Weima improves rotor for better shredding
Weima Maschinenbau GmbH has further developed the rotor of its single-shaft WLK-type shredder, especially for shredding textile filaments, tapes and films.
The F-rotor has a novel blade separation and cutting geometry for optimal shredding with a high level of energy efficiency.
When shredding films and filaments, those materials tend to wrap themselves around single-shaft rotors. On the F-Rotor, the full extent of the rotor engages with the stator blade, quickly shredding the material. A much narrower gap than earlier rotor versions guarantees controlled feeding of the material to be shredded, according to Weima, of Ilsfeld, Germany.
The firm's U.S. operation, Weima America Inc., is in Fort Mill, S.C.

Autodesk previews digital prototyping
Autodesk Inc., which bought Moldflow Corp. in May, has developed a feature that allows plastics designers and engineers to automatically create thin-walled plastic parts and features such as grills, rests, bosses, snaps, lips, grooves and fillets.
Autodesk Investor Plastic Features Technology Preview is available on its Autodesk Labs Web site.
The company in San Rafael, Calif., said it combines Autodesk's industrial design products with Moldflow injection molding simulation software and mechanical design simulation software from PlassoTech Inc. of Calabasas, Calif., which Autodesk acquired last year.
``Plastics are one of the fastest-growing engineering materials, and Autodesk is committed to providing customers with scalable, attainable and cost-effective digital prototyping solutions that help take their design productivity and innovation to new heights,'' said Robert Kross, senior vice president of Autodesk Manufacturing Solutions. ``We encourage anyone involved in plastic design not just current Inventor [software] users to try Inventor Plastic Features.''
For a limited time, the preview is available for free. For information, visit http://labs.autodesk.com.
Pump-control system reduces energy use
Kadant AES, a division of Kadant Inc., said its Unigy PhD pump-control technology is designed for hydraulic drives on plastic injection molding machines.
The patented technology reduces energy consumption while improving system monitoring and diagnostics for new and retrofit applications, according to the company in Queensbury, N.Y.
It uses intelligent pump-control software to produce precise flow rates and pressures, by continually sensing demand, managing pump speed and applied torque as needed.
Unigy PhD takes advantage of pump-modeling software in closed-loop flux vector drives for hydraulic power generation.

Promex can measure profiles in seconds
Ascona GmbH of Meckenbeuren, Germany, reports that Greiner Extrusionstechnik GmbH the Austrian maker of dies and vacuum calibration systems used to make vinyl windows uses an Ascona measuring system.
Greiner uses Ascona's Promex measuring system to check profiles. In the past, Greiner technicians placed test samples on a light source, to get an enlarged picture on a projection area. Then technical drawings on parchment paper were placed on top of the picture for comparison. Measurement of each profile took about an hour.
Promex uses a scanner to measure the profile in just seconds. The data is centrally stored, and can be examined or edited by the eight engineers that work in the test department.
Also, Greiner now can exchange data with customers, including information on when the die will be completed.

MicroDos offers quick,cheap color changes
KraussMaffei AG said its MicroDos color-metering system for polyurethane processing is a cost-effective solution for frequent color changes.
To eliminate the risk of colors carrying over, all elements that come into contact with the pigment are integrated into the color-change module. For a color change, the whole module is swapped for a new color module. The line is back in production in minutes, said the Munich, Germany-based company.
MicroDos also can be used to dispense other PU additives, such as blowing agents, catalysts and stabilizers.
The company's U.S. operation is in Florence, Ky.

IMS coating protects metal mold surfaces
IMS Co. of Chagrin Falls, Ohio, is offering Night Coat Rust Preventive and Acid Neutralizer that quickly wets out across the mold and displaces moisture, neutralizes acid and protects polished metal surfaces.
It is easily removed with startup shots in injection molding, or by using standard solvents.
IMS said a neutralizer is important when molding PVC or chlorinated PVC in which out-gassed hydrochloric gas can combine with moisture to create corrosive hydrochloric acid.

PCS Co. distributing NanoPlas coating
PCS Co., a supplier of mold bases, components and hot runners, is the exclusive North American distributor of NanoMoldCoating, after PCS signed an agreement with Don Kirchner, president of NanoPlas Inc. of Elk Grove Village, Ill.
NanoMoldCoating is a semi-permanent, self-applied coating designed to reduce cycle times, rejected parts and maintenance, while improving part quality in injection molding, blow molding and rubber molding.
The coating creates a nanoscale barrier from nano-formulated molecules. The nonmigrating coating can withstand temperatures up to 1,000º F.
PCS of Fraser, Mich., claims NanoMoldCoating can eliminate the need for traditional mold release products.
