IRWINDALE, CALIF. (Aug. 30, 11 a.m. EDT) — Noncontact sensor maker NDC Infrared Engineering Inc. has introduced an infrared gauge and an X-ray transmission gauge for measuring film during production. The Irwindale-based company will show the products at K 2004 in Dusseldorf, Germany, this fall.
NDC also announced that a customer in China has purchased what NDC believes is the largest scanner ever built for a biaxially oriented polypropylene film line, measuring 37½ inches wide.
In the K show offerings, the FG710 infrared gauge performs on-line measurement of weight and thickness for single-layer and multilayer films. Featuring NDC's high-resolution IR filters incorporated into a robust head, the sensor continuously measures as many as four product ingredients at the same time, making the unit ideal for coextruded films, according to NDC.
The gauge can measure film thicknesses from 0.5-200 mils.
The Model 312 X-ray transmission gauge measures streak resolution on film. Features include a small spot size and high-energy flux. The gauge also has a digitally tunable, high-voltage power supply.
Also new from NDC is the MiniTrak family of scanners, which the firm said are versatile, small and easy to use. The cross-web beam measures 8 inches by 8 inches in a U-beam design. The outer shell houses virtually all of the mechanical and electrical components.
The big scanner is going to Hefei Guofeng Plastics Group of China. It marks the 45th biax system NDC has installed in China, according to Edward Dong, NDC's vice president and general manager of China operations. The scanner is the second purchased by Hefei Guofeng, which also bought one in 1997.
The AccuTrak open-ended “C” scanner will measure films up to 34 feet wide. It will be installed on a BOPP line made by Bruckner Maschinenbau GmbH of Siegsdorf, Germany.
The BOPP film made by Hefei Guofeng is used in food and cigarette packaging, and lamination-grade films. NDC employs 22 people in four offices in China, in Shanghai, Guangzhou, Beijing and Kunming. NDC President Bromley Beadle said the company sold its first system in China in 1974.
