Lawton Standard St. Paul establishes strict operating parameters with equally strict documentation to ensure that when a part rolls off our line, it’s ready for you.
We operate under a total quality system that guides everything we do – from purchasing and receiving to production to the shipment of the finished product. Our metallurgy department and statistical process control systems are solid. Our machine shop can handle everything we cast and has rapidly established a reputation for excellence.
These strengths are reflected daily in the exceptional quality of our finished parts. They are the reason we can consistently deliver 100% good parts.
In addition to being ISO Certified, Lawton Standard St. Paul has been audited and certified by WABTEC.
Lawton Standard St. Paul performs a full-dimensional layout. After a part enters production, it is dimensionally verified based on the pattern’s cycle count, which measures molds produced on a given pattern. This dimensional verification of the casting is done to monitor tooling wear.
Also, during the initial sampling phase, the casting process is further developed and verified through soundness evaluation by sectioning or radiographic examination. We section apart by sawing it in various orientations through the thicker cross sections of the casting.
Every heat lot is checked for hardness using a Brinell hardness tester. The hardness value is used as a process control parameter that closely follows the material’s mechanical properties. Our internal metallurgical software system records the hardness readings for a thorough evaluation.
In addition to a complete range of manual inspection tools, Lawton Standard St. Paul uses a Romer arm to precisely measure all finished iron castings. The Romer Arm is a manually operated coordinate measuring machine. It is accurate within thousandths of an inch, ensuring final iron castings meet quality requirements.
