Close-Up on Technology

New Concept for Multi-Shot Molds
Production of multi-color or multi-material articles on a conventional injection press without additional equipment is enabled by new tooling technology from German moldmaker Zahoransky Formenbau GmbH.

Starting Up

Your Business in Brief - October 2009
Reifenhauser Buys KiefelReifenhauser GmbH has acquired the blown film extrusion equipment business of Kiefel Extrusion GmbH from Bruckner Technology Holding GmbH.

Your Business Pricing Update - October 2009
Moderating feedstock costs, slack domestic demand, and slumping exports are putting the brakes on price hikes for most commodity resins.


Getting Down to the Nitty-Gritty
Last month in this space I outlined in broad terms the changes we planned for Plastics Technology beginning in November.

Materials Handling: New Equipment Emphasizes Efficiency & Value
Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.

Testing & Measuring Instruments: More Versatile, Compact, Affordable
From polymer characterization to on-line bottle or preform inspection, coordinate measuring, and color sensing, new testing and measuring instruments at the NPE show in Chicago were easier to use and more compact, yet often packed higher performance than earlier versions—and sometimes with a more attractive price tag.

Keeping Up With Technology

Downstream Tubing Line for Medical Applications
A new compact cooling tank and puller/cutter combination engineered specifically for tight-tolerance medical tubing was displayed at the NPE show in Chicago by CDS Inc., Lachine, Que.

Durable Non-Return Valve
A new three-piece, ring-type check valve for general injection molding applications comes from Zeiger Industries, Canton, Ohio.

Enhanced Film Sensor Has Wider Measurement Range
The upgraded FG710S Infrared Film Thickness Gauge from NDC Infrared Engineering, Irwindale, Calif., is designed for high-precision measurement of basis weight or thickness of single- or multi-layer films with capabilities the supplier says were previously unavailable in any on-line sensor.

Expandable Cavities Now Standard
A standard line of expandable cavities is offered for the first time by Progressive Components, Wauconda, Ill.

Faster Position Sensors for High-Speed Molding
WEB EXCLUSIVE: Injection molding, thermoforming, and other machines that require high-speed position sensing can benefit from a new faster update option for magnetostrictive Temposonics linear position sensors from MTS Systems Corp.’s Sensors Div., Cary, N.C.

Highly Heat-Conductive Carbon Fiber on the Way
Teijin Ltd. of Japan is developing a new carbon-fiber filler that conducts heat better than silver or copper.

Infrared Barrel Heating Now for Smaller Presses
Energy-saving TCS Infrared barrel-heating technology from the ServTek group of Milacron Inc., Batavia, Ohio, is now available for presses under 400 tons.

Large Pipe Tooling Improves Material Flow
A combined die and reservoir system in the new Model 2030 tooling system from Guill Tool, W.

Line of Extruders Debut for Pipe, Profiles & More
The Max Extruder series from R&B Plastics Machinery, Saline, Mich., comes in sizes from 1 to 10 in. diam. in all L/D ratios and with PLC, PC-based, or discrete control systems.

Long-Fiber PP for Auto Interiors
Three new long-glass PP compounds have been customized for auto interior parts as alternatives to SMA and PC/ABS.

Lubricant Packages Certified by NSF & PPI
Honeywell Specialty Materials, Morristown, N.J., reports that its Rheochem line of high-performance lubricants (HPLs) have been certified by NSF International and the Plastics Pipe Institute for use in PVC water pipe.

More Ways to Use Unique Coinjection Technology
Spirex Corp., Youngstown, Ohio, is broadening the application range of Twinshot technology, which uses a special screw and barrel to convert a standard single-barrel injection press for coinjection.

New Blown Film Coolers
The BFC Series of blown-film coolers from Mokon, Buffalo, promises to boost film output, particularly in warmer climates or other regions where ambient air temperature rises during the summer.

New HDPE Bottle Resins Boost ESCR & Stiffness
Two experimental HDPE blow molding grades from Dow Chemical Co.’s Basic Plastics unit in Houston are said to offer dramatic increases in ESCR, higher stiffness, and significant processing advantages over existing unimodal and bimodal resins for bottles and large parts.

New Polyamide-imides with Added Wear Resistance
WEB EXCLUSIVE: Solvay Advanced Polymers, LLC, Alpharetta, Ga., has a pair of new injection moldable Torlon polyamide-imide (PAI) compounds said to provide significantly better wear resistance than previous grades.

New Polycarbonates for FR, Medical & LED Uses
WEB EXCLUSIVE: Three new specialized grades of polycarbonate have been developed by Bayer MaterialScience LLC, Pittsburgh.

New PVC Impact Modifiers and Heat Stabilizers
WEB EXCLUSIVE: “A profound step change in providing higher impact resistance in combination with high gloss” is how Dow Chemical Co. describes its new Paraloid KM-X100 impact modifier for PVC window profiles.

PET Bottle Output Rises, Energy Consumption Falls
WEB EXCLUSIVE: At last month’s Drinktec exhibition in Munich, Germany, Sidel of France introduced new technologies and services to produce more PET bottles faster with less energy consumption.

Plastic Baffles for Turbulent Cooling
Superior mold cooling and shorter cycle times are said to be possible with a new mold baffle design from D-M-E Co., Madison Heights, Mich., that improves turbulent flow in the mold cooling channels.

Side-Entry Robot Is Fast, Light, Clean-Room Ready
A new side-entry robot designed for production of pipette tips and other medical disposables will be shown at at this month’s Fakuma show in Germany by Hekuma GmbH of Eching.
