Arburg Inc. of Newington, Conn., now offers a 15-millimeter screw for molding extremely small parts. Arburg said the screw and barrel, combined with its smallest injection unit, deliver accurate, repeatable shots as small as one-tenth of an ounce.
Molders of very small parts have had problems using more conventionally sized screws. First, they might use just 10 percent or less of the full screw stroke - which makes it hard to control and repeat speed, pressure and position.
Arburg said residence time is another problem, because the material moves through the barrel so slowly it often degrades before reaching the mold.
The 15mm screw is available on the new Arburg S Series machines, with clamping forces of 17 tons or 28 tons, and also on small-tonnage presses in the company's V Series. Arburg C and M Series machines may also use the 15mm screw, but because the injection unit is larger, a bigger length-to-diameter ratio is used with those models.

Facts Inc. has introduced its TIM 3001 Total Information Manager for extrusion lines, calendering, mixing or coating.
TIM 3001 will support as many as 16 process-control systems, including display of key parameters in real time. It captures process data automatically and can be used to analyze statistical quality control and statistical process control information.
The Cuyahoga Falls, Ohio, company also introduced the FactsView Shop Floor Reporting system, used with the TIM 3001. FactsView links the office and shop floor with information such as job or work orders, production reporting, scheduling and bar code support.
Other new products include an option to the 5001 Total Profile Control System, which gauges an extruded film or sheet and the TMC 6001 Total Mixer Control and TIM 3001 Batch Total Information Manager for mixing.

Molders who buy a Boy injection molding machine can earn points toward a new computer-integrated manufacturing system under a new program from Boy Machines Inc.
Exton, Pa.-based Boy began the program earlier this year when it introduced the CIM system to link Boy machines.
Points are awarded for buying, at list price, any Boy M-series machine with Procan control. A buyer who accumulates 300 bonus points earns a CIM system, both hardware and software, capable of connecting up to eight Procan-controlled machines. Purchase price of the system is $27,000.
The CIM system can be expanded to monitor up to 32 machines.
The sales promotion ends Feb. 28, 1997. To be eligible, machines must be ordered by Dec. 31, with delivery accepted no later than March 31, 1997. If the necessary bonus points are not accumulated before the end of the promotion, customers can buy additional points, at $90 per point.
Using the CIM system, an operator can monitor an entire molding operation from a single computer. Operating procedures and screen displays are the same as those on Boy's Procan controller.
Up to 10 process parameters per machine process window can be selected for display. Operators can store setups. The system also keeps track of actual production data, and it creates graphs.
Any of Boy's M-series machines with Procan control can be linked into the CIM network.

Gunther Louda GmbH of Munich, Germany, reports it sold its first fully automatic machine to inspect color plastic cards in North America, to Plastag Corp. of Chicago.
Louda said its KIS II Card Inspection Machine is already used in Europe.
It inspects all features of plastic cards, checking for printing defects, bad registration, color variations, scratches, surface defects, hologram accuracy and other quality problems.
Cards are counted individually. A hard-copy printout is automatically made listing all cards inspected. Reasons for rejects are listed.
The Louda machine also includes an automatic handling system that takes cards all the way from punching to boxing with no human handling.

The Micro Quad Multi-Layer Container Analyzer from Mois-ture Systems of Hopkinton, Mass., uses infrared technology to measure individual layer thicknesses in plastic containers.
The device uses fiber optics at several precisely defined locations. A complete measurement is done in 30 seconds.
The analyzer can measure barrier layers in plastic bottles and cans, or do on-line measurement of coextruded films.
Moisture Systems is a division of Thermedics Detection.
