Sub-Assembly Services
RMS Group offers professional sub-assembly services for OEMs and industrial customers worldwide. We specialize in sub-assemblies of metal components integrated with rubber, plastic, and spring parts.
A sub-assembly is a partially assembled unit made up of multiple components that form part of a larger final product. By outsourcing sub-assembly services to RMS Group, customers benefit from consistent quality, simplified supply chains, and faster time-to-market.
What Is a Sub-Assembly?
A sub-assembly is an intermediate assembly created by combining two or more components into a functional unit before final product assembly. These assemblies are commonly used in mechanical, electrical, and industrial systems where precision, alignment, and repeatability are essential.
Key Benefits:
- Reduced in-house assembly time
- Improved consistency and quality
- Lower overall production costs
- Simplified sourcing and logistics
- Faster final assembly operations
