Manufacturing Quality Management & Process Control

We manufacture problem solving.

Repeatable Excellence

Lexington’s manufacturing quality management system is designed to ensure consistent, repeatable results across every production run. Through advanced process control systems, ISO-compliant procedures, and digital document control, we maintain accuracy from project setup through final production. Our commitment to quality assurance manufacturing helps customers reduce risk, improve performance, and maintain product consistency.

PPAP Validation & Manufacturing Quality Control

Production Part Approval Process (PPAP) allows our customers to review our step-by-step process for creating their components, even supplying test parts before we start large production runs. Whether we’re producing 50 or 50,000 of one particular part, we do everything we can to supply precise, highest quality parts. Our preventative maintenance practices, in-process inspections, Statistical Process Control (SPC) and quality audits confirm every part meets dimension and appearance specifications, so when the job is completed our customers get exactly what they ordered.

Our manufacturing quality control process includes Production Part Approval Process (PPAP) documentation, in-process inspections, Statistical Process Control (SPC), and preventative maintenance programs. These systems allow us to identify potential issues early, improve production consistency, and ensure every component meets customer specifications before shipment.

By utilizing Statistical Process Control (SPC), Lexington continuously monitors key manufacturing variables throughout production. This data-driven approach enables us to maintain tight tolerances, minimize variation, and support long-term process improvement initiatives.

Product Traceability & Material Verification

During the production process we frequently check materials to make sure they are within tolerance specifications. If non-conforming materials are found, we investigate and resolve the issue by removing and containing those parts from the production line. Our non-conforming materials protocol ensures any and all issues are resolved before production continues. Lexington’s date stamping capabilities will trace every piece and part all the way back to the raw materials. From what glue and paint was used to where the wood came from and when it was manufactured. We follow the American Society of Testing and Materials (ASTM) standards when testing our products and methods to ensure quality and customer satisfaction throughout the entire project.

Complete product traceability provides confidence throughout the supply chain. Lexington can track materials, components, finishes, adhesives, and production dates, creating a documented manufacturing history for every part produced. This level of visibility supports quality assurance, compliance requirements, and rapid issue resolution when needed.

Continuous Quality Improvement

Quality is more than inspection. Lexington applies continuous improvement principles to optimize workflows, reduce waste, increase efficiency, and enhance overall manufacturing performance. Through process audits, performance monitoring, and ongoing refinement of production methods, we help customers achieve reliable results while supporting long-term product quality goals.
