Tobin Manufacturing was established in 1974 by John Tobin's father Jack Tobin as a manufacturer of a two component positive displacement meter/mix/dispense machines to dispense polyurethane elastomers into molds for high volume production. Jack relied on his formal training as a chemical engineer, combined with over 20 years designing and selling multi-component meter-mix equipment, to satisfy the need for reliable and accurate metering machines for the urethane industry. He understood established mixing principles wherein blade and baffle designs maximize turbulent mixing and incorporated those principles in his mixer designs. The Dub-l-Bar machine was the equipment of choice by the majority of manufacturers in the rapidly expanding skate board wheel industry. Typical production runs of 10,000 to 12,000 parts each day were common.

Over the years the equipment gained a reputation for its metering accuracy, versatility and simplicity. Applications expanded to castor wheels, fuel tank liners, automotive body styling kit components, foam and elastomer filter gaskets, rotationally molded mannequins and myriad other parts. The machine was found especially versatile for molding prototype parts due to the ability to economically process small quantities of product and switch from system-to-system quickly. The key design feature assuring metering accuracy was the ability of both metering cylinders to move proportionally at the same rate regardless of ratio changes.

The equipment is especially suited for processing urethane elastomers filled with various fillers, including calcium carbonate, barium sulfate, aluminum tri-hydrate, micro-balloons, and other abrasive fillers. Because there is no metal-to-metal contact in our unique metering cylinders, the wear experienced in other types of cylinders and gear or progressive cavity pumps is absent.

Today, John Tobin continues the creative tradition of his father, Jack, and manages production, product development and field technical support for the entire line of Tobin Manufacturing products.
