For more than 45 years, Proper Group International has developed a reputation as a “world class” manufacturer in the plastics industry. In 1996, Proper expanded its support into the Southeast region of the United States.
Initially, the facility located in Anderson, South Carolina was set up to support Proper Tooling’s expanding business with BMW, Mercedes, and other manufacturers in the Southeast. In 2002, Proper expanded it’s line of service to include production injection molding. This was the beginning of Proper Polymers. Over the years, we continued to leverage the innovation and problem solving capabilities that Proper Group International has become known for. Our customers, who have recognized us as a “turn key” production injection molding operation, facilitated the rapid expansion into the Southeast. The full service production facility has grown to over 71,000 square feet, and houses 21 injection molding machines ranging from 77 Ton to 1500 Ton.
