2. Initial Order Communication Process

German industrial manufacturing boasts the world’s top standards for the flatness, dimensional tolerance, material strength, surface technology and assembly conformity of robot shells. Local German robot manufacturers implement extremely strict access audits for external component suppliers. The cooperating customer in this project is a well-known automation technology enterprise based in Bavaria, Germany. It specializes in the R&D and production of light-duty collaborative robots and desktop industrial robots, with products mainly supplied to automotive component and 3C precision processing factories across Europe. The company sets rigorous standards for the structural stability, lightweight performance, corrosion resistance and yield rate of robot shell components.

The cooperation originated from the Munich Automation Exhibition in Germany. The customer compared products from multiple suppliers on-site, focusing on the wall thickness uniformity, hole opening accuracy, surface spraying technology and overall structural rigidity of robot shells. Our integrally formed robot structural shells stood out with no deformation, precise hole positions, delicate paint finish and high strength with lightweight features, attracting in-depth technical communication with the customer’s technical team.

The customer remained cautious at the initial stage of cooperation. It had long-term partnerships with local European sheet metal and precision die-casting manufacturers, and doubted the process consistency, mass production yield rate and adaptability to German industrial standards of Chinese structural parts. Initially, it only intended for small-batch sampling and refused mass procurement cooperation. After the exhibition, our business and technical teams followed up continuously, maintained close communication with the customer’s R&D department, sent product samples, and provided material test reports and process parameter documents. After three months of technical running-in and sample testing, the customer officially launched negotiations for mass cooperation.

3. Core Customer Requirements and Cooperation Challenges

For its new mass-produced robot model, the customer put forward multiple high-standard customized requirements for shell structural parts, bringing several core challenges to project implementation:

1. Ultra-high Dimensional Tolerance Requirements: The customer adopts fully automated assembly lines for complete robot machine assembly, requiring the hole position error of all shell accessories to be within ±0.03mm, with unified flatness and assembly conformity for all parts.
