Cryogenic Treatment for Brake Rotors & Pads

noreply@blogger.com (Ryan Taylor) — Wed, 31 Dec 2008 17:06:00 +0000

At the Cryogenic Institute of New England, Inc. we process many brake rotors for cryogenic treatment. We cryo treat brake rotors and pads for recreational customers, but for the most part we do this service for commercial customers.

At the present, we cryo treat brakes for two ambulance fleets in Massachusetts. After speaking with the mechanics at both facilities, they have come to the conclusion that cryogenic treatment works on brake rotors very well. On average, they see 100% to 250% more longer life out of their brakes. This also greatly reduces their overhead costs because the brakes do not need to be changed as often as stock brakes. But, there are other reasons to cryo treat your brake rotors and pads.

Paul Deskins of Systems for Public Safety Inc. recently conducted a test between cryo treated and non-cryo treated brakes. Paul Deskins’ company builds and maintains Police Cars and Fire Trucks in Washington State. After the test, he found that the stopping distance when “hot” was 50 feet shorter with cryo treated brake rotors. As a result, he came to the conclusion that cryo treated brake rotors will prevent accidents. Paul’s testimonial can be seen below.

Purchasing a set of brakes and then having them cryo treated will result in shorter stopping distances in emergency situations. You will also save money because your brakes will last longer and you will not have to pay your mechanic several hundred dollars in labor for brake replacement. Cryogenic treatment on brakes also results in significantly less brake fade. Therefore, your brakes will offer consistent and predictable braking until they need to be replaced; if they ever need to be.

Paul Deskins' Testimonial:

Hi Robin,

I own a Company in Washington State that builds and maintains Police Cars/Fire Trucks. We recently did a brake test on several brake rotors on Police cars. I took one OEM set and had them Cryo treated and they out performed every rotor in the test-Fade and stopping distance. The officers took the data from the test to the City Admin staff and showed that if the fleet was fitted with Cryo brakes it would prevent accidents. The stopping distance “hot” was almost 50 Feet shorter than the rest!

Thanks,

How To Keep That Crankshaft From Breaking, Period

noreply@blogger.com (Ryan Taylor) — Mon, 22 Dec 2008 19:38:00 +0000

This year we cryo treated many crankshafts to help our customers. These customers had recently purchased crankshafts to help assure that they would not fail like their original ones did. After seeing so many crankshafts, it makes you wonder why they fail. After a little research, it became apparent why they fail. The two main reasons can be found below.

The Wrong Crankshaft: A stock crankshaft is made for a car that is left in its stock state. When a racer decides to add more torque and horsepower to their application, they put more stress on the stock crankshaft. Some stock crankshafts can handle some added power, but most cannot. There are many ways to solve this problem. One is to purchase a stronger crankshaft that is made to deal with the extra stress of higher horsepower and torque. Another is to take the stock or aftermarket crankshaft and cryo treat it to remove residual internal stresses that can contribute to crank failure. Other alternatives include the application of surface coatings.
Flawed Vibration Dampers: Stock dampers tend to have moving parts. For example, some crankshaft dampers have hydraulic oil in them. As the crankshaft rotates the fluid in the damper causes inertia. The end result is more stress on the crankshaft, which in time will lead to crank failure. Many aftermarket crankshaft manufacturers have found that lighter and smaller vibration dampers are better for racing applications. A small solid piece of rubber as a vibration damper is much better than one filled with hydraulic oil, because it will not cause inertia.

The bottom line is if you are going to add a ton of power to your engine, then you should expect a failure of your original stock crankshaft at some point. The way to ensure that a failure does not happen is to purchase a stronger crank or have your OEM or aftermarket crankshaft cryogenically treated. At the same time, if you are increasing power you should look for an aftermarket vibration damper that does not cause extra stress on the crankshaft.

Cryogenic Deburring

noreply@blogger.com (Ryan Taylor) — Tue, 02 Dec 2008 16:53:00 +0000

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.

More information is available at the company’s web page http://www.nitrofreeze.com/deburring.html.

Dry Ice Blasting Industrial Equipment

noreply@blogger.com (Ryan Taylor) — Tue, 11 Nov 2008 18:02:00 +0000

Dry Ice Blast Cleaning also known as dry ice blasting and co2 blasting has been one of our service offerings for the past two years. We have completed many jobs involving industrial equipment, fire damage, and mold remediation. Dry ice blasting is a very different yet environmentally friendly cleaning process.

Unlike sand blasting and pressure washing, dry ice blasting is approved by the FDA, EPA, and USDA. Why does that matter some may ask? The answer is simple, it allows us to clean food processing lines and equipment along with other medical applications.

Sand blasting leaves sand and grit all over the area to be cleaned; pressure washing leaves a slippery wet mess on the floor. These two cleaning processes cannot be used on every application for the cited reasons. Dry ice blasting doesn't leave anything on the floor except the grit from the surface that was cleaned. The dry ice (aka co2) that we use comes in pellet form. This means that it is about the size of a tic-tac. As the operator uses the dry ice blasting equipment, dry ice is blasted at the surface and evaporates as it cleans the surface. Therefore, there is no wet mess on the floor.

The most important principle that differentiates dry ice blasting from sand blasting and pressure washing is the fact that dry ice blasting is non-abrasive. Picture a brick wall that was painted white. Sand blasting it would take off the paint, destroy some of the grout, and damage the surface finish to the bricks. Pressure washing may take off some of the paint, but probably not all and don't forget the gallons of water all over the floor. Dry ice blasting will remove the paint, but keep the grout and surface finish to the bricks just the way it was before the bricks were painted.

Dry ice blasting can be used on different surfaces including metal, brick, wood, stone, and many others. The picture above shows our president helping us clean the Telegram & Gazette's main printing press located in Worcester, MA. Our company offers dry ice blasting throughout the whole New England area. For more information take a look here at http://www.nitrofreeze.com/dry_ice_blast_cleaning.html.

Cryogenic Treatment for Racing and Automotive Parts

noreply@blogger.com (Ryan Taylor) — Tue, 04 Nov 2008 19:58:00 +0000

In the recent weeks, I have seen a jump in interest regarding cryogenic treatment for automotive parts. Many of these customers have a lot of questions, and we are more than happy to answer them.

Cryogenic treatment works on many different racing components. But many ask why would one want to have their parts cryogenically treated? There are several different reasons. Your parts will last longer. The residual stresses in the material will be relieved, which will result in a more uniform grain structure. This reduces the chance of failure within your part. The parts will also have a higher resistance to wear. Take a look at this article published in Race Engine Technology magazine, http://www.nitrofreeze.com/RETP3034Cryo.pdf.

I can tell you that we have treated many crankshafts, transmission gear sets, pistons with rings, and connecting rods this year. There are many other applications for the racing industry, that can be seen here, http://www.nitrofreeze.com/racing.html. There are other parts we can cryogenically treat as well, just call and we will be glad to help.

DieBlast Cryogenic Deflashing & Deburring Media Won't Work For Us

noreply@blogger.com (Ryan Taylor) — Wed, 27 Aug 2008 14:01:00 +0000

The last blog post I made was about the introduction of DieBlast Cryogenic Grade Polycarbonate Media into our facility. We were able to try a sample of both the .020 and .060 media.

Our first sample was a current part that we already run for one of our present customers using the .020 media. We split the order into three batches. One was using our current Maxi-Blast media for the original cycle time of ten minutes. Out of a set of 230 parts, 26 parts were rejected. This means that 12% out of 230 parts needed to be run a second time. You would think 12% was high but then we ran the DieBlast media.

When we were offered a sample of DieBlast, we were told that it reduces cycle times, and cycle rpms, as well as liquid nitrogen intake. No matter what we would not change the temperatures of our recipes. So the only way liquid nitrogen intake would be reduced is by shorter cycle times. We ran the same rpm for the throw wheel and a seven minute cycle instead of a ten minute. Out of 230 parts, 55 parts were rejected. So 24% out of 230 parts needed more time to remove all the burrs. Then we ran our third lot which was identical to the original recipe besides the fact that it was using DieBlast media. Out of 230 parts, 44 were rejected. 19% of 230 parts needed a longer cycle time.

Needless to say, I was surprised by the results and expected DieBlast to do a lot better. It failed to meet our expectations. Therefore, we will continue to use Maxi-Blast and Polyblast media that we have always used. Their media is very similar in shape and lifetime.

DieBlast Cryogenic Grade Polycarbonate Deflashing & Deburring Media

noreply@blogger.com (Ryan Taylor) — Fri, 22 Aug 2008 15:17:00 +0000

After a few weeks of waiting our new cryogenic grade media arrived for our cryogenic deflashing and deburring operations.

For the time being, we get to try samples of both .020 and .060 media by Dieblast. Dieblast is currently made in the United Kingdom. The media is different from it's competitors Maxiblast and Polyblast because the media is in a cube shape versus drum shape.

As a result, the media has 16 cutting edges versus 2 on the current media we have been using. The photo shows two piles of the Dieblast media. The .060 is on the left and the .020 is on the right. Next to both those piles are a sample of the current media we have been using.

Unfortunately, we haven't actually been able to run a sample using the Dieblast media yet. But, once we run a few samples with it, I will report back and post our results using this new type of media.

Electromagnetic Deburring Sample Success

noreply@blogger.com (Ryan Taylor) — Wed, 06 Aug 2008 14:32:00 +0000

The manufacturer of the electromagnetic deburring machine just ran some samples for us. Our contact there was very happy with the results. There was only one part out of the sample that wasn't fit for this deburring process. He was able to get all the holes and edges using the different kinds of media on the many parts we sent him. Run times were between 20 and 40 minutes, so we should be able to keep costs down. Large volumes will help with the longer cycle times to help keep price down as well. After a few more samples, if we continue to get positive results, we will be bringing this technology in house.

Adding Better Metal Deburring & Surface Polishing Capabilities

noreply@blogger.com (Ryan Taylor) — Fri, 01 Aug 2008 15:36:00 +0000

Over time, we have realized that metal deburring is part of our business. Some metal products however do not get their burrs removed through our cryogenic deburring process. In the past few months, we have been researching an affordable machine capable of better serving our customers with metal and steel products for deburring.

One machine in particular that may fit our needs uses an electromagnetic current to excite a stainless steel media that removes burrs from both ferrous and non-ferrous metal. We are currently working with the machine manufacturer to have samples run by them. After we are assured that the machine is a good fit for us, we may be purchasing one in either September or October.

In the past year, we have realized the need for metal surface polishing as well. The beauty of this electromagnetic deburring machine is that it can be used for surface polishing as well. So, if the machine works for us, we will be able to deburr small metal parts. We will also be able to leave a clean finish for our customers' parts.

If you would like samples run by us, give us a call today at 800-739-7949. Our team would be more than happy to assist you with any of your deburring or surface polishing needs.

New Media for our Deflashing & Deburring Process

noreply@blogger.com (Ryan Taylor) — Fri, 01 Aug 2008 15:18:00 +0000

Recently, we were approached by US Abrasives to try a new type of cryogenic grade media. The media is made by Dieblast in the United Kingdom. For years we have been using Maxi-Blast media. Maxi-Blast media is circular in shape like a drum with only two cutting edges. Dieblast media is in the form of a cube and has 16 cutting surfaces. This should have a major effect on our cryogenic deflashing and deburring operation.

From what we have learned, Dieblast allows you to run at lower rpms, warmer temperatures, and shorter cycles. This means that our liquid nitrogen costs may be reduced along with our energy costs. The media is also supposed to last longer so we should be able to reduce our media consumption costs. If in fact the media works well, pricing for new customers may be able to be reduced due to shorter cycle times. Using this Dieblast media could be a win-win situation for us and our customers.

However, it isn't here yet. We are receiving two fifty-five pound samples next week in both .020 and .060 media. Once, we have ran a few samples using the new media, I will post an update. I hope for it to be a success.

Cryogenic Helium Processing

noreply@blogger.com (Ryan Taylor) — Fri, 01 Aug 2008 15:10:00 +0000

This is a press release that was made about a month ago. However, I wanted to add it to our blog, so that other people can see it.

Cryogenic Helium Processing Approaches New Levels of Affordability

Worcester, MA – June 30, 2008 – The Cryogenic Institute of New England, Inc. introduces a new capability of utilizing liquid helium for cryogenic treatment of materials to temperatures as low as 4K /-268C/-451F. Measurements were recorded by attaching a spring loaded silicone diode cryogenic temperature sensor rated to 1.4K with a calibrated accuracy of +/- 10mK.

The procedure involves the utilization of a specially modified cryogenic chamber that was designed and constructed in collaboration with technology partner Applied Cryogenics Inc. The chamber utilizes multiple dedicated delivery systems for introduction of both liquid nitrogen and liquid helium. The system also utilizes an advanced insulation scheme that involves a combination of sophisticated polyisoanurate materials, as well as vacuum and liquid nitrogen jackets for maximum effectiveness. A proprietary method for controlling the delivery of the helium to the chamber enables controlled rates of temperature change.

According to Robin Rhodes, President of Cryogenic Institute of New England, Inc., the capability grew from the needs of its aerospace customers who sought extreme temperature cycling for residual stress relief of critical components. “It was a natural extension for us to push beyond the limits of liquid nitrogen (77K/-196C/-320F), where we work every day, into the coldest cryogens available”, Rhodes stated. The company reported that they have delivered controlled cryogenic treatment profiles at temperatures ranging from 16K to 4K (-257C/-430F to -268C/-451F) over a dozen times in the past year. The temperatures and profiles were specified by the firm’s customers, who Rhodes declined to identify because of confidentiality agreements.

While the majority of applications have been related to aerospace, the firm has also offered the capability to researchers and other industries, including electronics. Cost for the treatment varies, depending on ramp and soak times, but Rhodes estimates that his firm can offer a near absolute zero treatment cycle (to 4K) for less than 30% of the cost of similar processing as offered through governmental and other research organizations. “We feel that we have a real price breakthrough that will lead to further commercialization of ultra deep cryogenic treatments for residual stress relief and other transformations in materials”, Mr. Rhodes stated.

The Cryogenic Institute of New England, Inc., located at 90 Ellsworth St. Worcester, MA, is dedicated to the commercial application of cryogenic technologies to serve the needs of industry, government and scientists. The firm offers a full range of cryogenic services, including conventional cryogenic treatment, heat & freeze thermal cycling, cryogenic deflashing & deburring services, shrink fitting services, and dry ice (CO2) blast cleaning.
