Quality Assurance
Built for Consistency, Not Just Compliance
A structured quality system designed to support long-term OEM/ODM programs with consistency, traceability, and controlled risk.
Our Quality Philosophy
At Mustar, quality is not treated as a final inspection step. It is built into every stage of
product development and manufacturing.
We believe that stable quality comes from clear specifications, controlled processes, and disciplined execution — not from inspection alone.
Our quality system is designed to support long-term production programs, where consistency over time matters as much as initial performance.
Quality Built into the Process
By embedding quality planning into every stage, we reduce variability and prevent issues before
they reach mass production.
In-house Control & Traceability
Key manufacturing processes are managed in-house, allowing Mustar to maintain tighter control over quality and traceability.
Faster issue identification and response
Clear linkage between materials, processes, and finished products
Consistent execution across multiple production batches
Traceability records for internal review and customer communication
Change Control & Continuous Improvement
Uncontrolled changes are one of the biggest risks to long-term quality consistency.
Mustar applies change control procedures to ensure that any modification — whether in materials, processes, or specifications — is reviewed, documented, and approved before implementation.
Feedback from production and the field is used to drive continuous improvement while maintaining stability for ongoing programs.
