Metal Pre & Post Treatment

Why Are Pre & Post Treatments Important?
AOTCO's Finishing Techniques

While there are a wide range of benefits and positives that can be gained from an effective surface finishing solution, but oftentimes extra surface protection or additional coating are required for a component to operate effectively. This is where post treatment processes come in.

At AOTCO, we offer several post process treatments, such as: laser marking and engraving, Hydrogen embrittlement stress relief, and electropolishing.
