Impregnation treatment: Impregnation method

We will introduce various impregnation methods such as vacuum, liquid filling, pressurization, and curing!

At Mihara Industries, we perform impregnation processing for metal castings and sintered parts. Impregnation processing involves injecting resin into the pores of castings or the gaps in sintered parts and curing it to seal those unwanted holes. There are various impregnation methods, such as the "vacuum" method, which takes a long vacuum time to evaporate moisture inside the pores, and the "liquid filling" method, which utilizes pressure differences in the tank to inject the impregnation agent. 【Impregnation Methods】 ■ Vacuum - By removing air from the tank, air inside the pores of the impregnated material is also removed. - This is a preparatory stage to ensure that the impregnation agent penetrates deep into the pores. ■ Liquid Filling - Utilizing pressure differences in the tank to inject the impregnation agent. ■ Pressurization and Curing - Applying pressure in the tank to introduce the impregnation agent deep into the pores. - Washing away excess impregnation agent on the surface and heating it to cure only the impregnation agent inside the pores. *For more details, please refer to the external link page or feel free to contact us.
