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.

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 is cryogenic liquid label?

Cryogenic liquid labels are special labels designed to withstand extremely low temperatures associated with storing and handling cryogenic liquids such as liquid nitrogen or liquid oxygen. These labels are made of materials that can maintain their adhesive properties and legibility even in cryogenic conditions, ensuring safe identification of the contents of storage containers or equipment.

Is cryogenic freezing related to nitrogen?

Yes, cryogenic freezing often involves the use of liquid nitrogen to reach extremely low temperatures for preserving biological samples or materials. Liquid nitrogen is a common cryogenic agent due to its low boiling point and ability to rapidly cool items.

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...
