Cryogenic deflashing is a form of deflashing used to remove any excess plastic from parts that are molded. As molds wear and age they develop places where flash can occur. Typical areas for flash are along the part including parting lines and edges. Flash can be removed using various deflashing methods.
Cryogenic deflashing utilizes batch processing to remove flash from parts. If thousands of parts are molded at a time and exhibit flash, then they can be processed quite quickly. Parts are processed in a cryogenic deflashing machine that lowers temperatures and shoots media. The lower temperatures allow the flash to freeze and become heavy. Then media is shot at the parts which takes off the flash. Normal cycles are less than 30 minutes.
Cryogenic deflashing offers repeatable results again and again. The surface of the parts are not destroyed or discolored. The only thing that is removed is the flash. Cryogenic deflashing is great for rubber, silicone, various plastics, and some metals. It is also is a cheaper process due to its speed of execution and lot sizes. I have been working with cryogenic deflashing equipment for several years and I can say that they are one of the most cost-effective ways to deflash any part.

Why cryogenic fluid is superior to any other cooling fluid in powered equipments?
due to the high heat generation in powered equipments there is requirement of maintaining the properties of fluid at high temperature hence cryogenic material have better properties.
Why is a cryogenic engine important?
A cryogenic engine is important because it will carry heavy payloads to geosynchronous transfer orbit. This is highly essential for future telecommunication and space exploration. It is able to carry up to five tons compared to the 1.5-ton payload capacity of PSLVs.
How does cryogenic machining work?
Cryogenic machining means cooling down the cutting tool with liquid carbon dioxide or nitrogen to very low temperatures ( -78,5°C or -109,3°F and below). This enables a clean production process without conventional cutting fluid that is hazardous to both the environment and to health.
How does temperature change E for steels?
Going cold, not very much - it may get a 2% higher at cryogenic temps. Going warn, it does decrease by up to 20% as you get to 1000 degrees F ( from 30 Msi to 24 Msi)
What material type used for cryogenics?
Metals not plastics. What is your goal? For the most part metals with some mixture of carbon see the best results from a cryogenic treatment. However, materials such as aluminum, copper, and other metals have had excellent results as well.
What is cryogenic heat treatment?
cryogenic metal treatment
What are the some example of cryogenic gases?
Any gas that liquifies below -150 degrees C is a cryogenic gas. The most popular cryogenic gas is liquid nitrogen.
What rhymes with photogenic?
cryogenic :)
What is cryogenic freezer?
A cryogenic freezer is used to bring components inside the freezer down to cryogenic temperatures. Many cryogenic freezers are available for all sorts of applications. Cold boxes with added ln2 capabilities can refrigerate parts and then complete cryogenic processing cycles. Additionally, cryo freezers are available to freeze sex cells, stems cells, and more. Sometimes people are frozen after death, which is called cryonics. I have added a site below that has cryogenic freezers and processors available.
What has the author I Spradley written?
I. Spradley has written: 'Integrated Cryogenic Experiment (ICE) microsphere investigation' -- subject(s): Insulation, Microgravity, Microparticles, Weightlessness, Liquid helium, Cryogenic equipment, Cryogenic storage
Was some cryogenic frozen?
cryo-what!?
Is cryogenic freezing related to nitrogen?
Cryogenic freezing is certainly related to nitrogen. In order to complete a deep cryogenic treatment a cryogen must be used. The least expensive cryogen for deep freezing is liquid nitrogen. Another cryogen is helium which allows special made cryogenic processors to reach temperatures approaching absolute zero.
What is rocket cryogenic engines?
Rocket engine
Is xenon used in cryogenic chambers?
Not especially.
Where cryogenic valves are used?
Cryogenic valves facilitate the transfer of Liquified gas. Space industry, natural gas / petroleum, medical industry, chemicals.
Explian about cryogenic hardening?
Cryogenic hardening is often referred to cryogenic treatment and cryogenic processing. Using the term "hardening" is not correct. Cryogenic treatment does not increase the hardness of metals (I.E. rockwell hardness). Rather it changes metals on the molecular level so that they perform better. Cryogenic treatment is used for a variety of reasons including improving dimensional stability, stress relieving, increasing wear resistance, and eliminating walk and creep. A typical cryogenic treatment lasts for several days. Metal and steel parts will be put in a cryogenic processor at room temperature. The temperature will slowly be taken down to -300F below. Then it will hold there for 12 to 24 hours depending on the company doing the treatment. After that, the processor will have the temperature raised back to room temperature very slowly. Finally, the parts will be post-tempered to finalize the cryogenic treatment. Cryogenic treatment re-aligns the micro-structure of the metal to improve its structural stability. Retained austenite will be converted to martensite which allows for a tougher piece of metal. The eta-carbides in the metal will become precipitated which allows for a much higher degree of wear resistance. Below are some good sites for additional reference...
