Design & Engineering Support | Design for Plastic and Silicone Parts Manufacturing

Key Takeaways
• Design and engineering support focused on real factory production (Design for Manufacturability)
• Covers plastic, silicone, and multi-material industrial parts
• Reduces manufacturing issues such as warpage, assembly difficulty, and quality variation
• Links design with mold making and production to reduce lead time and improve yield
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
■ Design for Manufacturability in High-Precision Industries
In high-precision manufacturing, design that does not align with actual production processes often leads to repeated revisions, longer development time, and increased costs.
SUNARROW CITI CO., LTD. provides Design & Engineering Support focused on manufacturable design, ensuring stable and long-term industrial production.
■ Design Scope and Supported Part Types
We support design and engineering for a wide range of industrial parts, especially plastic parts, silicone parts, and multi-material components such as plastic-rubber and plastic-metal assemblies.
These parts are used in automotive, electronics, medical devices, and other industrial products requiring high precision and consistent quality.
■ Design Evaluation to Prevent Manufacturing Issues
Our support goes beyond drawing review. We evaluate part structures considering injection molding, assembly, and quality control.
Key factors include wall thickness, geometry, draft angles, assembly points, and surface conditions to prevent issues such as warpage, surface defects, assembly difficulty, and quality variation during mass production.
■ Connecting Design with Mold and Production Processes
Design is closely linked with mold manufacturing and in-house production processes.
This approach reduces design changes, shortens development lead time, and improves yield in actual production lines.
📘 Summary
SUNARROW CITI’s Design & Engineering Support bridges design and manufacturing, reduces quality risks, and supports efficient, stable industrial production.
