How Does W.E. LOTT Assure Quality?

ISO 9001:2015

As our customer base widens, our exclusive list of industrial OEM manufacturers requires we meet the strictest manufacturing standards possible. We strive to find foundries, forge shops and machine shops that have ISO, AAR and other certifications and provide a series of quality control steps to suit the type of part being manufactured. These processes may include any or all of the following:

Material Certification

Materials are produced to either the customer’s requirements or a National Accepted Standard such as ASTM, ANSI, SAE, or UNS. Depending on the customer’s requirements, an independent laboratory will be used to perform and certify test data. We also perform incoming inspection of products, as needed, to verify dimensional, chemical and mechanical properties.

Material is not shipped until all data required is compiled and reviewed by the US office.

In-House Testing

  • Spectrometer for Chemistry
  • Rockwell Hardness
  • Brinell Hardness
  • Numerous Dimensional Instruments
  • Liquid Penatrant Inspection
  • Pressure Testing
