Comprehensive heat treating and complementary precision manufacturing services integrated seamlessly into your project workflow.
Precision heat-treat processing coordinated through certified supply partners to enhance material hardness, strength, and durability for machined and fabricated metal components in demanding applications.
Controlled hardening and tempering processes to optimize the mechanical properties of steel and metal alloys, ensuring components meet exact metallurgical specifications for aerospace, defense, and industrial use.
Advanced CNC machining and full-scope fabrication from concept to installation, machining components up to 20,000 lbs with tolerances as tight as +/-.0005, fully integrated with heat treat workflows.
Rigorous post-heat-treat inspection using CMM analysis, first article inspection reporting, and dimensional verification on certified granite tables to confirm metallurgical and dimensional compliance.
Industrial plating integrated within the project workflow to deliver surface protection and functional finishes meeting corrosion resistance, conductivity, and wear performance specifications.
In-house thermoset powder coating and blast preparation for custom metal parts and fabricated assemblies, offering corrosion, UV, and abrasion-resistant finishes as part of a complete manufacturing solution.
We begin by thoroughly reviewing your component specifications, material types, and metallurgical requirements. Our team assesses hardness targets, industry compliance standards (aerospace, defense, industrial), and project timelines to build a precise treatment plan.
