Ferrous and ferrous metal castings, the casting process, easy to produce defects such as porosity, shrinkage, and osteoporosis. These tiny holes, if the arm thick line of defense communication, castings by pneumatic or hydraulic role will form a leak, resulting in product obsolescence. Infiltration technique is an effective way to solve the above problems.
Suitable for: aluminum alloy, zinc alloy, copper alloy, iron castings, steel castings and other steam leakage, infiltration leaks, oil spills. Typical infiltration casting as the engine block, cylinder heads, steam inlet manifold, oil pump, fuel injectors, water pump, valve cover, casting sump, carburetor housing, gearbox housing, cast iron plate, the crankcase compression machine, ABS controller, power steering, car wheels, fuel pump, gas control valves, hydraulic valves, filters, cylinders, cylinder, hydraulic pumps, cooling pumps, sealed aircraft instruments and electronic instrument shroud, air brake parts and various gas meter.
Infiltration relevant:
⑴ parts into the impregnation tank.
(2) vacuum processing: actuated vacuum pump, the vacuum pressure in the above-0.09MPa, vacuum parts within the pores or cracks of air (or water, oil, etc.), extracting, vacuum time of 15 minutes.
(3) using a vacuum to suck the glue into the impregnation tank, the number of glue to the the immersion basket in parts prevail, remove the vacuum to atmospheric pressure.
⑷ If necessary, turn on the compressor, pores or cracks in the plastic hydraulic into parts with compressed air, compressed air pressure according to the specific circumstances may be, if there are no special requirements, compressed air pressure 0.8-1.0MPa can time 15 minutes. Infiltration opened the vent valve relief.
Must be cleansed the product surface Baptist exudate. A long time will agglutinate the surface. Stomatal infiltration for aluminum die casting is very effective, and we bought a set of devices in Ningbo, basically to avoid air leaks in our aluminum die casting products, because our products are used in high-pressure situations, It is also not leak. High product quality requirements, is necessary. Generally not used in high-pressure situations, there is no need, as long as the brains in the die-casting machine, do a good job in a little line.
