In precision manufacturing, burrs are one of the most common and problematic imperfections. These unwanted projections, often formed during machining, can affect a part’s performance, safety, and appearance. For plastic components in particular, traditional deburring methods may damage the part or alter its dimensions. That’s where cryogenic deburring comes in—a clean, accurate, and efficient alternative.

Cryogenic deburring is a process that cools parts to very low temperatures until the burrs become brittle. Once frozen, the burrs are blasted with non-abrasive polycarbonate media inside a controlled chamber. This allows the burrs to be removed cleanly without harming the rest of the part. The result is a smooth, consistent finish that meets tight tolerances.

This method is especially useful for small and intricate plastic components where manual deburring is time-consuming and inconsistent. It’s ideal for removing burrs from materials such as PTFE, nylon, acetal, and PEEK. Since it’s a non-contact, computer-controlled process, cryogenic deburring ensures repeatable results for both small and high-volume ...

Additionally, cryogenic deburring generates no dust, uses no harsh chemicals, and requires minimal post-processing. It’s a safer, more sustainable option for manufacturers looking to improve product quality while minimizing environmental impact.

Whether the goal is to improve part aesthetics, ensure safety, or meet strict quality standards, cryogenic deburring offers a reliable solution. It plays a vital role in industries such as medical devices, aerospace, and fluid power—anywhere precision and performance matter.
