Rosbro Plastics Co., a family-owned blow molding company founded in 1946, will close down June 27, a top official said.
Rosbro will close its Pawtucket, R.I., factory and sell the equipment — 12 extrusion blow molding machines and two injection presses — according to Harris Rosen, president of E. Rosen Co., which owns Rosbro.
Rosbro employs 53, molding jars and bottles mainly for the health and beauty industry. Some of the machines are set up for wide-mouth finishing in the machine, Rosen said in a June 5 telephone interview from Pawtucket.
Rosen said the business had become unprofitable, despite efforts by management and the plant's union, United Steelworkers of America Local 4652.
When the company was founded after World War II, it did injection molding. Rosbro got into blow molding later, when that technology was introduced, he said.
Rosbro followed the federal plant closing law and notified the union in advance of the closing. Union officials could not be reached for comment.
Rosen said the company plans to sell all the machinery. He said the blow molding machines include Hayssen Monoblows and Autoblows, and Fischer VK1-5s. He did not know the brands of the two injection molding presses.
He said Joseph Danowski, Rosbro's vice president and general manager, is handling the machine sale.
Rosbro Plastics Co. and E. Rosen Co. are both in the same building in Pawtucket.
