The Putnam Plastics S.J. Chen Extrusion Lab
Extrusion is a process that is used to produce continuous or cut lengths of plastic sheet, film, fiber or profiles. Items such as window profiles, catheters, tubing, pipe and the like are all produced using the extrusion process. This extrusion laboratory, located in Ball 110, has received support from the Spirex Corporation of Youngstown, OH, the Gillette Corporation, Boston, MA, and is now sponsored by the Putnam Plastics Corporation of Dayville, CT, which specializes in micro-extrusion. The lab is named for the late Professor S.J. Chen. Professor Chen was a respected faculty member and researcher in the area of extrusion processing prior to his death in 1993. The extrusion equipment in this lab includes:
