Infiltration equipment company analyzes the technical process of infiltration technology

Infiltration technology is an improvement on the quality of casting products. In the casting process, the presence of micropores leads to the leakage of the sealed medium, increases the wear of the machining tool, and at the same time increases the production cost, making the quality of the product difficult to ensure, and in the use of the product, Lose the function you deserve. The impregnation technology fully infiltrates the impregnating glue (impregnation agent) into the micropores of the workpiece through the vacuum pressure infiltration device, filling the micropore gap, effectively preventing the leakage and corrosion of the workpiece, thereby achieving the purpose of sealing and trapping. The technical process of infiltration technology is now analyzed by the infiltration equipment company for everyone to understand.

Impregnation related:

(1) Place the parts in the infiltration tank.

(2) Vacuum treatment: The vacuum pump is started, the vacuum pressure is above -0.09 MPa, and the air (or water, oil, etc.) in the micropores or cracks of the parts is extracted by vacuum, and the vacuum time is 15 minutes.

(3) Vacuum the glue into the impregnation tank. The amount of glue should be based on the parts in the immersion basket. Remove the vacuum to normal pressure.

(4) If necessary, turn on the compressor and use compressed air to hydraulically press the glue into the micropores or cracks in the part. The compressed air pressure depends on the specific conditions. If there is no special requirement, the compressed air pressure can be 0.8-1.0MPa. Time is 15 minutes. After the impregnation, open the vent valve to relieve pressure.

Always clean the impregnation solution on the surface of the product. After a long time, it will agglomerate on the surface. Infiltration is very effective for the pores in aluminum die castings. We bought a set of equipment in Ningbo, which basically avoids the air leakage in our aluminum die-casting products. Because our products are used in high pressure, You can't leak at all.
