controls mold temps
IMS Co.'s Hydra pressured mold temperature controller uses direct heating and cooling to ensure fast response and tight control.
The high-speed pressurized system circulates water through the mold. IMS, based in Chagrin Falls, Ohio, said pressurizing the water allows temperatures up to 250° F.

Herbold granulators used for PET bottles
Herbold Meckesheim GmbH said the newly developed SB granulators are used for recycling PET bottles and as secondary granulators where shredders cannot reach the required granulator size.
The high capacity comes from a forced-feeding device that gives a higher packing density in the grinding chamber, so the material cannot ``dance'' on the rotor and escape the cutting tools.
Herbold is based in Meckesheim, Germany.

EOS Formiga features new, smaller design
EOS GmbH Electro Optical Systems of Krailling, Germany, rolled out its new generation of plastic laser sintering systems for rapid prototyping May 1 at Rapid 2007 in Detroit.
Formiga P 100 is a cost-effective, flexible entry into laser sintering and not a scaled-down version of the firm's EOSINT P-Class machines, said Jim Fendrick, vice president of EOS of North America Inc. in Novi, Mich.
``It is an entirely new design,'' Fendrick said.
The Formiga is smaller and lower priced, he said. It has 23 components made by laser sintering, such as the hopper, switch cover and pyrometer elements - proving the process also can be used for manufacturing, not just rapid prototyping, the firm said.
The Formiga P 100 offers a build envelope of 8 inches by 10 inches by 13 inches.

Priamus plant offers Paulson course work
Priamus System Technologies LLC in is now offering Paulson School of Molding courses at the Priamus plant in Brunswick, Ohio.
The first course, ProMolder 1, was held in April. Certified ProMolder graduates can continue more in-depth training through Priamus, continuing with Precision PVT Processing, which focuses on using in-mold rheology for process control.
In product news, the Priamus monitor is now designed for use with rotary-table molds. The monitoring of the single mold halves is controlled by digital input signals. Sensors can be installed in half halves or in one half only, so only sensors that are actually involved in the mold process are monitored.
Paulson is in Chester, Conn.

Helix filters target injection, extrusion
Miller-Leaman Inc. of Daytona Beach, Fla., said its Helix industrial process filters are designed to remove particles and other contaminants from cooling water used in injection molding and extrusion operations.
The filters are available with a polypropylene disc media (the Helix HD series) or a stainless-steel screen (the Helix HS series).
As dirty water enters the filter housing, a high-velocity spinning action spirals heavier particles, such as sand and sediment, away from the screen down to the base of the filter housing. These particles are then flushed from the filter through a port connection.

Delta picks plastic for cooling towers
Plastic has entered the cooling tower market.
Delta Cooling Towers Inc. of Rockaway, N.J., has developed polyethylene cooling towers as an alternative to galvanized metal towers. The plastic will not rust, chip, flake, peel or require paint or other protective coatings. Also, plastic towers cannot be damaged by excessive calcium caused by high pH.
The company said one satisfied customer is Tulip Corp., an injection molder of automotive battery cases, covers and venting systems. Tulip installed the towers at its Milwaukee plant.
Another advantage is Delta's use of direct-drive fan motors, with an impeller directly on the motor, making them more energy efficient and easier to maintain.
The line of towers comes with a 15-year warranty.
