COROTC coordinates production with 10 audited partner factories. The process covers raw material inspection, semi-finished product assembly and testing, in-process QC, final assembly and packaging. Production photos, inspection records and third-party reports are available for buyer review upon request.

We support private label, drawing-based and sample-based customization for welding and cutting equipment. Our team coordinates requirement review, product matching, logo, color, panel and packaging options, sample confirmation and bulk order follow-up with partner factories. Available options depend on the model and project scope.

Product development support is coordinated with engineering teams at our partner factories. We assist with specification review, application matching, prototype and sample evaluation, and product improvements based on distributor and end-user feedback. Project drawings and test records are available for review when applicable.
