Medical silicones can be molded into parts such as distal handles for surgical instruments and dental tools. There are many types of silicone rubber, but medical grade silicones need to meet biocompatibility requirements such as USP Class VI or ISO 10993. Then, after they are molded, medical silicone parts need to have a finish that’s […]
Polysulphones (PSU) are a group of high-performance thermoplastics that provide toughness and stability at high temperatures. They are available in medical grades and can withstand repeated cleaning with disinfecting chemicals. With their very low rate of water absorption, medical PSUs can also withstand superheated steam. In addition, these engineering polymers provide excellent resistance to high-energy […]
What’s the difference between dry ice deflashing vs. cryogenic deflashing? Both are used to remove mold flash from plastic or rubber parts. Dry ice deflashing uses compressed air to propel a stream of solid carbon dioxide (dry ice) particles that blast away surface defects. Cryogenic deflashing uses gaseous nitrogen to freeze parts so that mold […]
The cryogenic engine treatment of turbochargers can extend the life and improve the performance of turbo parts made of aluminum, titanium, magnesium, or stainless steel alloys. During this computer-controlled process, the temperature of the turbocharger is gradually reduced to -300° F and then kept at this cryogenic temperature for 24 hours. By promoting the transformation […]
Cryogenic deflashing for plastic parts is an automated batch process that removes mold flash, excess material that affects surface quality and can cause problems with sealing and assembly. During cryogenic deflashing, molded parts are put in a perforated drum, subjected to cryogenic temperatures, and blasted with plastic media. The cryogen, a gaseous nitrogen, embrittles the […]
