Mechanical seals are to seal the openings of and joints between mechanisms to contain pressure and form a barrier to prevent the fluid (water or oil) used by a machine from leaking to the external environment. Commonly used in pumps, motors, compressors, and stationary equipment, seals are one of the most essential components to ensure a machine functions reliably and effectively.
Seals, especially those that mate to moving parts, have a demanding set of exacting quality requirements to ensure a proper fit and durability. Each industrial application has its own specific needs, but all seals must be engineered to deal with tight dimensional tolerances and have an excellent surface finish. Our proprietary process can attain 0.0003 tolerance.
Polymer materials are an excellent choice for high-performance, high-pressure environments. And if exacting dimensions and tight tolerances are involved, injection molding is the best method to produce the needed results. Performance Plastics specializes in injection molded polymer seals, custom-engineered and net shape-molded to meet or exceed your requirements.
With our injection molding technology, we can produce near-net shape seals high-performance materials like PEEK, Torlon (PAI), PFA, FEP & Teflon. The process greatly improves the integrity of the seal, eliminating voids, sinks, or porosity, for stronger, more reliable parts with more consistent mechanical properties.
When there is an extreme application and mechanical failure is not an option, you need to make sure your parts will work. Our team of exceptional engineers have decades of experience in designing technically challenging and complex solutions across a wide range of industries. With their in-depth of knowledge in resin formulations, they can choose the right material for the job.

Ensuring a tight seal in fluid or gas applications is critical in mechanical systems to eliminate leaks, reduce costs, and increase productivity. Air compressor seals prevent the process gas in the compressor from getting to the atmosphere and conversely prevents the atmosphere from getting into the process gas. Compressor oil seals are designed to force oil into the compressor seals at a higher pressure than the process gas. High and ultra-high-performance polymers are the preferred material for these types of applications, and precision injection molding of the parts provides the ability to meet the most demanding dimensional tolerances and specs.
