One-Stop Medical Service Robot Prototype Manufacturing | SGPROTO Precision Prototyping

Project Overview

SG PROTO has years of experience in CNC machining and surface finishing for medical devices and intelligent equipment.

In this project, we manufactured the housing for a medical service robot used in hospitals. These robots help deliver medicines, transport samples, distribute supplies, and guide patients in hospitals, clinics, and health check centers.

The customer provided CAD files and color requirements. They needed a complete solution, including:

Appearance prototype verification

Assembly and fit testing

Low-volume housing production

Painting and surface finishing

Final housing assembly

SG PROTO handled the entire project, from prototype machining to finished robot housings.

Complete Medical Robot Prototype Manufacturing Process

1. CNC Prototype Machining

 We started by machining the housing from ABS plastic using CNC milling.

The robot housing was divided into five separate parts: Base, Main body, Arms,

Head (with nurse cap) and tray. 

Each part was machined according to the customer's 3D CAD drawings with precise tolerances and proper assembly clearance.

 The smooth, curved surfaces accurately matched the robot's modern, friendly appearance.

After machining, every part was hand-sanded and test assembled to check the fit. Any interference between parts was corrected before production, helping the customer reduce development risk and avoid costly tooling changes later. 

2. Surface Finishing and Painting 

1) After machining, every housing went through several finishing steps,  including coarse sanding, fine sanding, and polishing.

 This removed CNC tool marks and created a smooth, seamless surface.

 2) Experienced painters then applied the final colors: 

Glossy medical white for the main body

Matte light gray for the arms

Red Cross logo on the nurse cap using separate masking and painting

3) We can also provide additional finishing services such as: 

Logo silk-screen printing

UV protective coating

Other custom cosmetic finishes 

 3. Ready-to-Ship Delivery 

After painting and assembly inspection, each robot housing was carefully packed for international shipping.

The package included:

 Custom EPE foam inserts

Reinforced cartons

Fragile warning labels

The customer received housings that were ready for installing motors, screens, sensors, and other internal components.

Project Results

This medical robot prototype manufacturing project demonstrates SG PROTO's complete manufacturing capabilities for robotics, from prototype development to low-volume production.

As AI service robots continue to evolve rapidly, manufacturers need faster product development and more flexible production.

With precision CNC machining and professional surface finishing, SGPROTO helps customers:

Build functional prototypes quickly

Shorten product development time

Reduce tooling investment

Produce high-quality housings for humanoid and commercial robots.

Trends in the AI Robot Industry

The AI robotics market is developing in several clear directions.

1) More application-specific robots

 Robots are being designed for healthcare, hotels, retail stores, factories, and many other industries. Most projects begin with small production volumes.

2) More complex product designs 

Robot housings are becoming more human-like, with larger curved surfaces and higher appearance requirements.

3) Lightweight hybrid structures 

Modern robots often combine plastic and metal components, making suppliers with both machining capabilities more valuable.

4) Faster product development 

Many companies now choose rapid prototyping and low-volume manufacturing before investing in injection molds. This reduces development time and lowers project costs.
