The selection of sandblasting materials varies for different products, and the selected sandblasting abrasives are also different. Let's talk about sandblasting: sandblasting scope: hardware rust removal, aluminum alloy sandblasting, glass sandblasting (matte effect), plastic sandblasting (deburring), acrylic sandblasting (matte effect), PC and 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 parts welding scar removal, shot blasting, and other accessory surface treatment. Acrylic sandblasting: If the customer requires a lot of fog, glass sandblasting is generally used. If the requirements are higher, white corundum sand can be used. So how to improve the effectiveness of sandblasting and reduce the wear of white corundum abrasive?

1. Selection of Sand Materials for Sandblasting Processing

Different products have different choices of sandblasting abrasives. Let's talk about sandblasting: sandblasting scope: hardware rust removal, aluminum alloy sandblasting, glass sandblasting (matte effect), plastic sandblasting (deburring), acrylic sandblasting (matte effect), PC and 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 parts welding scar removal, shot blasting, and other accessory surface treatment. Acrylic sandblasting: If the customer requires a lot of fog, glass sandblasting is generally used. If the requirements are higher, white corundum can be used.

Material: Processing purpose \ Selected sand material

Stainless steel: surface cleaning, welding slag removal, and matte effect glass beads/diamond sand

Glass products crystal: frosted, patterned white corundum, brown corundum

Iron workpieces: rust removal, dirt removal, deoxygenation skin removal, increased coating and adhesion, diamond sand added with rust inhibitor

Copper workpiece: Deoxidized matte effect glass beads

Aluminum workpiece: de oxidized skin, surface strengthening, and light decoration effect glass bead diamond sand

Electronic components: clean and remove burrs, surface paint layer, aluminum oxide

2. Angle of sandblasting processing

Many people believe that holding a sandblasting gun at 90 degrees will optimize the process of rust or dirt removal on the workpiece surface for work surface operations. However, this actually slows down the sandblasting process and causes faster wear of the media (sand material). Your sandblasting gun should be directed at a 30-45 degree angle towards the surface of the area you want to treat, allowing your abrasive to achieve good results with minimal wear. Especially when you want to find a suitable effect for yourself, through multiple angles of work testing, find the balance point you need, make a record, and then create your best spray surface according to this standard.

3. Sandblasting distance

When sandblasting, being closer to the machining surface of your parts does not bring better results, and it also wastes sand material. This is because the working distance reduces the size of the sandblasting operation area, increases the cycle time, and makes it easier to crush the sand material, reducing its lifespan. This idea is somewhere in between, achieving a perfect balance between your sand material wear rate and rate. Hand controlled suction and spray system, ranging from six to eight inches. When using a direct injection system, you should be 10 to 14 inches away. Also, please remember that the closer you are to thin parts, the easier it is to deform them, regardless of what sandblasting material you use. In addition to finding a suitable distance, avoid deformation of the sandblasting area.

4. Sand material for sandblasting processing

This secret optimizes the service life of your sand material and also optimizes your sandblasting effect by using the proportion of sand material usage. Using too much sand material will not result in any faster work, but your sand material will wear out much faster. Using too little will reduce your efficiency and it will be difficult to achieve the desired effect. The amount of sand material should be between 50% and 90% of the storage device. Determine your sandblasting time to meet your requirements. If it is too long, it will be a waste. Choose the appropriate sand material based on the desired effect and the material of your workpiece to complete this task, and find the appropriate position and angle.

How to achieve the best surface treatment effect

Determine the high-efficiency method suitable for you based on the material and shape of the workpiece, such as drum rolling operation, 360 degree rotating sandblasting operation, flat conveyor sandblasting operation, etc. The best surface finish for you depends partly on the sand material you use. In fact, mixing different sand materials in proportion may bring different effects, such as making your workpiece surface brighter and saving sand materials. For surfaces with harder materials, we should use harder sand to impact them. If plastic particles are used to impact the surface of steel castings, it is equivalent to hitting stones with eggs. Of course, these are not excellent. Sometimes, according to the desired effect, we must use some opposite methods to obtain them.
