1. Project Overview: Developing a Reliable Metal Connection Solution for Smart Cradle Systems
With the increasing popularity of smart baby care products, motorized cradle systems are becoming an important solution for providing a more comfortable sleeping environment for infants. The motor connection mechanism needs to work smoothly and reliably during continuous operation, which places higher requirements on the strength, stability, and durability of internal metal structural components.
In this project, Innoway Precision was responsible for manufacturing a customized metal structural component used in a smart baby cradle motor system. Although the part looks simple, it plays an important role in supporting the connection between the motor system and the cradle structure.
The component needed to achieve a balance between mechanical strength, production efficiency, surface protection, and consistent quality for mass production.


2. Manufacturing Challenges
During the product development stage, several manufacturing challenges needed to be considered.
2.1 Ensuring structural strength under repeated movement
Since the component works together with a motor-driven rocking mechanism, it experiences continuous dynamic loading during operation. The material selection and forming process needed to ensure sufficient strength and long-term reliability.
2.2 Maintaining dimensional accuracy after stamping
The main forming process of the part is stamping. However, stamping can sometimes create sharp edges, deformation, or dimensional variation, which may affect assembly performance.
2.3. Improving edge quality and appearance
The stamped part required additional finishing on specific areas. Sharp edges or uneven corners could influence assembly safety and the overall product quality.
2.4 Balancing cost and performance
The customer required different material options depending on application requirements:
- Q235 carbon steel for cost-effective production, combined with color zinc plating for corrosion protection.
- SUS304 stainless steel for applications requiring higher corrosion resistance and durability.
The manufacturing process needed to support both performance requirements and production efficiency.
3. Engineering Approach
Based on the product requirements, Innoway Precision developed a manufacturing process combining precision stamping and CNC chamfering.
3.1 Stamping Process Optimization
The initial shape of the component was produced through stamping, which provided:
- Stable production efficiency for mass manufacturing
- Consistent part repeatability
- Better material utilization
During the stamping process, we controlled forming parameters to minimize deformation and maintain the required dimensions.
3.2 CNC Chamfering After Stamping
After stamping, CNC machining was added to finish critical edges and corners.
This secondary machining process helped to:
- Remove sharp edges
- Improve assembly smoothness
- Achieve better dimensional consistency
- Enhance the overall appearance of the component
By combining stamping efficiency with CNC precision, the part achieved both production capacity and quality requirements.
3.3 Material and Surface Treatment Selection
Two material solutions were provided according to customer needs:
Q235 Steel + Color Zinc Plating: Suitable for cost-sensitive applications. The zinc coating improves corrosion resistance and provides a stable surface finish.
SUS304 Stainless Steel: Suitable for applications requiring better corrosion resistance and longer service life.
4. Project Outcome
Through process optimization and close communication with the customer, Innoway Precision successfully delivered a reliable metal structural solution for the motorized cradle system.
The final product achieved:
- Stable mechanical performance during repeated operation
- Smooth edges and improved assembly experience
- Consistent quality suitable for mass production
- Flexible material options for different application requirements


This project also demonstrates Innoway Precision’s capability in developing customized metal components that combine stamping, CNC secondary processing, and surface treatment. From prototype evaluation to production support, we help customers transform functional designs into reliable manufactured products.
