Overview & Use Cases
Matériel capable Solutions hub connects your industry needs to our custom metal fabrication capability in China. We design and build welded steel assemblies—machine frames, trolley/utility carts, produits de fil, and precision parts—using automatic/robotic MIG (TIG where specified) plus Usinage CNC and finishing. Each solution is engineered to drawing with documented QA and export-ready packaging, so your teams receive parts that fit, align, and last across global deployments.
Why this solution for demanding industry environments
Industrial programs succeed when suppliers combine repeatable processes, tight dimensional control, et reliable finishes. Our automated welding cells, custom jigs/fixtures, and controlled heat input deliver consistent geometry; our machining and coating workflows complete the stack so assemblies resist vibration, impact, et corrosion. For process details, see fabrication services et traitement de surface.
