ANN ARBOR, Mich. (Dec. 4)—SaarGummi Americas has opened a 35,000-sq.-ft. automotive glass encapsulation plant in Guadalajara, Mexico. The plant, SaarGummi´s first in Mexico, is dedicated for now to supplying the removable, encapsulated glass panels for General Motors Corp.´s Chevy Avalanche sport utility vehicle, which is being assembled at a GM plant in nearby Silao, Mexico, SaarGummi said. In its current format, the plant can put out 200,000 window units a year, but has reserve capacity that would allow production to double, according to Markus Werner, president and chief operating officer of Ann Arbor-based SaarGummi Americas. Production capacity already is more than 50 percent greater that originally planned, Werner said. SaarGummi Americas is a subsidiary of Saar-Gummiwerk GmbH of Wadern-Buschfeld, Germany. It expanded its operations in the Americas considerably in July when it bought the design, engineering and manufacturing operations in the U.S. and Canada of Thona Corp.
