Impregnation 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 in comparison with the wall thickness of 5 mm castings. These holes are usually hard to find with the naked eye. In the automotive power system and pneumatic hydraulic system castings, the presence of micro-holes will lead to leaching of the sealed medium, increase the wear of the machining tools, and at the same time increase the production cost, making it difficult to ensure the quality of the product. It will lose its proper function during the use of the product.
Vacuum pressure infiltration equipment is an effective method to solve the above-mentioned problems. The permanent and reliable microporous sealing capability of the infiltrant and the effective solution to the leaching of castings have been widely trusted in the world. And can resist heat, oil and chemical attack. This process can be used on raw, machined parts. Does not cause dimensional changes or the casting is contaminated.
Infiltration range: Applicable to: Infiltration of oil leaks from zinc alloys, copper alloys, aluminum alloys, iron castings, steel castings, etc. Typical impregnation parts such as engine blocks, cylinder heads, intake manifolds, oil pumps, grease nipples, water pumps, valve covers, cast oil pans, carburetor housings, gearbox housings, crankcases, compressors, ABS Controllers, Power Steering, Automotive Wheel 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 infiltrant injection into the micropores, and their pressure bearing capacity reaches the fracture strength of the casting.
Impregnation principle: Impregnation is also called impregnation and infiltration. Through the vacuum pressure infiltration equipment, the infiltrated adhesive (impregnant) penetrates into the micro-holes of the workpiece and fills the gaps of the micro-holes, thereby effectively preventing the leakage and corrosion of the workpieces, thereby achieving the purpose of sealing and leaking.
