RGL Sales and Marketing Inc.

Founded by Robert Barr in 1976. Barr was already known for his work on screw design and had a barrier screw patent granted in 1970. His background was as a development engineer working for a leading extruder manufacturer in New Jersey, Hartig division of Midland Ross, Corp.

In 1976 Barr founded Robert Barr, Inc. With a patent on a new barrier screw, the BARR 2 screw, the company began marketing and designing plasticating screws for all processes. Over the next 7 years the company developed the BARR ET screw which was released in 1983.

In 2000 Mr. Jeff Myers was hired as VP Engineering and Sales. Jeff has an extensive background of 18 years in screw design especially in injection molding applications.

Then, in 2002, the company developed and patented the VBET screw which has since proven to be a superior design to anything on the market, including the ET screw. In addition, BARR has developed a number of new types of polymer mixer sections such as the Fluxion, which has been very successful in many applications.

From the time BARR Inc was incorporated in 1976, the main focus and commitment to the plastic industry has been to maximize machine efficiency and supply the highest quality product.
