FAQ - Cryogenic Removal Of Burrs & Flashing
What Is Cryogenic Deburring & Deflashing?
Cryogenic deburring & deflashing is the process by which excess material on plastic or rubber parts is removed using a combination of extreme low temperature and inert impact materials introduced at high velocity to knock off burrs and flashing while leaving the original form intact.
How Does The Process Work.
Parts to be deburred or deflashed are placed in batches in a rotating stainless steel basket, which is spun at a pre-designated speed inside a specially designed insulated chamber.
How Is Quality Controlled?
High quality and uniform finish throughout a batch and between batches, relies on the proper setting and monitoring of the variables involved:
What Advantages Are There To Using Cryogenics For Removal Of Burrs & Flash?
In general cryogenics as a process produces a consistent, uniformly higher-quality, finished product faster and with less expense then by hand-finishing. In addition, cryogenics is able to remove burrs and flash from internal holes, cross-holes, blind holes, small slots and crevices and other areas that would be either difficult or impossible to do manually.
More reliable, repeatable and consistent results than hand finishing.
Uniform quality throughout a batch and between seperately run batches.
Reduced scrap due to handling and human error.
The ability to remove unwanted material from areas difficult or impossible to remove by hand.
What Benefits Can I Get From Using This Process?
As a client you can expect:
Lower cost as compared to hand finishing.
Uniform quality with little to no rejects.
Same day turnaround in most cases.
Pick up and delivery service for local customers.
Drop shipment service.

Is The Process Safe?
Because the process uses a non-abrasive plastic media it does not alter the shape or geometry of the piece. Careful monitoring of the process results in no alteration of part design or functionality.
