Tro Manufacturing Company

Tro Manufacturing Company, Incorporated was founded in 1964, and will celebrate it's 46th anniversary in June 2010.

Tro was founded by Laddie A. Sanda Sr. as a Tool and Die Shop. A contract to produce Ogives for The United States Military turned our focus from machining to stamping.

From this beginning over 3 decades ago, Tro has grown into an industry leader in progressive, deep draw, and transfer press technology. With cutting edge technology in the form of 3-axis computer controlled servo-motor transfer presses up to 1000 tons, Tro has enabled its' customers to realize cost and quality gains never before possible in the industry.

Tro's philosophy of "Do It Right The First Time", coupled with a total commitment to quality is demonstrated in every phase of our operation.

Tro is certified to ISO TS 16949.  We are a Preferred stamping supplier to Robert Bosch Corporation, and are a Strategic Preferred Supplier to Continental Teves.

Our major customers also include: Diemolding Corporation, Aisin, Advics, and Hilex N.A. Additionally, we are producing and supplying all the major components to TRW for the only all aluminum Hydraulic Brake Booster made in NAFTA.


Tro also has an extensive Engineering capability, with three full time Engineers, all of whom come from a tooling and manufacturing background. Our Engineering department is expert at "value engineering" or "engineering cost reductions". Due to our advanced engineering, design and manufacturing capabilities out customers have been able to realize consistent cost reductions and quality improvements.

Tro's structure and size allow Production, Quality Control, Shipping, Engineering and Management to work closely together to ensure continuity of production and development. Problems, Customer requests, data, etc. do not float around in some bureaucratic "hold file", instead, they are addressed immediately.

Tro's major market is automotive related, but we do work for the marine, electronics, railroad and appliance markets as well. Our customers include: American, German, Japanese, Mexican and Brazilian automotive tier 1, 2 and 3 suppliers, Marine OE and tier 1, and appliance/vending OE's.
