High Quality Castings – Lodi’s Top Priority!

We adhere to Lean Manufacturing Principles where continuous improvement is an ongoing effort to reduce waste, increase quality, and deliver castings in the most economical way.  As a result, our quality program begins with the end in mind. 

Whether you need iron or steel castings, you can depend on Lodi quality. Our established inspection system meets or exceeds the requirements of MIL-I-45208A.

LODI proudly holds the Certified ITAR Professional®Certification which ensures that we have an expert working knowledge of exporting and importing under the U.S. Department of State Directorate of Defense Trade Controls' (DDTC) International Traffic in Arms Regulations (ITAR). Lodi is also one of few foundries in the U.S. to be on the Lloyds approved supplier list. To see our Lloyds certificate Click Here.

We conduct scores of tests to meet SAE, AISI, ASTM and AMS standards and specifications. Castings are checked for integrity, soundness, dimensional accuracy and finish, to name a few. If castings don’t shape up, we don’t ship them out – it’s that simple.

Quality Management System     

Our motto is conformance to customers’ requirements under the strict guidelines of our Quality Management System, which is based on the requirements of ISO 9001 and AS9100. No job is too small for us when it comes to quality control and assurance.

The Lodi Quality Control Department conducts a broad spectrum of laboratory tests to ensure the quality of our sand system. This includes methylene blue, green compression strength, moisture, compactability, loss on ignition, hardness, etc. Dimensional inspection of first article castings is performed to validate the pattern. Brinell Hardness Testing is a regular feature of our Quality Inspection. QC checks the chemical composition of each heat of metal using our in-house spectrometer.
