Twinco was started by John H. Schatz in the basement of his house for the purpose of making tools and dies for various industries. The company was incorporated in 1965 as Twinco Manufacturing Company Inc.

Until 1984 Transcontrol Corporation was Twinco's largest customer. Transcontrol produced vital relays and signal systems for the Railroad and Transit Industry. During this time Twinco's capabilities grew to a point where we manufactured almost all the components Transcontrol required to assemble a product.

Twinco has grown over the years because of our commitment to the customer. We continually invest in the best and most modern, facilities and equipment to enable our employees to be as productive as possible.

Twinco is primarily engaged in production of electrical and electro-mechanical products for the Railroad & Transit Industry. In 1985 Twinco received approval of its first major product: a Train Stop for the New York City Transit Authority. As we have grown so has our products.
