Advantages of low pressure casting machine

2022-08-15

The advantages of low pressure casting machine are shown in the following aspects:

1. The pouring process parameters of low-pressure casting can be set and adjusted arbitrarily within the process range. The low-pressure casting machine can ensure the smooth filling of liquid metal, reduce or avoid the agitation, impact and splash of molten metal during filling, thereby reducing forming. Oxidation Slag, prevent or reduce casting defects, improve casting quality.

2. The molten metal is filled under pressure, which can improve the fluidity of the molten metal, and the casting has good formability, resulting in a clear contour of the casting and a smooth surface of the casting. It is more conducive to the formation of large thin-walled castings.

3. The casting crystallizes and solidifies under the action of pressure, which can be fully fed, the casting structure is compact, and the mechanical properties are high.

4. The process yield of molten metal is improved, generally no riser is needed, so the yield of molten metal is greatly improved, generally up to 90 percent.

5. The working conditions are good, the production efficiency is high, and it is easy to realize mechanization. Automation is also a prominent advantage of low-pressure die-casting.

6. The range of low-pressure casting alloys is wide, and it can basically be used for various casting alloys. It is not only used for casting non-ferrous alloys, but also for cast iron and cast steel. Especially for easily oxidized non-ferrous alloys, it shows its superior performance, that is, it can Effectively prevent molten metal from producing oxidized slag during pouring.

7. Low-pressure die-casting has no special requirements for mold materials. All kinds of materials that can be used as molds can be used as mold materials for low-pressure casting. It is basically the same as the mold used for gravity casting and special casting, such as sand mold (clay sand, water glass sand, resin Sand, etc.), shell mold, metal mold, graphite mold, investment casting shell mold, ceramic mold, etc. In short, low pressure casting has no strict restrictions on casting materials.
