What types of sandblasting machines are there for mobile phone cases?
Special sandblasting machine for mobile phone case mainly has the following types:
Manual sandblasting machine:
Working mode: The operator holds a spray gun and sandblasts the mobile phone case placed on the workbench. This type of sandblasting machine is relatively simple in structure and flexible in operation, which is suitable for sandblasting of small batches and varieties of mobile phone shells, or for sample making and small-scale production.
Advantages: low equipment cost, small floor space and convenient operation and maintenance. Operators can flexibly adjust the angle, distance and time of sandblasting according to the specific situation of mobile phone cases, and can carry out targeted sandblasting operations on some mobile phone cases with complex shapes and special parts that need fine treatment.
Disadvantages: the work efficiency is relatively low, and the labor intensity is high. The consistency of sandblasting effect may be affected by the technical level and experience of operators.
Automatic conveying sandblasting machine;
Working mode: the mobile phone case is automatically transported to the sandblasting area by the conveyor belt, and the spray gun sandblasts the mobile phone case according to the preset procedures and parameters. After sandblasting is completed, the mobile phone case is transported out of the sandblasting area by the conveyor belt. This kind of sandblasting machine is usually suitable for mass and standardized production of mobile phone cases.
Advantages: high production efficiency, continuous and stable sand blasting operation, and greatly reduced labor intensity. Because the sandblasting process is carried out according to the preset procedure, the sandblasting effect is consistent and the product quality is stable. Moreover, by adjusting the parameters such as the speed of the conveyor belt, the angle of the spray gun and the sandblasting pressure, it can adapt to the sandblasting requirements of mobile phone shells with different materials, shapes and sizes.
Disadvantages: the equipment structure is complex, covering a large area, and the investment cost is relatively high. The maintenance and debugging of equipment need professional technicians, and the technical requirements for operators are also high.
Rotary sandblasting machine:
Working mode: the mobile phone case is placed on the turntable, which is driven by the motor to rotate, and the spray gun is fixed around the sandblasting area to sandblast the mobile phone case rotated to the position of the spray gun. When the turntable rotates once, all parts of the mobile phone case can be sandblasted.
Advantages: multiple mobile phone shells can be sandblasted at the same time, which improves the production efficiency. The rotating speed of the turntable and the sand blasting parameters of the spray gun can be adjusted as required, which is suitable for sand blasting of mobile phone shells of various shapes and sizes. For some mobile phone cases that need omni-directional sandblasting, such as round or spherical mobile phone cases, the rotary sandblasting machine has unique advantages.
Disadvantages: The structure of the equipment is complicated, and the rotating accuracy and stability of the turntable have certain influence on the sand blasting effect. In the process of sandblasting, it is necessary to ensure that the mobile phone case is firmly fixed on the turntable, otherwise the sandblasting effect may be affected.
Drum sandblasting machine:
Working mode: the mobile phone case is put into the drum, and the drum rotates under the drive of the motor. At the same time, the spray gun sprays abrasive into the drum to sandblast the mobile phone case. Drum sandblasting machine is usually suitable for sandblasting small and regular mobile phone shells, such as mobile phone buttons and small mobile phone pendants.
Advantages: a large number of mobile phone cases can be sandblasted in batches, and the production efficiency is high. Because the mobile phone shell is constantly tumbling in the drum, the sandblasting effect is relatively uniform, and all parts of the mobile phone shell can be sandblasted comprehensively.
Disadvantages: For some mobile phone cases with complex shapes and large sizes, the drum sandblasting machine may not be applicable. In the process of sandblasting, there may be collision and friction between mobile phone shells, resulting in scratches or wear on the surface of mobile phone shells.
Liquid sandblasting machine:
Working mode: using water or other liquid as medium, the abrasive and liquid are mixed to form a liquid-solid two-phase flow, which is sprayed on the surface of the mobile phone case by a spray gun for sandblasting. Compared with the traditional dry sandblasting machine, the liquid sandblasting machine will not produce dust flying in the process of sandblasting, and has better environmental protection performance.
Advantages: It is suitable for sandblasting some mobile phone cases with high surface quality and no dust residue, such as mobile phone cases made of optical glass and metal cases of high-end mobile phones. Liquid sandblasting machine can also reduce abrasive consumption and production cost.
Disadvantages: The equipment structure is complex, so it needs to be equipped with special liquid circulation system and abrasive mixing system, and the investment cost is high. Moreover, in the process of use, it is necessary to change the liquid and cleaning equipment regularly, and the maintenance workload is heavy.
