Immersion is widely used as a method for treating stomata, and in the field of microporous sealing technology, compared to the wall thickness of 5mm castings, we call holes below 0.254mm in diameter as micropores. These holes are usually difficult to detect with the naked eye. In the automotive power system and pneumatic hydraulic system castings, the presence of Micropores will lead to the leaching of sealed media, increase the wear of machining tools, while bringing about increased production costs, so that the quality of products can not be guaranteed.
Will be used in the use of the product, so that it loses its due function. Vacuum pressure infiltration equipment is an effective method to solve the above problems, the immersion agent permanent and reliable parts microporous sealing capacity and effective solution to the leaching castings of this process has been widely trusted worldwide. And can resist heat, oil, chemical erosion. This process can be used on raw materials, machined parts.
Does not cause dimensional changes, or castings are contaminated. Leaching range: Suitable for: Zinc alloy, copper alloy, aluminum alloy, cast iron parts, steel castings and other leakage oil infiltration. Typical leaching parts such as engine cylinder block, cylinder head, intake manifold, oil pump, nozzle, water pump, valve cover, casting oil sump, carburetor shell, gearbox shell, crankcase, compressor, ABS controller, power steering device, automobile hub, fuel pump, natural gas control valve, hydraulic valve, cooling pump, sealed aircraft instrument, And electronic instrument shields, gas brake parts and a variety of gas instrumentation.
These castings are permanently sealed by the immersion agent injected into the microporous, and their pressure capacity reaches the fracture strength of the castings. Infiltration principle: Immersion (impregnation) is also called immersion, penetration. Through the vacuum pressure leaching equipment, the leaching adhesive (leaching agent) is fully infiltrated into the workpiece microporous, filling the microporous gap, effectively preventing the leakage and corrosion of the workpiece, so as to achieve the purpose of sealing leakage.
