Cryogenic Rubber Bumpers Deflashing Machine

General Introduction Of Cryogenic Deflashing Machine

The NANJING PEGE 'FROZEN SHOT' cryogenic deflashing machine 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.

Give you an example: Our Model PG-120T, with 120L basket capacity, daily (8 hours ) can complete the processing of 400~800kgs, which is equal with 30~80 workers manual job under the same working time, the production efficiency is really fantastic.

Cryogenic deburring technology is by far the most versatile, effective & economic option of deflashing rubber parts, a compact range of timesaving 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 labor costs;

• An environmentally friendly device;

Technical Parameters Of Pege’s Cryogenic Deflashing Machine

Cryogenic Trimming Machines Working Principle

● 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.

There is a fact that the temperature of flash goes down quicker than the main part itself as the flash thickness is much thinner, so the deflashing process start from the embrittle time of flash and stop before the main part get embrittled. During the T2-T1 range, the flash can be done perfectly without damaging the product itself.

Why We Should the Liquid Nitrogen Deburring Machine for Your Trimming Process?

● 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.

Advantages Of Cryogenic Deburring Machine

● 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. That is say, the cost per part is generally well below any alternative technique.

● 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.

Features Of Pege’s Automatic Cryogenic Deburring Machine

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.

● Big size impeller for driving big capacity medias one time;

● Continuous optimization of the inner hexagon structure, to achieve the optimal use of space; Thus, the consumption of liquid nitrogen is reduced and the efficiency is improved;

● High quality NISSEI motor, Mitsubishi controller and PLC;

● User friendly HMI, all parameters can be seen clearly and it is quite easy to operator;

● In-line flash and media separator (3 Layers);

● BASF PIR foam insulation stabilizes ambient temperature;

● Does not require a dryer;

● Long media life (approx. 300 cycles);

● With electrically heated door seal strip.

FAQs On Cryogenic Deflashing Machine

1. What consumables used for cryogenic trimming machine?

The main consumables for nitrogen deflashing machine including the LN2, shot blasting media and Power.

2. How to set the parameters for cryogenic deflashing machine?

Six main parameters, temperature, wheel speed, barrel speed, and processing time, media size and quantity.

Temperature: The cooling temperature to freeze the flashes.

Wheel speed: Decide the power shot on the flashes with media.

Barrel speed: The tumbling speed of the barrel to keep all the parts be blasted.

Processing time: Processing time depends on the processing result and quantity of the parts.

Media size: 0.5 0.75 1.0 1.2 and 1.5mm, each one has different power.

Quantity: The number of parts can be processed.

We always use these 6 parameters to describe the right processing parameter and adjust gradually to find a best one.

3. How to choose the right LN2 container for the nitrogen deburring machine?

■ Choose Cylinder (Volume of 210liter, 250liter or 300liter)-IF ONLY PROCESS ABOUT 4-8HOURS PER WEEK liquid nitrogen big tank will be vaporized regularly if long time not running, so cylinder will be better.

■ Choose Big tank (Volume of 3m3,5M3, 8M3 or 10M3)- If machine runs about 4 hours a day, 3-5 days per week, big tank still be good choice as the Ln2 price is much cheaper and not need to fill the container all the time.
