This article will use a case study of robot industry parts manufactured by Kaierwo to introduce how Kaierwo uses CNC machining and molding processes to reproduce customer designs.
| Project Introduction | This project was commissioned by a smart service robot manufacturer to produce a life-size prototype robot shell for demonstration and assembly testing. The client requires the shell to have a stylish and eye-catching overall appearance, a rigorous structure, and a high-gloss surface with a near-production-ready appearance. | Industry | Robots |
| Name | Robot Shell | ||
| Material | ABS+PMMA | ||
| Process | CNC machining + Molding | ||
| Surface Treatment | Spray Painting + Masking and Color Separation Spray Painting | ||
| Machining Challenges | Achieving seamless assembly through a combination of fine surface polishing and precise machining. | ||
| Solution | Programming to design reasonable assembly gaps and strictly controlling machining precision tolerances. | ||
| Project Cycle | 50 sets per month |
The robot's shell features a large curved surface and a two-tone yellow and black design. The client required seamless transitions between different color areas, with no gaps between the seams, strict control over overall dimensions, and a high-gloss, scratch-resistant surface. The complex curved shape placed high demands on CNC programming paths, assembly precision, and surface finishing.
After analyzing the 3D model, our engineering team divided the robot's shell into multiple modular components to facilitate efficient processing and precise assembly. We selected ABS and PMMA materials, which are easy to process and have excellent formability. Through five-axis CNC milling, we achieved surface consistency for each component and tight control at the joints. To ensure a perfect fit for the yellow and black color-blocked components, we used locating pins for trial assembly and calibration before painting.
The final prototype perfectly replicated the design intent in both appearance and structure, with smooth curved surface transitions, precise seams, a full-bodied gloss, and a texture approaching that of mass-produced parts. The client was extremely satisfied with the overall result and used the prototype for display at industry exhibitions, where it received high praise from visitors.
