TRI-MACK Plastics Manufacturing Corporation

For more than 30 years, Tri-Mack Plastics Manufacturing Corporation has been at the forefront of high-performance thermoplastics manufacturing.  Originally established in 1974 to manufacture aircraft engine friction-wear plastic parts, the company has grown to become the industry’s authority in identifying the best material, part design and manufacturing process for the job.  Tri-Mack’s extensive materials knowledge begins with Edward J. Mack, the company’s founder and a pioneer in polymer chemistry and tribology (material friction, wear and toughness).  This material expertise allows Tri-Mack to participate in a program from initial concept to commercial production.  We pride ourselves on our engineering support, which includes material selection, part design assistance, and process development.
