Different products, the selected sandblasting abrasive is also different, let’s talk about sandblasting processing: sand blasting processing range: hardware rust removal, aluminum alloy sandblasting, glass sandblasting (matte effect), plastic sandblasting (deburring), acrylic sandblasting (matte effect), PC, PS surface treatment, resin surface treatment, casting workpiece sandblasting, zinc alloy sandblasting (rough surface), stainless steel material sandblasting, stone material sandblasting, hardware paint removal, hardware welding scar removal, shot blasting, and other accessories surface treatment acrylic sandblasting: if the customer’s requirements are very foggy, generally spray glass sand, if the requirements are higher, you can choose white corundum.
1. The angle of sandblasting processing
Many people believe that holding a blast gun at 90 degrees to work on the work surface will optimize the process of rust or decontamination of the workpiece surface. However, this actually slows down the blasting process and makes the media (sand) wear out faster. Your blast gun should be pointed at a 30-45 degree angle to the surface of the position you want to handle. Especially when you want to find an effect that suits your desire, through multiple angles of work testing, find the balance you need, make a record, and then create your best spray surface according to this standard.
2. Sandblasting processing distance
When sandblasting, closer to the surface of your part does not lead to better results, and it also wastes sand. This is because the working distance reduces the size of the blast area, increases cycle time, and makes it easier to crush the sand, reducing its life. The idea is somewhere in between, giving you the best balance between the rate and rate of sand wear. Hand-controlled suction jet system, six to eight inches. When using a direct injection system for pressure, you should be 10 to 14 inches away. Also keep in mind that the closer you get to thin parts, the easier it is to deform them, no matter what sandblasting sand you use. In addition to finding a suitable distance, avoid deformation of the sandblasting part.3. Sandblasting processed sand
This secret to optimizing the life of your sand, as well as your blasting, is to use the proportion of sand used. Using too much sand won’t get any faster work, and your sand will wear out much faster. Using too little will reduce your efficiency, and it will be difficult to achieve the effect you want, and the amount of sand should be between 50% and 90% of the storage device. Determine your blasting time to meet your requirements, too long is waste. Choose the right sand material to complete the job according to the effect you want and the material of your workpiece, and find the right position angle.
