Quality Management

We always think tubing

Quality Control

01 Customer requirement satisfaction through consistent raw material management inner process inspection and outgoing inspection
02 Minimizing measurement errors through education and training, digitalization and noncontact measurement
03 Process management for traceability

Quality Assurance

01 Maintaining QMS with ISO9001 and ISO13485
02 RoHS acquisition, patent application, product stabilization and improvement of process technology
03 Customer complaints handling

Research and Development

01 Inventive cold drawing technology accumulation and dies & plug changing system management
02 Continuously factory automation & welding mill line & annealing line & straightening standards
03 Operation of Research Institute and new product development
