The Cryogenic Institute of New England is pleased to announce that Tri-Mack Plastics has awarded us its 2021 Supplier Excellence Award for our Nitrofreeze® cryogenic solutions. This is the first time that the Bristol, Rhode Island plastics manufacturer has recognized a supplier for consistently demonstrating excellence in terms of quality, on-time delivery, responsiveness, price competitiveness, and commitment to continuous improvement throughout the year.
In a letter from Tri-Mack, the company’s Operations Manager, Mike Jasmin, told Nitrofreeze® that “our ability to achieve our goals largely depends on your day-in and day-out performance as a key external supplier.” Jasmin added that “only a fraction of our suppliers perform at this level,” and praised Nitrofreeze® for “consistently maintaining focus on the details that are required to achieve this performance.” The Operations Manager also thanked Nitrofreeze® for our “unwavering support.”
Nitrofreeze® and Tri-Mack Plastics
The Cryogenic Institute of New England is located in Worcester, Massachusetts and committed to meeting the most demanding requirements through excellence in workmanship and strict adherence to ISO 9001 standards. Our Nitrofreeze® cryogenic solutions include cryogenic deflashing, cryogenic deburring, dry ice blasting, cryogenic treatment, and custom cryogenic processing. Turnaround times for deflashing and deburring projects are just two days.
Tri-Mack is an ISO 9001:2008, AS-9100, and NADCAP certified manufacturer that specializes in precision parts for aerospace applications. This engineering-driven company provides plastic molding and plastic machining services to customers who require tight-tolerance components with complex geometries. Tri-Mack’s manufacturing capabilities include injection molding, compression molding, and hybrid molding for advanced engineering plastics that need to withstand demanding conditions.
Cryogenic Deflashing for Molded Parts
Nitrofreeze® cryogenic deflashing is a safe, efficient, and cost-effective way to remove mold flash from parts like aerospace components. Flash, or flashing, is excess material that’s left behind by the molding process. Although flash-less tooling is available, all molded parts have some amount of flash – even if it’s only a very small amount. For aerospace and other tight-tolerance applications, it’s important to remove this flash cleanly and in a way that won’t affect part geometry or surface finish.
During the cryogenic deflashing process, molded parts are subjected to very low temperatures so that the flash becomes brittle and easy to break-off. Depending on the specific process, different types of media are used. For example, cryogenic deflashing uses a special cryogenic-grade polycarbonate (PC) media while cryogenic tumble deflashing uses dry ice particles instead. To clean internal dimensions with complex geometries, the media must be small enough access part features.
The PC media that’s used with cryogenic deflashing comes in different lengths and diameters to finish part features without impacting critical surface tolerances. This media maintains its aggression above 0.015” (0.381mm). Cryogenic tumble deflashing is recommended for holes and cavities with smaller dimensions because dry ice won’t become lodged in tiny cavities and require secondary cleaning. That’s because dry ice sublimates, or changes from a solid to a gas with no intermediate liquid phase.
Choose Nitrofreeze® for Deflashing Molded Parts
Both cryogenic deflashing and cryogenic tumble deflashing are less labor-intensive and more consistent than manual deflashing, a form of flash removal where an employee use hand tools to process one part at a time. For precision plastic molders like Tri-Mack, the benefits of working with Nitrofreeze® include our ability to deflash batches of parts to the same exacting standards. With our computer-controlled process, we can also save the right recipe for future batches of the same part.
