Colored and black metal forgings, in the forging process, easy to produce angry holes, shrinkage holes and loose defects. With these tiny holes, if the thick arms of the arms are connected together, the castings will leak when they are subjected to pressure or hydraulic pressure, causing the product to be scrapped. Infiltration process is an effective method to solve the above setbacks.
Application: Infiltration of leaks, leaks, and leakage of oil, such as aluminum alloys, zinc alloys, copper alloys, cast irons, and steel castings. Typical impregnation castings such as engine heads, cylinder heads, inlet manifolds, oil pumps, grease nipples, water pumps, valve covers, forged oil pans, carburetor housings, transmission housings, cast iron plates, crankcases, Compressors, ABS controllers, power steering gears, automobile wheels, fuel pumps, natural gas control valves, hydraulic valves, filters, cylinders, cylinders, hydraulic pumps, cooling pumps, enclosed aircraft instruments and electronic equipment shields, gas systems Moving parts and various gas meters.
Infiltration related:
(1) Put the parts into the infiltration tank.
(2) Vacuum treatment: start the vacuum pump, the vacuum pressure is above -0.09MPa, and vacuum the air (or water, oil, etc.) in the micro hole or crack of the part, and the vacuum time is 15 minutes.
(3) Use a vacuum to suck the glue into the impregnation tank. The number of glue should be based on the parts in the immersion basket and remove the vacuum to normal pressure.
(4) If necessary, turn on the compressor and use the compressed air to hydraulically press the glue into the micro holes or cracks in the part. The pressure of the compressed air is determined according to the details. If there is no special requirement, the compressed air pressure can be 0.8-1.0 MPa. 15 minutes. After infiltration, open the vent valve to relieve pressure.
Be sure to wash away the impregnation liquid on the surface of the product in time. A long time will agglutinate on the surface. Infiltration is very effective for the air holes in aluminum die castings. We bought a set of equipment for use in Ningbo, which can basically avoid the leakage phenomenon in our aluminum die casting products because our products are used in high pressure applications. Nothing can leak. If the product quality requirements are high, it is still necessary. It is not usually used in high pressure situations, nor is it necessary. As long as you use your brains on a die casting machine, do a good job.
