Aluminum Castings Corporation’s Sand Mold Department
The Sand Mold Department at Aluminum Castings Corporation consists of automated molding, Roto-lift, squeezer, and an air set line with our new Kloster air set molding machine. High quality aluminum casting sand molds, with the dimensional characteristics and surface finish that you require, begin with closely monitored sand controls. Our computer controlled sand preparation and distribution system maintains proper moisture and consistency of our molding sand using in-line digital sensors.
Air set or No Bake Sand Molding Process
Aluminum Castings Corporation’s Air Set, sometimes called No Bake,sand mold making process uses a dry sand and a fast curing chemical mixture to produce the aluminum casting molds. In this process the patterns are filled with the air set sand mixture and compressed, making the cope and drag of the expendable aluminum casting sand mold. The air set process allows for tighter dimensional accuracy and also offers better surface finishes. These aluminum casting molds can also be internally cored using our shell sand cores, cold box sand cores, and oil sand cores from our Sand Core Department. to produce highly complex aluminum castings. Aluminum Castings Corporation can meet your large aluminum casting needs!
Green Sand Molding Process
In our green sand molding process the patterns to make our sand molds are filled with the wet sand mixture, which is bonded by clay, and compressed making the cope and drag of the expendable aluminum casting sand mold. This sand mold can then be sent to our Aluminum Melting & Casting Department and cast or it can also be internally cored using our shell sand cores, cold box sand cores, and oil sand cores from our Sand Core Department.
For larger production runs we have installed a new mold handling system. With this system the sand molds are created and put onto a conveyor system. The molds are then moved to the pour station where they are poured and the freshly poured sand molds then move down the line until they are cool enough to be dumped onto our shaker systems which shakes the sand off of the aluminum casting. This system eliminates much of the manual labor which once was involved with moving the castings from station to station, etc which allows us to be more productive and safer when producing our high quality aluminum sand castings.
