Our Quality Assurance System
Dongguan Tengtu Aluminum Products Co., Ltd. has obtained ISO 9001:2015 Quality Management System certification. Our quality assurance system covers customer requirement confirmation, production process control, inspection records, non-conforming product handling, and continuous improvement, helping ensure clear quality standards and traceable execution records for each project.
First Article Inspection (FAI)
Before mass production, we can perform First Article Inspection based on the confirmed drawings, samples, and technical requirements, focusing on product dimensions, tolerances, materials, surface treatment, and assembly requirements.
SPC Process Control
For critical dimensions, repeat production orders, and long-term supply projects, we can apply SPC process control according to project requirements to monitor key production parameters and dimensional variation during production.
For die casting parts or components with internal quality requirements, X-ray / Non-Destructive Testing can be arranged according to the product structure and customer requirements.
