Alloy steel foundry reveals the infiltration technology process for you

Alloy steel foundryAs a method of treating air holes, it is widely used. In the field of hole sealing technology, compared with the wall thickness of 5mm castings, holes with a diameter of less than 0.254mm are called holes. These holes are usually difficult to detect with the naked eye. In the castings of automobile power system and pneumatic hydraulic system, the presence of micropores can cause leakage of the sealing medium, increase the wear of machining tools, and increase production costs, making it difficult to ensure product quality. In the process of using the product, necessary functions will be lost.

Vacuum pressure infiltration equipment is an effective method to solve the above problems. The reliable micropore sealing ability of the penetrant and the effective solution of infiltration castings are widely trusted by the world. It can resist heat, oil and chemical attack. This process can be used for raw materials and machined parts. Will not cause dimensional changes or contamination of castings.

The alloy steel foundry reveals the scope of penetration in the penetration technology process: suitable for the penetration of zinc alloy, copper alloy, aluminum alloy, cast iron parts, cast steel parts and other air leakage and oil leakage. Typical penetrating parts such as engine block, cylinder head, suction manifold, pump, nozzle, pump, valve cover, cast oil pan, chemical oil tank shell, gearbox shell, crankcase, compressor, ABS controller, power Steering gears, automobile wheels, fuel pumps, natural gas control valves, hydraulic valves, cooling pumps, sealed aircraft equipment, electronic equipment covers, air brake parts and various gas instruments, etc. These castings are sealed by injecting micropores with impregnant, and their pressure-bearing capacity reaches the breaking strength of the castings.

Principle of permeation: permeation is also called permeation and permeation. The penetration glue (penetrant) is fully penetrated into the micropores of the workpiece through the vacuum pressure infiltration equipment, filling the micropore gaps, effectively preventing leakage and corrosion of the workpiece, and achieving the purpose of sealing penetration.
