Why is the casting infiltrated

Date:11-08-2018

Infiltration is widely used as a method for treating pores. In the field of micropore sealing technology, we refer to pores having a diameter of less than 0.254 mm as micropores with respect to the wall thickness of a 5 mm casting. These holes are usually difficult to find with the naked eye. In the automotive power system and pneumatic hydraulic system castings, the presence of micropores will lead to the leakage of the sealed medium, increase the wear of the machining tool, and at the same time increase the production cost, so that the quality of the product is difficult to be guaranteed. It will lose its proper function during the use of the product.

Stainless Steel Casting Parts is an effective method to solve the above problems. The infiltration agent's permanent and reliable parts micro-hole sealing ability and effective solution to the impregnation casting process have gained worldwide trust. And it can resist heat, oil and chemical erosion. This process can be used on raw materials, machined parts. Does not cause dimensional changes or contamination of the casting.

Impregnation range: suitable for: impregnation of gas leakage and oil leakage of zinc alloy, copper alloy, aluminum alloy, cast iron and steel castings. Typical impregnations such as engine blocks, cylinder heads, intake manifolds, oil pumps, nozzles, water pumps, bonnets, cast sump, carburetor housing, gearbox housing, crankcase, compressor,

ABS controllers, power steering, automotive hubs, fuel pumps, natural gas control valves, hydraulic valves, cooling pumps, sealed aircraft instruments, and electronic instrument covers, air brake parts and various gas meters. These castings are permanently sealed by the infiltrant injection micropores, and their pressure bearing capacity reaches the fracture strength of the casting.

Impregnation principle: impregnation is also called impregnation and infiltration. The impregnating glue (impregnation agent) is fully infiltrated into the micropores of the workpiece by the vacuum pressure infiltration device, and the micropore gap is filled, thereby effectively preventing the leakage and corrosion of the workpiece, thereby achieving the purpose of sealing and trapping.
