China Robot Welding Service & Exporter

Critical CNC-milled and turned features can be held to ±0.005 mm, with ±0.01 mm standard on precision mating faces. In welded assemblies, our robotic fixtures and calibrated weld sequencing hold overall geometric tolerances to within ±0.15 mm to ±0.25 mm depending on part geometry and parent metal grade, with critical mounting points CNC-finished in a secondary setup.

CNC machining, metal stamping, and specialized assembly run in Sunmy-owned facilities. Casting, specialized surface plating, and high-volume sheet blanking are produced by audited long-term partner plants. All quality assurance, CMM dimensional verification, and First Article Inspection (FAI) reports are executed directly in-house by Sunmy engineers before overseas shipment.

We sign strict Non-Disclosure Agreements (NDAs) directly with your company before receiving any proprietary 3D/CAD drawings. Because you interface directly with our engineering factory staff rather than external sales agents or trading brokers, your intellectual property remains secure within our controlled enterprise network.

Every shipment can include standard Raw Material Certificates (traceable EN 10204 3.1 chemical & physical mill test reports), in-house CMM inspection logs, FAI documentation, surface finish roughness data, and RoHS/REACH compliance declarations where required.

Yes. We support early-stage development and low-volume pilot batches through multi-axis CNC machining, 3D printing, and urethane casting. Once initial verification passes, we scale production seamlessly into automated robotic welding cells, progressive stamping dies, or high-pressure die casting without switching vendor teams.

Our engineering team reviews 2D/3D technical drawings and project briefs within 24 hours, providing initial DFM feedback, proposed tooling routes, unit cost estimates, and risk analyses before commercial engagement.
