The Benefits of Cryogenic Deburring for Precision Plastic Parts

Blue,Plastic,Pellets - Cryogenic Deburring

Is creating the perfect part for your company’s next cutting-edge computing product high on your priority list in 2023? You’re in good company. The demand for quality engineered products is expected to continue to skyrocket in light of today’s latest technological advancements, like artificial intelligence. Fortunately, precision plastic fabrication is helping to meet this need.

When you’re going through the precision plastic machining process, though, your part may need a secondary service called cryogenic deburring as well. Cryogenic deburring services are used to remove unwanted burrs in a component that is being machined.

Here’s a rundown of the many benefits of cryogenic deburring for precision plastic parts. Let’s jump in!

Cryogenic Deburring: What Is It?

Cryogenic deburring services involve removing burrs from a component at an extremely low temperature. Burrs are the raised edges or small pieces of material that have been left behind following the plastic part manufacturing process.

To do this, a deburring service provider will place parts’ burred surfaces in a special machine. The surfaces are then cooled to very low temperatures — for instance, tens of degrees Fahrenheit. The temperature must be cold enough for the parts to become brittle. The cooled components are then typically placed in stainless steel baskets. At this point, the parts’ frozen burrs will be subjected to polycarbonate media. This media will remove the burrs.

Cost Benefits

One of the top benefits of cryogenic deburring is that it is extremely cost-effective. It is among the least costly processes available for removing the burrs generated during machining. The process’s low cost can be attributed to the fact that it can do the work of as many as 60 hand workers. Because you don’t have to assign as many workers to this task, you can reduce your deburring costs significantly.


Another reason why cryogenic deburring is that it is highly efficient. The cryogenic deburring process can be completed on tens of thousands of one-gram pieces in a single hour, for example. This process can dramatically boost a company’s production efficiency and, in turn, save manufacturers time.


Yet another reason to choose cryogenic deburring is that it can be utilized on several types of materials. These materials include the following:

  • Liquid crystal polymers
  • Torlon®
  • Viton®
  • Tefzel®
  • Polycarbonate
  • Polypropylene

Cryogenic deburring can additionally be used on nylons and even Teflon. The process generates reliable and repeatable results for a variety of plastics and polymers.

Removing Recessed Burrs

Cryogenic deburring also offers the benefit of removing burrs that have become recessed and are hard to see.

A reputable service provider can reach inside even demanding part geometries to get rid of internal burrs. This means you can be sure that the machined part you receive will be high quality and won’t fail for years to come.

High Precision

Cryogenic deburring’s high precision is another advantage of this process.

When cryogenic deburring is performed, you can expect your part’s surface to feel smooth. This means that the component’s surface performance will exceed your expectations.

Ability to Work on Jobs of All Sizes

When you choose a reputable cryogenic deburring service provider, you can rest assured that they’ll be able to handle your job whether it’s small or large.

A competent service provider has the necessary equipment and manpower to handle high-volume deburring projects. They’ll also be more than willing to perform deburring on small quantities. They’ll do whatever it takes to meet your unique needs.

Protecting Parts’ Integrity

You might be concerned that cryogenic deburring may harm the component you’re trying to create. The opposite is true. Cryogenic deburring can be performed without altering your parts’ aesthetic appeal and integrity.

Cryogenic deburring doesn’t impact a part’s geometry or surface finish. That’s because the passing polycarbonate media used to remove the burrs is non-abrasive. During this process, only the parts’ offensive burrs will be removed. Little or no residue or dust will remain on the components. In addition, your parts’ edges will be maintained. You don’t have to worry about the edges becoming rounded. Likewise, no other material will be inadvertently removed during this process.

For these reasons, deburring provides a clean and safe alternative to tumbling methods. It is also a better option compared with traditional hand or vibratory methods.

Rapid Service

Another reason to choose cryogenic deburring is that this service can be performed relatively quickly. If you’re in a time crunch, a reliable service provider can get this task done while still meeting your deadline.

Additional Benefits

Finally, cryogenic deburring is a process that is computer controlled. For this reason, it is highly accurate and consistent. That means the technique will help with maintaining your part’s geometry and critical tolerances.

Because the process is computer controlled, it also assures both handler and user safety by helping to prevent dangerous situations. For instance, you don’t have to worry about workers being injured if components with burred edges end up chipping off during the operations.
