Thuro Metal Products has been a supplier of Precision Machined Component Parts to the Automotive Industry since 1981. The first large scale projects we undertook were for families of components used in fuel injection. By the mid 1980’s, Thuro expanded into the production of Restrictors and Connectors used in the Steering Systems designed by TRW Automotive. In the 1990’s, Thuro Metal Products became a tier one supplier to Delphi Automotive, shipping daily to facilities in the Mid-West, Southeastern United States and Mexico. The largest project undertaken for Delphi Automotive, with respect to part volume, was the multi-Year, monthly production of 800,000 Plungers used in Anti-Lock (ABS) braking Systems. With more than 30 years of experience manufacture high volume, precision components used in Fuel Injection, Steering, Braking and Transmission, as well as Automotive Hydraulics, Thuro Metal Products has become a specialist in supplying mission- critical components to the Automotive Industry.

In response to the revamping and reorganization of the the Automotive Industry, Thuro has honed its focus to 2 areas of specialization, as follows:

Component Parts for Automotive Hydraulics
By providing Precision Machined Components to the Automotive Hydraulic Market for over 10 years, Thuro Metal Products has become a key supplier to North American and European- based assemblers of Automotive Hydraulic Systems. Specifically, Thuro specializes in the low to medium volume production of the critical, high precision components used in Radial Piston Pumps utilized for the hydraulic actuation of car top convertible systems, as well as hydraulic Lift Gate Systems.

Component Parts for Automotive Fuel Injection
Specializing in the production of Precision Machined Components for the Engine Management Systems, and more specifically, in components used in the Automotive Fuel Injection Market, Thuro Metal Products supplies millions of high precision components annually. Please see our past project titled,

All parts launched for automotive applications follow the process and documentation format as outlined in the Automotive Industry Action Groups Standards, also referred to as AIAG. For our European- based assemblers, we follow the guidelines of the Verband der Automobillindustrie, or VDA Standard. Early engagement with our clients, in order to understand the application and function of their systems, as well as the function and application of our components within the system, is the first step we take, usually months or even years prior to launching a new project so that we can design and document our process in accordance with Automotive Industry Standards, thereby creating our initial PFEMA or Process Failure Mode and Effects Analysis. After adequate client engagement occurs, we proceed with our initial process design, typically in the form of a flow chart and the initial process documentation is created by means of our Control Plan. Next we create a prototype. The majority of the projects we undertake involve a component which has been validated, tested and approved for production. This means that the purpose of our initial run, which we call a prototype run, is to test and validate our process, which includes testing and validating the initial work instructions, drawings, tooling, gages and fixtures, as well as checking the actual product throughput. We analyze the data, adjust the plan, do a rerun if any significant changes occur, check the results and act where necessary. After this process is completed, we are often audited on- site by the customer prior to the official launch. Typically, our parts run under PPAP are life cycle tested prior to launch. The process described above is in accordance with the method known as the PDCA cycle or simply the process of Planning, Doing, Checking and Acting, which was originally called the Deming Cycle. This cycle is repeated until the objectives, as outlined in the initial plan, are achieved.

When developing and validating our production process for a component which is also being developed and validated by our customer (not a frozen design), we ultimately follow the same steps for production launch. However, we work with our client’s Design and Application Engineers to first confirm basic materials, features and tolerances prior to creation of our PFEMA. We then provide our customer with a prototype for their testing and validation. This process may occur several times until the design is “frozen” and deemed by our customer, and typically by their customer as ready for use. We then proceed with the testing and validation of our production processes.
