Miyahara Industries conducts impregnation processing for metal castings and sintered parts. Impregnation processing involves injecting resin into the pores of castings or the gaps in sintered parts, hardening it, and sealing those unwanted holes. We have various usage records, including automotive parts, precision machinery, and electronic and electrical components, as well as general industrial applications. 【Impregnation Processing Achievements (Excerpt)】 ■ Automotive Parts: Engine blocks, cylinder heads ■ Precision Machinery: Hydraulic cylinders, casings ■ Electronic and Electrical Components: LCD TV parts, underwater pump parts ■ General Industrial Applications: Outboard engine parts, general-purpose engine parts ■ Others: Gas appliance parts, air conditioning units, water valve components *For more details, please refer to the external link page or feel free to contact us.

At Mihara Industries, we perform impregnation processing for metal castings and sintered parts. Impregnation processing involves injecting resin into the pores of castings or gaps in sintered parts and curing it to seal off unwanted holes. The impregnation process consists of five steps, starting with an incoming inspection to confirm that the workpiece is free of contaminants such as water and oil, followed by impregnation, draining, cleaning, and curing. After completing all steps, we prepare for shipment while checking for any abnormalities in the workpiece. 【Impregnation Process】 ■ Incoming Inspection and Basket Packing ■ Impregnation Process ■ Draining Process ■ Cleaning Process ■ Curing Process *For more details, please refer to the external link page or feel free to contact us.

Miyahara Industries conducts impregnation treatment processing for metal castings and sintered parts. Impregnation treatment involves injecting resin into the pores of castings or the gaps in sintered parts and curing it to seal those unwanted holes. Our company collaborates with the Central Research Institute to use the organic impregnation agent standard "Super Seal P-601." "Super Seal P-601" is an organic impregnation agent that combines high impregnation effectiveness with excellent durability and cleaning performance. 【Features】 ■ High impregnation effectiveness ■ Excellent durability after impregnation curing ■ Sufficient cleaning effect with just water washing *For more details, please refer to the external link page or feel free to contact us.

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.

At Mihara Industrial Co., Ltd., we perform "impregnation treatment processing" by injecting resin into the voids of castings and the gaps in sintered parts, and curing it to seal unwanted holes. By performing impregnation treatment, we provide airtightness to cast parts and bring various effects as a pre-treatment for plating and painting. 【Effects】 ■ Airtightness - Sealing the voids in parts made of castings to provide airtightness, preventing the leakage of gases and liquids. ■ Pre-treatment for Plating - Preventing the intrusion of plating solution into the fine surface voids, thus preventing blistering and peeling of the plating. ■ Pre-treatment for Painting - By replacing the air and resin in the surface gaps, we prevent blistering during processes like baking paint, and plating is also possible on sintered bodies. *For more details, please download the PDF or feel free to contact us.
