TOBIN MANUFACTURING, LLC designs and manufactures meter, mix and dispense machines using positive displacement piston rod metering pumps feeding dynamic, static or impingement mixers for processing temperature controlled or hot cast urethane elastomers, urethane foams or epoxies.  Tobin also provides spare parts, helix mixers, mix heads and service for DECKER foam machines.
ABOUT US

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, LLC products.


Sales and Marketing of Tobin equipment is handled by John’s partner Bill Shaw who has over 35 years experience in urethane processing. Bill was a partner in Decker Industries, Inc. in Palm City, Florida serving as Sales and Marketing Director from 1981 until 1998 when the company was sold. He continued selling the firm’s low and high pressure urethane processing machines until Decker was again sold and relocated to Ohio.
Christopher Shaw recently joined Tobin Manufacturing and is responsible for customer relations, production scheduling and inventory control. Christopher’s 10 years experience working in different departments of Decker Industries greatly adds to our core capabilities.

The Tobin equipment line has evolved to include a variety of machine configurations for specific application niches while staying true to the original design principles and simplicity that makes the equipment successful and even more relevant today.

Recent additions to the product line include:

•    RotoKam Model 2F, fixed ratio, electric/cam drive metering unit with dynamic mixing
