Deburring Nylon & Delrin

Last week, we exhibited at the Eastec 2009 Tradeshow at the Big “E” Fairgrounds in West Springfield, MA. We met many new people who have burr issues with materials ranging from plastics to aerospace alloys. Although many of these people and their companies try to remove burrs while machining; they still find themselves with some sort of burr issue. While a significant portion of these burr issues were with metals; there were two other materials that kept being mentioned. Nylon and Delrin were two materials that had workers seeking a new solution for removing burrs.

Nylon and Delrin were problematic in terms of machining, but also with molding. Many molders had flash issues while molding these two types of materials. While we would all love to use an alternative material and just forget our burr and flash issues; it’s not that simple. Customers’ needs must be met and fulfilled. The bottom line is that they choose the material. Unfortunately, sometimes it’s Nylon or Delrin.

Many of the people we spoke with at the show are using hand deburring and deflashing. They do it because it keeps operations in-house and is relatively cheap. But, they all agree on two things. First, hand deburring lacks consistency across each part that is deburred. Second, although hand deburring is cheap it can be time consuming. It seems that most manufacturers dislike using Nylon and Delrin due to the residual burrs and flash it creates. When this work is done by hand, it is not unusual to see more burrs created.

Do I have a solution for manufacturers with Nylon and Delrin burr and flash issues? Yes, I do. Our company cannot accommodate every single part that comes through the door; due to size and other restrictions. But, we have had a strong track record deburring and deflashing these two materials. There are many advantages to outsourcing deburring and deflashing for materials like Nylon and Delrin. First, burrs and flash will be removed consistently amongst your parts. No gouges or chips in places that render parts unusable. Second, we will run your parts within two days of receipt. Your parts won’t sit in our facility for two weeks before we run them. Third, all those employees doing hand deburring can be re-assigned to other projects. Fourth, with prices per part as low as $0.02 each; how can it not make sense?

Cryogenic Deburring

This press release was released over the internet today. However, I wanted to add it to our blog for all of our customers to see.

Nitrofreeze® Cryogenic Deburring Service Expands

Worcester, MA - December 2, 2008 - The Cryogenic Institute of New England, Inc. is pleased to announce expanded capabilities for the removal of machine burrs from complex machined parts. The process, known as Nitrofreeze® cryogenic deburring service, has been adopted by a wide range of customers in diverse industries including medical devices, aerospace, automotive, and process control, among others. Nitrofreeze® cryogenic deburring service is ideal for today’s advanced materials, including most plastics, composites, organics, polymers and advanced synthetics.

“The adoption of these advanced materials by engineers has expanded the market for associated finishing processes and the company’s Nitrofreeze® cryogenic deburring service has filled this niche”, according to Robin Rhodes, President of the Cryogenic Institute of New England, Inc. The company first offered its cryogenic deburring process in 2003 and it has since become one of its fastest growing product lines.

Many of the parts that benefit from this unique form of burr removal have intricate shapes that are cut or milled on sophisticated CNC machines. They contain critical dimensions and have strict requirements for a blemish free surface finish. The Nitrofreeze® cryogenic deburring process is able to protect the surface finish and critical dimensions of the parts during burr removal because the parts are processed in a cryogenically frozen condition. This not only protects the part, it also promotes the clean removal of the undesired machine burrs when precisely attacked by the systems cryogenic-grade polycarbonate blasting media.

“One of our biggest challenges is that many potential customers in need of machine burr removal solutions, including machinists, manufacturing engineers and quality managers, have not heard of Nitrofreeze® cryogenic deburring,” according to Ryan Taylor, Product Marketing Specialist at Cryogenic Institute of New England, Inc. “This is despite the fact that our cryogenic deburring offers many advantages, including consistent cleaning, repeatable results, and our ability to remove burrs in recessed and blind holes as small as 0.015 inches”, he added.

The company processes parts for customers on a job-shop or service basis. Typical batch sizes range from dozens of individual components to tens and even hundreds of thousand per week. Typical turnaround time is within a few days of receipt and fast turn service for prototype of other rush parts can be accommodated for a small premium charge. The process is environmentally-friendly, clean, fast and cost effective – especially when compared to other alternative deburring processes.
