What Quality Means to Five Star

Four Operational Standards Built Into Every Part

For our customers, high quality means repeatable fit, flawless finishes, failure-free assembly, and no product recalls — thus resulting in a satisfied end user. Quality management is fully integrated into business processes across the company.

Repeatable Fit

Dimensional consistency across every part, every run, every order — repeatable to specification regardless of production volume.

Flawless Finishes

Cosmetic purity, optical clarity, and finish consistency — Class-A surfaces that meet OEM appearance standards on the first try.

Failure-Free Assembly

Parts that install and perform exactly as engineered — tolerances held tight to integrate cleanly into the customer's assembly line.

No Product Recalls

The ultimate quality outcome — components that perform reliably across the product lifecycle, protecting our customers' brands.

Employee Certifications

Trained in the Industry's Gold-Standard Quality Programs

A number of Five Star employees are certified in PPAP, PFMEA, and Lean Six Sigma quality management programs — the three certifications that define rigorous OEM manufacturing supplier qualification.

Quality Program PPAP Production Part Approval Process

The automotive industry's foundational supplier qualification framework — used by OEMs and Tier 1 suppliers to validate that every production process can repeatedly produce parts meeting all engineering and quality specifications, run after run.

Quality Program PFMEA Process Failure Mode & Effects Analysis

A proactive risk management discipline — systematically identifying potential process failures, assessing their impact, and implementing controls before defects can reach customers. The engineering backbone of preventative quality.

Quality Program Lean Six Sigma Process Excellence Methodology

The data-driven methodology behind world-class manufacturing — combining Lean's waste-elimination principles with Six Sigma's defect-reduction statistical rigor to deliver shorter development cycles and consistently higher quality.

Understanding ISO 9001:2015

What Is ISO 9001:2015 — & Why It Matters

In order for a company to obtain ISO registration, it must put a system in place across the entire organization that implements and constantly conforms to principles required by the ISO 9001 standard. For OEM procurement teams, ISO 9001:2015 certification signals that supplier quality isn't ad-hoc — it's structurally embedded in how the company operates every day.

Continually strive to improve the company

Monitor the performance of vendors

Monitor customer perception and maintain a method for dealing with customer complaints

Audit processes regularly and submit to periodic outside audits

Incorporate a corrective & preventative action system

Analyze data rigorously and systematically

And much, much more — full organizational compliance is what ISO certification actually means
