Vacuum Impregnation
The Vacuum Impregnation process works to eliminate leaks, improve the quality of products, reduce warranty costs, and reduce costly inspection and test procedures. The procedure is used for sealing micro porosity in metal castings, powder metal parts, electronic components, plastic composites, and other porous substrates.
Anionics operates an anaerobic vacuum impregnation system. The control of variables in the anaerobic process allows us to develop a customized imp spec for each application. Controlling the rate of cure allows us to clean blind holes prior to full cure. This ensures the holes will not be plugged with excess resin. Unlike the Thermal process, parts are not subjected to extreme heat eliminating bleed out of sealant. The self-curing properties of the anaerobic process are not dependent on achieving a specific temperature eliminating the possibility of operator and equipment error.
CASTING IMPREGNATION
The process effectively seals leaks in castings. Castings are impregnated in preparation for finish operations such as plating and painting. Sealing porosity prevents corrosive fluids from entering the casting.
POWDER METAL PARTS IMPREGNATION
The process seals the extensive porosity inherent to PM parts. Prevents absorption of cleaning agents and acids used in plating and painting. "Chatter" and "Binding" are eliminated greatly extending tool life and machining can be done at much higher speeds on an impregnated part. Impregnation prevents fluid and gases from penetrating a part if applied soon after sintering. It enhances adhesive bonding.
