Project Scope
Anomatic Corporation used anodizing to achieve a consistent matte finish with very tight tolerances for a disposal lighter flame shield for a major U.S. consumer products company.

Challenge
The customer wanted flame shields with a consistent matte finish and very tight tolerances throughout millions of units. However, one of the core challenges was to manufacture repeatability without a negative impact to finish quality from part to part and run to run. Since the anodizing process actually "grows" the part dimensionally, extremely tight process controls are required to maintain thickness across millions of parts consistently.

Solution
Anomatic provided product engineering and process engineering expertise for both fabrication and finishing needs of the component. They sourced a qualified vendor for the four slide fabricated aluminum shell. Using a custom conveying anodizing system and an internally developed chemical bath formulation for etching the metal, they were able to achieve a consistent matte finish while holding a very tight tolerance. This process has allowed Anomatic to deliver 70 million units each year for over 10 years. "Challenge solved!
