鑄件為什么要浸滲

     浸滲就作為一種處理氣孔的方法而被廣泛使用，在微孔密封技術領域，相對于5mm鑄件壁厚，我們將直徑在0.254mm以下的孔稱之為微孔。這些孔通常用肉眼是難以發現的。在汽車動力系統及氣動液壓系統鑄件中，微孔的存在將導致被密封介質的浸漏，增加機加工刀具的磨損，同時帶來生產成本的增加，使產品的質量難以得到保證。將在產品的使用過程中，令其喪失應有的功能。 

    真空壓力浸滲設備是解決上述難題行之有效的方法，浸滲劑永久可靠的零件微孔密封能力和有效的解決浸漏鑄件這一工藝方法得到了世界范圍的廣泛信任。并且可抵抗熱、油、化學侵蝕。這種處理過程可以使用在原料、已機加工零件上。不會導致尺寸變化，或是鑄件被污染。 

浸滲范圍：適用于：鋅合金、銅合金、鋁合金、鑄鐵件、鑄鋼件等漏氣漏油的浸滲。典型的浸滲件如發動機缸體、缸蓋、進氣歧管、油泵、油嘴、水泵、閥蓋、鑄造油底殼、化油器殼體、變速箱殼體、曲軸箱、壓縮機、ABS控制器、動力轉向器、汽車輪轂、燃料泵、天然氣控制閥、液壓閥、冷卻泵、密封的飛機儀器、及電子儀器護罩、氣制動零件和各種氣體儀表等。這些鑄件經過浸滲劑注入微孔被永久的密封，其承壓能力達到鑄件的破裂強度。 

    浸滲原理：浸滲（impregnation）又叫含浸、滲透。通過真空壓力浸滲設備將其浸滲膠（浸滲劑）充分滲入工件微孔中，填充微孔間隙，有效的防止了工件的泄漏
 

Infiltration is widely used as a way to deal with pores. In the field of micropore sealing technology, compared with the thickness of 5mm casting wall, we call the hole with diameter below 0.254mm microhole. These holes are usually invisible to the naked eye. In automotive power system and pneumatic hydraulic system castings, the existence of micropores will lead to leakage of sealed media, increase the wear of machining tools, and increase production costs, so that the quality of products is difficult to be guaranteed. In the process of using the product, it will lose its due function.

Vacuum pressure infiltration equipment is an effective way to solve the above problems. The permanent and reliable micropore sealing ability of the infiltration agent and the effective solution to the leaching of castings have been widely trusted worldwide. And can resist heat, oil, chemical erosion. This process can be applied to raw materials and machined parts. It will not lead to size change or casting contamination.

Infiltration range: suitable for: zinc alloy, copper alloy, aluminum alloy, cast iron, cast steel and other leakage leakage infiltration. Typical impregnation parts such as engine cylinder block, cylinder head, intake manifold, oil pump, nozzle, pump, valve cover, casting the oil pan, carburetor, gearbox shell, shell, compressor crankcase, ABS controller, power steering gear, automobile wheel hub, fuel pump, gas control valves, hydraulic valves, cooling pump, seal aircraft instruments, and electronic instruments and shield, and a variety of air brake parts Gas meter, etc. These castings are permanently sealed by the injection of leaching agent into micropores, and their bearing capacity reaches the fracture strength of the casting.

Impregnation principle: impregnation (impregnation), also called leaching, infiltration. Through the vacuum pressure infiltration equipment, the infiltration glue (infiltration agent) is fully penetrated into the micro hole of the workpiece, filling the micro hole gap, effectively prevent the leakage of the workpiece
