    Why choose us:                                                                                                                               

     

    Thanks to the deep and close relationships to our customers of hundreds of rubber manufactures, who are constantly exploring technology for gains in productivity;

    we strongly witness the important of deflashing/deburring, a very important area for cost and quality controlling;

    Thus the reason we add our new series line of Cryogenic Deflashing Machines;

    We target to provide our customers one-stop solutions no matter of small,modest or large scales of production;

     

    Cryogenics is by far the most versatile, effective & economic option of deflashing rubber parts, a compact range of time-saving and quality enhancing deflashing machines.

    • A multi-material deflashing solution providing complete processing flexibility from one machine;

    • A quality enhancing method of deflashing;

    • A system which increases productivity due to its exceptionally fast running speed;

    • An automated cost-cutting method which dramatically decreases operational and labour costs;

    • An environmentally-friendly facility;

     

     

    Advantages:                                                                                                                                    

     

    • Cryogenic deflashing provides various advantages over manual deflashing and  other traditional deflashing methods.
    • The process maintains part integrity and critical tolerances.
    • Since it is a batch process, the price per piece is far less as many more parts can be processed in a given amount of time.Cryogenic deflashing extends mold life.
    • Rather than replace or repair a mold (which typically involves downtime and high cost), the parts can be deflashed. This is typical of parts molded at the end of their product lifetime.
    • The process is computer controlled, therefore removing the human operator variable from the process.
    • The process offers consistent results from lot to lot.
    • Cryogenic deflashing is non-abrasive.
    • The cost per part is generally well below any alternative technique.

    A typical cryogenic deflashing machine consists of a stainless steel cabinet insulated with dense

    polyurethane foam;. Located inside the cabinet are the blast chamber, the liquid nitrogen nozzle, and

    the opening for the throw wheel.

    Why should I use the Freeze Trim / Cryogenic Deflashing trimming machines?           

     

    Deflashing machine also known as deburring machine.

    Though this cryogenic deflashing technology is in existence for over 50 years, its practical introduction happened about 20 years back. Its popularity is on the rise in last 15 years.

    This process uses liquid nitrogen, high-speed rotation and media (shot blast) in varying combinations

    to remove the flash in a highly precise, economical and practical manner.

     

    Compared to manual deflashing and other traditional deflashing methods.

    The fully automated process significantly decreases deflashing time, increasing production capacity

    It also offers complete flexibility to multi-material processors.

     

     

     

    When should I use the Freeze Trim / Cryogenic Deflashing trimming machines          

     

    The INTER-CHINA Freeze Trim provides the user with complete processing flexibility, and it is ideal

    for those with large volume production, multiple part sizes and complexities (including those up to 250mm dia.), different materials, or when a high quality and pristine finish is paramount;

     

    Example: Our Model SD-M/MT, with 120L basket capacity, daily ( 8 hours ) can complete the processing of 400~800kgs, which is equal with 30~100 workers manual job under the same working time.

    It’s a totally amazing productivity.

     

     

    How does the Freeze Trim / Cryogenic Deflashing trimming machines work ;                

     

    Moulded parts are placed into a perforated stainless steel parts basket and then inserted into the blast chamber of the Freeze Trim and the basket is mechanically rotated to expose all parts to the blast media. Liquid nitrogen lowers the temperature (some cases up to -140°C) while freezing the rubber to make it brittle. Because the burrs have a high surface area relative to their mass, they“freeze”very quickly and become brittle.

     

    The physical properties of the parts are not affected during the deflashing process.

    A unique high speed impeller (up to 8,000rpm )directs and throws the polycarbonate media into the rotating basket and by travelling at high speed, the small pellets cleanly trim off the brittle flash leaving a high quality, flash less moulding.

    The tumbling action— combined with the impact of the media— removes the burrs without damaging

    the part itself.

    After the process is complete, parts are returned to room temperature.

    This cryogenic deburring leaves a clean part—with no dust or other residue remaining —with 100%

    burr removal.

    Parts that have thin flash can be quickly and thoroughly cryogenic deflashed. Cryogenic

    Deflashing process is exceptionally good at removing the inner dimensional and complex flash in

    your products that cannot be removed by any other method.

    Temperature fluctuation in operation                                                                                          

    Owing to the fact that the temperature of flash goes down quicker than the mold itself, deflashing can be done perfectly without damaging the product itself.
