Saftty's Six-Pillar Reliability System

I. Thorough Customer Needs Analysis

hermal protectors are essential parts inside electrical devices. Since different products and industries have varied environments and requirements, it’s crucial to understand the real use cases. Even if a device meets standards like UL or VDE, unexpected problems can still occur, which may affect the protector’s performance.

||. Reliability Design Management

High-quality products stem from scientific design and precise manufacturing, rather than relying on inspection and selection. Relying solely on inspection to pick products is inefficient, costly, and cannot guarantee stable performance in actual use.
Saftty’s reliability design management system includes:
①Reliability review and project management;
②Product design training;
③Process design training;
④Development of checklists (CHKLIST);
⑤Test report templates;
⑥Design review report templates;
⑦Review and reward management system.

|||. Material Selection & Certification

The reliability of a thermal protector depends on the quality of every component. Saftty enforces strict material selection and certification to ensure product consistency from the source.
Key measures include:
①Material selection and substitution process;
②Inspection and issue handling procedures;
③Preferred materials list and selection guidelines;
④Custom part control;
⑤Supplier qualification and management.

IV. Assembly reliability management

Assembly quality is essential to product performance. Saftty has established standardized processes and promotes full automation to ensure consistency and stability.
Focus areas include:
①Component assembly design standards;
②Incoming and outsourced parts inspection;
③Work instructions and process control;
④Automation to replace manual operations;
Currently,70% of production at the Yangzhou plant is automated, with full-process automation as the future goal.

V. Failure analysis management

Each failure is a chance to improve reliability. More resolved cases mean fewer failures in the future.
Process:
①Collect data and plan analysis;
②Inspect and test samples;
③Open samples, locate failure point;
④Analyze cause;
⑤Apply and verify corrective actions.

VI. Data Management Platform

All reliability files and specs are managed on a unified platform for consistency and easy access.
Covers:
①Product, component, production, and training documents;
②Material and document changes, impact analysis;
③Secure sharing across teams.
