Get to know us
Family owned and operated, Southern Tier Plastics, Inc. (STP) has been producing Custom Injection Molded products since 1967. More than fifty years ago our founder, John Gwyn, who was already immersed in the plastic industry, started his own company based on three principals; Quality, Service and Delivery. Now in our third generation, we produce a wide array of products for clients worldwide utilizing these same three principals.
Quality Assurance and Control
Here at Southern Tier Plastics, Inc. quality is a top priority. As our customers' demand for quality products has been driven to a higher level, we have taken on this challenge openly. The implementation of Statistical Process Control (SPC) has been in place for decades. Continuous training of Southern Tier Plastics' employees ensures improvement in all aspects of manufacturing. ISO Certification was obtained in 2015 and we remain current in our ISO 9001:2015 certification. We have exceptional control through our Quality Management System and quality procedures. These fine tuned processes allow STP to meet and exceed our quality objectives. Our rigorous quality practices have allowed us to be FDA approved, as well as UL listed. Southern Tier Plastics, Inc. takes great pride in constantly making improvements to improve our quality systems.

Flexibility
Because of our small business platform we are able to remain flexible when it comes to our manufacturing processes and procedures. We have embraced lean manufacturing principles.
Southern Tier Plastics, Inc. also has the capability to warehouse your product in-house so we can release your time sensitive product exactly when you need. We can also set up consignment inventory at your location or utilize 3PL services to fit your stocking needs.
Environmentally Mindful
Being in the plastics manufacturing field can sometimes be conceived as harmful. We pride ourselves on keeping the wellbeing of the environment at the forefront of our operation. Southern Tier Plastics, Inc. uses a battery of plastic granulators to recycle our scrap. After the parts are granulated, our team uses the pellets to continue our production processes. This keeps our environmental footprint substantially small.
Custom Part and Tooling Design
At Southern Tier Plastics, Inc. we welcome and encourage concurrent engineering. A Design for Manufacturing (DFM) report with Mold Flow analysis is provided with every tool we build. Prior to ordering your tool you will have as much time as you need to review the design before steel is cut.
