Stelray Plastic Products is a leading global custom plastic injection molding company providing cost-effective solutions across a wide array of applications and industries.

As a full-service American Injection Molding Institute, we offer in-house mold tooling, mold design and engineering support, and custom manufacturing for a variety of plastic injection molded products all in our North East Injection Molding facility. Backed by advanced machinery and seasoned expertise, our facility is fully prepared for large part injection molding, ensuring precision and efficiency at scale. Our clients include top U.S. and international brands such as ITT, Panasonic, Hill-Rom, Hubbell, Sub-Zero and Welch Allyn.

Our Connecticut Injection Molding facility is ISO 9001:2015 certified to ensure that every project we take on meets all applicable quality requirements. We also are an FDA Registered Plastic Manufacturing Company and compliant with 21 CFR 820 and Good Manufacturing Practices, among other plastic industry certifications and standards.

All design and manufacture of tooling is done by our team—for a complete custom application. As a plastic products company, we offer a range of post-mold secondary operations, including ultrasonic welding, pad printing, heat-staking, soldering, assembly, and packaging as a part of our plastic injection molding services. Our engineering staff and machine technicians are experienced in a broad range of plastic resins; everything from commodity-grade to engineering-performance polymers and exotic resins. Given this knowledge, we can help guide you in selecting the best material for your project. We also offer biodegradable plastic resins when appropriate.

Every new project at Stelray begins with a preliminary plastic design for manufacturing (DFM) review to ensure that we understand your plastic product needs from the beginning. Our comprehensive precision quality assurance systems ensure that the components you pay for are exactly what you need. Our range of custom plastic injection molding services and creative approach to streamlined manufacturing problem-solving also allows us to manufacture high-quality complex components and assemblies at the best possible price.
