Cryogenic high-speed shot blast deflashing
Cryogenic deflashing is a process for removing flash from molded rubber parts. We use liquid nitrogen, high-speed rotation and shot blasted plastic media in varying combinations to remove the flash in a highly precise, economical and expedient manner.
Parts that have thin flash can be quickly and thoroughly cryogenically deflashed. This process is exceptionally good at removing the inner dimensional and complex flash that cannot be removed by any other method.

Product Description
PROCESSING PRINCIPLE
With the decrease of the temperature, rubber/plastic parts enters into hardened, brittle, and crystallized process, its flexibility is gradually lost. It is easily broken by external force when it is under brittle temperature. Flash of the molded products is generally much thinner than finished product itself, it become brittle earlier than product in the low temperature. Cryogenic deflashing machine applies this principle, works in the time range when flash is brittle while products still keeps its flexibility, hit the flashes by high speed projected special plastic media, clear out the brittle burr. The flashes can be easily removed and the product not be damaged.
Product Feature
Function
Our machine is widely used in removing the flashed of small rubber and plastic parts like Orings, gaslets and other molded parts.
With the cryogenic processing technology, the flashes are firstly freezed and then shoted down the high speed projection media(Ploycarbonate blast). The surface quality of molded rubber and plastic rubber parts can be impoved greatly.

Application / Models
APPLICATIONS
A. O rings, irregular rubber parts with different material and sizes.
B. Micro electronic product parts
C. Precision elastomeric parts
D. Precision injection moulding plastic parts
E. R & D part runs
F. Die casting products, like zinc aluminum, magnesium alloy
Main benifits
High efficiency: The machine can replace about 60-80 worker to removing the flashes.
High precision: It can remove small and hiddened falshes which cannnot be removed by handworkers and improve precision of the products.
Low cost: It also has a feature of lower cost comparing with processing the parts by handworkers.
