Quality Assurance

Certified Quality Plan

GLMF offers many colors and the fastest turn around times in the industry, but we know that it means nothing without quality. With careful attention to chemistry, we control our tank line to ensure that your parts are processed correctly. This allows us to provide you with both the highest quality metal finishing along with repeated cosmetic quality. Our Quality Plan is certified to ISO9001:2015. We also hold the aerospace certification AS9100D as well as accreditation from PRI for NADCAP. We run our daily operations to these standards, which allows us to provide our customers with consistent quality.

Clean Water

A majority of chemicals are rinsed back into the process tanks, to minimize drag-out. The continuous flow of rinse water in our tanks prevents any cross contamination of chemicals, which allows for very clean rinse tanks and optimum performance for our process tanks. This allows us to reduce chemical costs while being environmentally friendly.

Process Controls

Processes are controlled using TrueChem© software, which allows us to closely monitor our control limits and specification limits. This software also helps to continually improve shop targets.

  • Chemistry: We titrate our tanks on a regular time schedule to ensure that the chemical concentrations are always correct.
  • Temperature: Tank temperatures are checked daily so that the chemicals perform properly.
  • Time: Operators follow strict control plans, which outline the amount of time that the parts spend in each bath. Results are recorded and data is stored for traceability purposes in our paperless system.


GLMF is approved by Nadcap, ISO 9001, AS9100D, Parker Hannafin, BAE Systems, Eaton, and has their FFL license. GLMF is also ITAR and RoHS compliant.
