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
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；
- 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
A wide range of molded materials can utilize cryogenic deflashing
with proven results. These include:
- Plastics – (both thermoset & thermoplastic)
- Rubbers – (including neoprene & urethane)
- Liquid crystal polymer (LCP)
- Glass-filled nylons
- Metal deburring
- Zinc and aluminium castings
Examples of applications that use cryogenic deflashing include:
- O-rings & gaskets
- Catheters and other in-vitro medical
- Insulators and other electric / electronic components
- Valve stems, washers and fittings
- Tubes and flexible boots
- Face masks & goggles
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
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
Compared to manual deflashing and other traditional deflashing
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
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
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
This cryogenic deburring leaves a clean part—with no dust or other
residue remaining —with 100%
Parts that have thin flash can be quickly and thoroughly 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.
