Complete Manufacturing Workflow
Complex products often require different materials and manufacturing technologies. By coordinating these processes through one manufacturing partner, customers can simplify communication, production scheduling, quality control, and logistics.
Complete Workflow:
Design Review → DFM → Metal & Plastic Parts Production → Surface Finishing → Quality Inspection → Assembly → Functional Check → Packaging
Quality Assurance
Quality control is performed throughout production, from individual components to completed assembly:
- Dimensional inspection
- CMM inspection
- Critical feature measurement
- Material certification
- Surface inspection
- Assembly inspection
- Functional testing
- First Article Inspection
- Final inspection reports
Industry Applications
Our services are suitable for:
- Industrial automation
- Robotics
- Electronics
- Power equipment
- Telecommunications
- Automotive equipment
- Medical equipment
- Aerospace applications
- Semiconductor equipment
- Laboratory equipment
- Precision machinery
- Custom mechanical systems
Production Scale Flexibility
Prototype: Produce initial metal and plastic components for design verification and functional testing.
Small-Batch Production: Manufacture customized components for pilot production and product validation.
Mass Production: Provide repeatable manufacturing and assembly for established products with ongoing production requirements.
This allows customers to continue working with the same manufacturing partner as their products move from development into production.
