AI for metal finishing job shops, starting with the traveler and the cert.

You work on parts you don't own. The Census Bureau's industry codes define plating and anodizing shops (332813) and heat treaters (332811) by doing that work for the trade, and powder coating sits in the same family of codes. EPA's metal finishing rule uses the same idea: a job shop owns no more than half, by annual area, of the materials it finishes. So each lot lands with a customer's purchase order, that customer's print and a packing slip, and all three describe the job in their own way. Someone in your front office has to settle them before a rack gets loaded or a furnace gets charged.

Shipped lots are the answer key. A lot that already left your dock also left the traveler that ran it and the certificate that went with it. Those two records let your reviewer score an AI draft against what your team actually wrote, field by field, so nobody has to imagine what a good answer looks like.

Vehicle customers bring their own layer. AIAG publishes special process assessments for this trade: CQI-9 for heat treat, CQI-11 for plating and CQI-12 for coating, the last written as a common approach to a coating management system for automotive production and service part organizations. A customer working from those can ask for records a general industrial order never mentions, so your reviewer should pick lots from both kinds of customer.

Regulated paperwork comes later, and a person owns it. EPA's Part 433 reaches electroplating, electroless plating, anodizing, coating, chemical etching and milling and circuit board manufacture, yet it leaves out existing job shops that discharge to a sewer and fall under Part 413. Wastewater treatment sludge from electroplating is listed waste F006, except from processes such as sulfuric acid anodizing of aluminum or segregated zinc plating on carbon steel, and F010 through F012 cover heat treating residues where cyanides are used. A chrome tank controlled by a wetting agent fume suppressant has a bath surface tension limit under 40 CFR 63.342: 40 dynes per centimeter by stalagmometer, 33 by tensiometer. Which of these reaches your shop is for your permit writer or counsel, and nothing here is legal advice, which is why waste and discharge records sit last on this list.

One limit covers every job here. The proof of concept never touches your ERP, your shop system, your lab equipment or a live traveler or certificate, and it never decides that a lot passes a specification. A person checks every traveler, and quality staff sign every certificate. Defense and aerospace work stays out of the sample.
