Boltaron Inc. - A SIMONA Company

The Newcomerstown, Ohio facility was founded as the Plastics Division of Sieberling Rubber Company in 1954. It became Seilon Inc. in 1964 and was subsequently purchased by The General Tire & Rubber Co. (GTR) in 1968. Through a corporate reorganization in the late 1980's, GTR was transformed into Gen Corp, and this facility became an operating unit. GenCorp retained ownership until purchased by Empire Plastics, Inc. in November 1995. On October 25, 2004 Boltaron, a management owned company acquired the Newcomerstown operations from Empire.

The following is a brief overview of our processing features:

Calendering - Raw materials in powder form are fused into a homogeneous molten mass through heat and friction shear in a mixing chamber. This molten plastic is fed into a series of heated revolving rollers that squeeze the material to a desired thickness. After leaving the rollers the material passes through a series of surface conditioning and cooling rolls from which it is wound into custom rolls or cut into specified sheet dimensions.

Extrusion - A continuous manufacturing process that involves conveying mixed plastic compound through a heated barrel by a specially disengaged spiral shaped screw. The original powder blend is converted into a molten plastic mass that exits through a die which flattens the mass into a sheet of designated width and thickness. The sheet then passes through heated embossing rolls which impart a predetermined surface finish prior to trimming to the final sheet dimension. A variety of surface finishes are available.

Press Lamination - A process of producing various thickness' of plastic sheet by using heat and pressure, over a designated period of time, to fuse several thin sheets of plastic together to form one solid sheet of material. Colors can be combined to produce a multicolor edge effect and reinforcing medium, such as wire, may be embedded between layers to tailor material for a specific application.
