Sajar Plastics was founded in Middlefield, Ohio in 1949 with three plastic injection molding machines producing straight injection molded parts. “Sajar” is an acronym reflecting the last names of the founding three owners of the company. Sajar grew steadily over the years expanding manufacturing capabilities and facility to over 150,000 sq. ft., a direct result of earning a reputation in the custom molding industry as an innovative molder supplying high quality large plastic parts with complex designs and high cosmetic requirements at competitive prices. In the early 1980’s Sajar was one of the three original companies which developed gas assisted injection molding and continues to pioneer its use and application today. Since then Sajar has acquired the equipment and processing technology necessary for the production of large complexly designed parts and the quality culture required to produce consistent high quality cosmetics on customer facing components. To date Sajar has commercialized over 500 gas assisted parts for leading OEMs in a wide variety of industries including medical, laboratory and diagnostic, manufacturing, business, and retail registers/dispensing machines. With small, medium, and large tonnage presses, along with in-house painting and full secondary operations and assembly, Sajar is well equipped to consolidate your supplier base by acting as a one stop shop for large projects requiring a wide variety or plastic part sizes and finishing specifications.
