Precision Manufacturing, Collaborative Excellence: The Chang'an Sister Factory Alliance – Your One-Stop Solution for Hardware Development


Strategic Location, Industrial Synergy Based in Dongguan Chang'an, the global epicenter of manufacturing, each facility is unique in manufacturing a wide range of molded parts. we leverage the dense industrial ecosystem of the Pearl River Delta. Collaborating with sister factories within the same town, our network ensures seamless resource integration and cost efficiency, reducing project lead times and logistics costs for clients.


Diverse Expertise, End-to-End SolutionsThe Sister Factory Alliance specializes in 10+ advanced manufacturing technologies:

　




Silicone site Specializes In  Custom  Silicone Compression tooling and molded parts.  includes: Rapid Prototyping Development & Tools and OEM rubber items such as Sexual-Wellness-Products

　

Thermoset composites deliver custom  manufactured thermoset products and innovative solutions. They offer a wide range of thermoset molding of BMC, SMC capabilities from design, development and mold making processes to ensure consistent, quality results.

　

We have a paint processing workshop allowing us to apply virtually any type of commercially-available custom paints for your prototypes or low-volume manufactured parts. Our technicians are able to produce any desired surface finish, including high gloss, matte, semi-gloss, spraying, silk printing,etc





● CNC Precision Machining: Aluminum, stainless steel components with ±0.01mm tolerance

● Sheet Metal Fabrication: Laser cutting, bending, welding for custom enclosures

● Silicone & Plastic Molding: Liquid silicone injection (LSI), thermoset compression molding

● Metal Injection Molding (MIM): Complex microstructures for high-volume production
