High-Temperature Injection Molding
At The Toolroom, we’ve been at the forefront of precision plastic injection molding since 1978. Over the years, we’ve honed our expertise to cater to the most demanding applications, including the specialized field of high-temperature injection molding. This advanced process is essential for producing components that must endure extreme conditions without compromising performance.
Standard injection molding typically processes materials at temperatures between 300°F and 500°F, but high-temperature molding operates in a much more demanding range—up to 700°F or higher. This extreme heat is necessary for engineering-grade resins like PEEK, PEI (Ultem), PPS, and other high-performance thermoplastics that can’t be molded effectively at lower temperatures.
The key difference is material behavior with mold design. High-temperature materials have higher melt viscosities, meaning they require more heat and pressure to flow properly into the mold. The molds must also be constructed from specialized steels and often include heating elements to maintain optimal temperatures throughout the cycle.
The Toolroom’s facility is equipped with state-of-the-art machinery capable of handling the rigorous demands of high-temperature molding. We employ specialized mold base systems designed to endure elevated temperatures, incorporating features like advanced cooling channels and insulating materials to maintain process stability. This infrastructure enables us to produce parts with superior dimensional accuracy and surface finish, even when dealing with complex geometries.
What are the advantages of high-temperature injection molding?
- Unmatched material performance. High-temperature plastics retain their structural integrity in extreme environments—think aerospace components, medical sterilization trays, or automotive under-the-hood parts. These materials resist warping, chemical degradation, and mechanical stress far better than standard plastics.
- Tight tolerances and superior finish. Because high-temp molding involves precise control over cooling rates and pressure, the resulting parts exhibit exceptional dimensional accuracy and surface quality. This is critical for industries like medical devices, where even micron-level deviations can impact performance.
- Longer tool life when the process is done right. While high-temp molding is more demanding on equipment, working with an experienced manufacturer like The Toolroom ensures that your molds are built to last. We use hardened steels and advanced thermal management techniques to prevent premature wear.
