OSTER Manufacturing Company 1997 - Present

In 1997 Superior Threading Inc. purchased the Oster Manufacturing Company from Landis Threading Systems a division of the then Allegheny /Teledyne Corporation. All fixtures, Blueprints and Patterns were moved to Owosso, Michigan. The current owner is a former Oster employee and has been affiliated with the Oster Manufacturing Company since 1983.

Starting with nothing but a small facility, existing inventory, and a few machines; the first ten years after purchase were spent laying the groundwork for where we are today. Initially only offering replacement parts and tooling for existing machines we have made continuing investment to expand our manufacturing footprint and improve the Oster product.

In 1998 we started the Oster Complete Rebuild program, taking used Oster machines and bringing them back to life to match the quality of a new machine. With this we were able to keep the old machines in service as well as produce all replacement parts and tooling.

In 2000 we moved into our current 15,000 sq ft facility which allowed us to expand our manufacturing capability. In 2006 the recovered Oster Manufacturing Company purchased our first CNC machine for manufacturing parts. Since then we have acquired over $1,000,000 of CNC equipment to usher Oster threading machines into the modern era of manufacturing.

In 2009 with many years of rebuilding machines and their replacement parts under our belt we had the expertise, confidence and equipment to begin building new machinery again. Starting with the production of the Oster 700 series and our flagship threading machine the 792ALX we built the first new Oster threading machine to be produced in over 15 years. We are currently the only American manufacturer to offer new heavy duty pipe and bolt threading machines that are designed for the factory environment to be run day in and day out without failure.

Oster parts and products are the only items we manufacture and we pride ourselves in honoring the spirit of high quality manufacturing based on pride in good work espoused by Herman W. Oster himself.
