With the development of the manufacturing industry, the application of aluminum alloy die castings has become more and more extensive, and higher requirements have been put forward for the surface quality of aluminum alloy parts. So which shot blasting machine is good for cleaning aluminum alloy die castings?
One, we must first understand the difference between aluminum alloy die castings when using shot blasting machines
- Usually the workpiece is not big and the weight is lighter.
- The hardness of the workpiece is low, so reduce the ejection speed and the size of the steel shot.
- The size of the steel shot is reduced, so the air filter of the dust collector should also be reduced.
- Aluminum powder is easy to produce, and aluminum powder is conductive, flammable and explosive dust, so special attention should be paid.
- Second, the choice of the type of shot blasting machine for aluminum alloy die castings.
1, Q37 hook type aluminum alloy Die Casting shot blasting machine.
Q37 hook type aluminum alloy die casting shot blasting machine can clean aluminum alloy die castings in all directions. The equipment is equipped with a spreader device, the workpiece is hung on the spreader, and then the entire spreader is hung on the hook. After entering the shot blasting room, the hook drives the spreader to rotate 360°, and the upper and lower surfaces of all parts can be cleaned at once . Then the hook is moved out of the shot blasting chamber, the workpiece is unloaded, and the cleaning of the aluminum alloy die casting is completed.
2, QWD aluminum alloy die casting mesh belt shot blasting machine.
The QWD aluminum alloy die casting mesh belt shot blasting machine can clean aluminum alloy die castings continuously, with high continuity and good heat dissipation performance. Place the aluminum alloy die castings on the mesh belt, and the forward speed can be adjusted by frequency conversion to enter the shot blasting. In the room, the upper and lower shot blasters are used for shot blasting and cleaning. After leaving the chamber, the workpiece is unloaded to complete the cleaning of aluminum alloy die castings.
