BREA, CALIF. (Aug. 24, 1 p.m. ET) — M.R. Mold & Engineering Corp. of Brea, Calif., acquired a 77-ton hydraulic Arburg 370S Allrounder injection molding machine for customized sampling of liquid-silicone-rubber parts.

Customers wanted the tool maker to trial molds in vertical as well as horizontal orientations, and so M.R. Mold purchased the machine with both molding capabilities. M.R. Mold began operating the press in mid-July.

The Arburg has 15mm and 35mm cylinder assemblies, said Jürgen Giesow, regional manager in Irvine, Calif., for Arburg Inc. The machine has a 15mm diving nozzle for a cold runner system and a 0.005-inch-radius nozzle for conventional molds.

Giesow and five others provided instruction July 17-20 primarily in Orange, Calif., during a University of Wisconsin-Milwaukee course on silicone elastomers technology and fabrication. At M.R. Mold’s Brea plant, Giesow demonstrated the 370S’s capabilities for 43 attendees including three employees of M.R. Mold.

M.R. Mold employs 27 including 20 mold makers. Rent hires include a molding technician and a molding making apprentice. M.R. Mold seeks individuals for molding and project management positions.

Established in 1985 and adding injection molding capability in 2003, the firm occupies 14,000 square feet and, in addition to the Arburg, operates five other presses including a 100-ton tiebarless Engel, two 55-ton Engels, a 90-ton Boy and an all-electric 110-ton Negri Bossi. The operation is ISO 9001-compliant and working towards ISO certification.
