A Guide To Cryogenic Deflashing Equipment

A deflashing Equipment is also known as a deburring machine. This cryogenic deflashing has been in existence for approx. Fifty years and is still used by most the manufacturers. However, it has become popular in recent 15 years, and now every supplier opts for it. This process is done by using liquid nitrogen under high-speed rotation to remove the flash in the most practical and economical manner. 

Cryogenic Deflashing offers a modern method of removing burrs from parts shaped all through the molding process. This process eliminates flash via tumbling and exploding polycarbonate media under a cold atmosphere. Once the flash becomes brittle, it can be easily removed. There are three basic types of burrs, i.e., poison burr, roll-over burr, and tear burr; it solely depends upon the part and application required. 

Cryogenic deflashing equipment is divided into two types, i.e., basket and belt. The basket type is designed to process small parts along with 100% parts containment. The belt style is designed for heavier/ large parts since they require room space to tumble and stronger rotation. 

Cryogenic deflashing is appropriate for parts molded of different materials like polymers, plastics, rubbers, nylons, silicone rubber, neoprene, polyurethane, liquid crystal polymer, ABS, polycarbonate, EPDM, Delrin, acetal, and many others.

Construction

The cryogenic deflashing equipment is constructed with a stainless-steel cabinet and thick polyurethane foam. Inside of a cabinet consists of the blast chamber, throw wheel, and liquid nitrogen nozzle. After this, plastic shots are deployed, which range from 0.15 to 1.4 mm. These plastic parts make sure not to rush or part contamination. Routine maintenance can last any machine for several years and reduce part failure. 

Advantages Of Cryogenic Deflashing Equipment 

A cryogenic deflashing equipment provides various benefits when compared with manual deflashing methods, which are discussed below:

•Greater productivity than traditional deflashing machines; cryogenic trims any part in seconds. 

•Best product quality produces the best possible quality and ensures part integrity. 

•Saves production time more than any other traditional method.

•Cost-effective, produces lower price per piece. 

•Produces consistent/ accurate results from part to part.

•Requires lesser maintenance than any other deflashing method.

•Simplistic and fully automated makes it very easy to use. 

•Requires less labor since it is computer controlled.

•Reduced product waste.

•Improved temperature control.

Cryogenic Deflashing Process

Deflashed and deburred in a flash, the same process is used in the automotive, medical, and electronics industries. The cryogenic deflashing process offers a distinct way for companies to eliminate burrs from parts. A few short steps to do that is as follows:

•Loading parts in the basket later loaded into the deflashing system.

•Pumping gaseous nitrogen into the machine.

•After achieving the required operating temperature, parts begin to tumble with one another.

•After the cycle gets completed, it removes residual from the parts.

•The basket is removed from the system, and the parts are allowed to dry.

Most Cryogenically Deflashed Products In Day-To-Day Life

•Gaskets and O-rings

•Surgical tools

•Medical implants

•Electronic switches and connecters

•Rubber washers or gears

•Plastic fittings

•Grommets

•Valve blocks and manifolds

Conclusion

In this modern era, most molding applications are made via cryogenic deflashing instead of repairing the molds approaching their end life. It is always economical to add a few production costs for a part instead of investing in a new mold that costs hundreds and thousands of dollars. Thus, cryogenic deflashing is recognized as the most advanced technology to ensure high-quality parts with cutting-edge compounds and materials.
