Introduction to sand blasting process of low pressure mould:

Low-pressure casting mould refers to the industrial technical standard mould compared with the high pressure (gravity gold) casting mould subdivision, the industrial technical mould can be traced back to the field mainly used in the aluminum alloy industry industrialization can be traced back to modern times. At present, low pressure casting mold is mostly used in automobile related parts, such as automobile cylinder head, cylinder block, brake hub, clutch cover, wheel hub, intake manifold. The low pressure casting mold is a non-standard design mold. The characteristics of high material utilization rate in industrial field can greatly reduce the production cost.

Sand blaster manufacturers produce and operate low-pressure casting moulds by placing the moulds on a closed furnace with a tube (called a riser) underneath the cavity and a liquid metal in the furnace. If pressurized air is added to the metal level in the furnace, the metal will flow from the riser into the cavity. After solidification of the liquid metal, the compressed air in the furnace is released, and the unsolidified metal flows back to the furnace from the riser. Control the air pressure and speed into the furnace, control the speed and pressure of the metal into the cavity, so that the metal under the pressure of crystallization and solidification. The process is characterized by the casting crystallization under pressure, compact structure and good mechanical properties. The low-pressure casting is directly connected with the furnace by the riser pipe. The casting is directly cast under the action of pressure, and the outlet is small.

Sand blasting technology introduction:

Sand blasting technology is a process of cleaning and coarsening the surface of matrix by the impact of high speed sand flow. Using compressed air as the power, the formation of high speed injection beam, the injection material (quartz sand, emery, iron sand, glass sand, etc.) high speed jet to need to deal with surface of workpiece, sand blasting equipment to change the look of the surface and shape, the impact on the workpiece surface grinding materials and cutting, surface sandblasting machine makes a certain cleanness and roughness of workpiece surface, Improve the mechanical properties of the surface of the workpiece, improve the fatigue resistance of the workpiece, increase the adhesion between the coating, prolong the durability of the coating, is conducive to the flow and decoration of the coating.
