Wittmann touting sprue-picker robot
A hand-held pendant runs the W601 sprue-picker robot from Wittmann Robot & Automation Systems Inc. of Torrington, Conn.
A cable track supports air and electrical lines on the robot, eliminating air-hose fatigue. Linear bearings and rails provide smooth operation.
Mold setups can be stored in the controller.

Vulcan introduces water-removal unit
Vulcan Machinery Corp., an extrusion downstream equipment maker in Akron, Ohio, has introduced a machine to strip water from profiles or strands during compounding.
A remote air knife, positioned at the end of the water-cooling tank, shoots high-velocity air from a regenerative blower. The process water is removed and returned to the cooling tank. Then, the vacuum generated at the blower intake is applied to remove the residual moisture.
Vulcan said the method is 40-50 percent more efficient than using a positive-pressure air knife alone.
Prices for the water-removal unit, Model WRU14, begin at about $14,000.
Vulcan also has introduced a machine that coils strapping tape. Features include a motor-driven coiling spindle, set up in a tension mode and fully programmable alternating-current servo-driven traverser axis.
A modular design lets Vulcan provide multiple spindle arrangements.

Allen-Bradley unveils temp-control module
Allen-Bradley Co. Inc., a unit of Rockwell Automation, has introduced a barrel temperature-control module, the 1746-BTM, for injection molding, extrusion and blow molding.
The four-channel temperature barrel includes automatic tuning. It integrates barrel temperature control into Allen-Bradley's SLC 500 controllers. The 1746-BTM executes temperature controls within the module, independent of the SLC controller. That helps free machine builders and systems integrators from writing and debugging complex temperature-control strategies using relay ladder logic. List price for the 1746-BTM is $1,200.

Imtech develops viewer for CAD files
British firm Imtech Design has developed 3D View, a computer-aided-design file viewer that it says is inexpensive but powerful.
Imtech's research said that only 15 percent of those who use CAD systems actually create or modify designs, while 85 percent just view the CAD files. 3D View measures overall size and specific dimensions, and calculates part volumes and surface areas.
3D View consists of modules. The main core viewer, priced at about $160, can import universal file formats. Separate direct interface modules are available, including a Native Catia module for $415 and a SolidWorks direct interface for $83.
Imtech of Chislehurst, England, offers a free trial version. Users with computers running Windows 95, 98 or NT 4.0, can download the software from Imtech Design's Web site, www.imtech design.com/3dview.

Dynisco companies introduce equipment
Two Dynisco Inc. units debuted products at Antec '99, held May 2-6 in New York, including a new controller, a rheometer and a pressure transducer.
Dynisco Instruments said its DPC535 process and pressure controller is self-tuning, controls eight points along the process, and can accept input from sensors measuring variables like pressure, temperature, level and flow.
Dynisco also showed its new MRT Series of pressure transducers. Special electronics are designed to select four of the most commonly used pressure ranges: 3,000, 5,000, 7,500, and 10,000 pounds per square inch. To change the pressure, the operator simply uses a screwdriver to turn a seal screw.
Another unit, Dynisco Polymer Test, claims its in-line melt viscosity sensor, the VS 1000 ViscoSensor, is the world's smallest in-line rheology instrument. It measures 17 inches long by 8 inches wide.
The firm also showed a two-barrel rheometer, the LCR7002, which allows simultaneous testing of a high and low shear rate. By placing a short length-to-diameter die in one bore and long die in the other bore, one test run can measure Bagley corrections and elongation data
