One of our service offerings, cryogenic deflashing has seen a major spike in orders lately. Many customers with silicone and rubber parts are utilizing cryogenic deflashing to clean any excess flash from their parts. For the past twenty five years cryogenic deflashing has been the most efficient way to remove flash from rubber and silicone parts. This form of deflashing can save manufacturers a significant amount of money over hand deflashing.
There are two types of cryogenic deflashing available today. The original method involves a large barrel spinning around. This form is called cryogenic tumble deflashing. The barrel is filled with the parts then cooled to cryogenic temperatures and tumbled. This form of cryogenic deflashing is good for smaller parts with excess flash on the edges. As the parts are tumbled at such low temperatures the flash flakes and rubs off of the parts. Smaller rubber and silicone gaskets are also suitable for this process. We offer cryogenic tumble deflashing in house and have for many years.
The second form of cryogenic deflashing utilizes a media to spray the parts. This process was introduced several years after cryogenic tumble deflashing. We refer to this form simply as cryogenic deflashing. Parts are inserted in to a basket which is then put into the machine. This process is computer controlled and capable of saving recipes for each particular part that is run. Variables that are computer controlled include time, temperature, throw wheel speed (rate at which media is blasted), and basket rpm. Other variables include amount of parts in the basket and the media size used on the parts. This process is more efficient than tumble deflashing for many kinds of parts. Parts with parting line flash, gate flash, ejector pin flash, and flash within cross holes and slots will be removed with this process. This form of deflashing is more effective because cycle times are shorter due the extra media blasting capability. As a result, we are able to save you more money when deflashing your parts. This particular cryogenic deflashing service has become one of our most successful service offerings.
Cryogenic deflashing offers an efficient means to remove flash from your parts. Turnaround time is typically two days after receipt which means fewer delays. Process times are often twenty minutes or less, allowing significant cost-savings. If your parts have very exquisite geometries and a fixture is required, we can design and build one. For those utilizing cryogenic deflashing in house within their manufacturing process, now is the time to outsource especially with fluctuating manufacturing orders. Think about all that wasted money spent on unused liquid nitrogen. Shipping costs are much less than the money wasted on lost liquid nitrogen.
