Cryogenic Deflashing Machine PG-80T

Cryogenic Deflashing Machine Model PG-80T

Cryogenic deflashing machines are known for its precise quality de-flashed parts with up to 95% performance output without affecting the final part dimension and shape from small O-rings to big molded parts.
These Machines serve the need for Rubber, Metal-Rubber parts, small precision plastic parts and small die-casting parts like Zinc and Magnesium alloy.

• Single person operation
• Expertly deflashes parts using cryogenic freezing
• Separates the sprue and/or waste material from the finished parts
• Exceptionally fast and automated and safe, improving operational efficiency
• Provides a pristine quality finish

Working principle of rubber cryogenic deflashing machine

With the decrease of the temperature, rubber/plastic parts enter 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 is not damaged.

Functions of rubber cryogenic deflashing machine 

Our rubber cryogenic deflashing machine is widely used in removing the flashed of small rubber and plastic parts like O-rings, gaskets and other molded parts.

With the cryogenic processing technology, the flashes are firstly freeze and then shot down the high-speed projection media (Polycarbonate blast). The surface quality of molded rubber and plastic rubber parts can be improved greatly.

Applications of rubber cryogenic deflashing machine 

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

FAQs on cryogenic deflashing machine or the technology

1. How does cryogenic de-burring process work?

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.

2.  What is main composition of a cryogenic deflashing machine?

A typical cryogenic deflashing machine consists of a stainless-steel cabinet insulated with dense polyurethane foam. Located inside the cabinet are the blast motor, the liquid nitrogen nozzle, and the opening for the throw wheel. Under the chamber there is a vibrator for separation. And electrical controls including inverter, PLC, relays to control the blasting motor and gear motor. Besides, a barrel with a gear box to swing or tumbling is also important for nitrogen deflashing.

3.  What are main benefits of cryogenic deburring?

■High efficiency: The machine can replace about 60-80 worker to removing the flashes.

■High precision: It can remove small and hardened flashes which cannot 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.

■Constant process result comparing with manual deflashing’s unstable trimming result
