In the processing industry and prototype proofing, sandblasting is a very common surface treatment process, such as: silica gel mold sandblasting to remove mold knife lines, rust removal, and rust prevention; plastic mold factories to do fine etching; oxidation plants after sandblasting Oxidation (to make the whole workpiece more beautiful and durable); plastic sandblasting in the prototype factory to quickly remove burrs, remove paint, remove tool marks from hand milling, etc. But in fact, many people don't know how to choose sandblasting in the surface treatment of the prototype. So the following is a brief introduction for everyone by the Xiehe prototype processing factory.

Sandblasting 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, Sand blasting of casting workpieces, zinc alloy sand blasting (rough surface), stainless steel material sand blasting, stone material sand blasting, hardware paint removal, hardware welding scar removal, shot blasting, and other accessories surface treatment.

Acrylic sandblasting: If the customer requires very foggy, glass sand is generally sprayed. If the requirement is higher, white corundum can be used. If it is not very foggy and has a certain degree of transparency, glass beads must be used. Sometimes a little glass sand is added to the glass beads, so that the sprayed effect is a little bit transparent.

Stainless steel sandblasting: Generally, you need to know what kind of panel stainless steel is. There are polished alloy steel shot, brushed surface, and the matte surface of the original plate. If roughness is required, and there is no requirement for surface smoothness, brown corundum and white Corundum has special requirements, and glass beads and glass sand are used for smoothness.

Die-casting parts: Generally, low-alloy steel is used to remove burrs. Generally, shot blasting machines can be used for low-alloy steel. Shallow and small, steel grit is used to remove thick surface dirt, and steel balls and steel grit can generally be used in combination. If you want to make the sandblasted aluminum parts whiter, you should consider using high-cost stainless steel shots and steel wire cut shots. If you want to save costs, consider mixing cast steel balls and endless steel shots at a ratio of 8:2. When shot blasting, the steel balls are cleaned once every time they work, and the whiter effect can be achieved by sandblasting and shot blasting several times.

The above content is the selection of sandblasting in the surface treatment of the prototype, and I hope it can be helpful to everyone. If you want to know more about the prototype, please call the Xiehe prototype manufacturer, we will serve you wholeheartedly.
