ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

With increasing process time, the wax layer blocks the pores of the membranes and gradually decreases the flux rate. Once the oil flow becomes too low, the feed is stopped and air is fed to the center of the membrane, thus blowing off the wax layer from the outer surface of the membrane. After air back-blowing and flushing out the wax that has ...

Protolabs' machining service makes parts from two types of aluminum: 6061-T651 and 7075-T651. The T-suffix signifies how the material was processed, in this case mechanically stretched by 1 to 3 percent after heat treatment to eliminate residual stress, thus making it more stable when machined. 6061 aluminum is alloyed with magnesium and silicon, and in its wrought …

Cleaning Process. We start off with a bare greasy block and put it into our electric oven where it bakes at 800 degrees for 5 hours. Once it comes out of the oven all the grease is turned to ash and it is ready for the blasting process. Our shot blaster shoots stainless steel shot at the block for 45 mins to get the cast iron back to new form.

Pull down on the lever to lower the anvil and bend the aluminum. As the lever goes down, the anvil will descend, pressing the punch pipe into the aluminum at the bend line. This, in turn, will cause the aluminum to conform to the angle of the notch in the V-block. When you're done, simply remove the piece and wipe off the bend line.

Aluminum can melt and fuse to the tool if there's too much heat. So even though it cuts like butter, it won't for long if the aluminum sticks to the tool and you end up doing friction stir welding instead of machining. Beyond keeping friction to a minimum, chatter can be a beast when you're pushing the machine.
