Our Quality Assurance Mission

We work hand-in-hand with each customer to identify critical characteristics to help us develop and customize a quality control plan for each plastic injection molding product. This quality control plan is consistently followed and documented during every production step of your product order.

Precision Quality Assurance

We understand the importance of meeting critical dimensional tolerance requirements for our customers including healthcare and medical devices. Our creative approach to streamlined manufacturing and problem-solving allows us to manufacture high-quality complex components and assemblies economically.  Our quality control system is based on the principles of ISO- 9001:2015 with a comprehensive plan and system of procedures that guide our daily tasks and quality inspection on every production run. Every new project at Stelray begins with our quality inspection program review process to ensure we understand your product quality needs from the beginning.
