Casting Filter is not common product the name, main types are Casting Filter, Aluminum Casting Filter, etc. The main use of casting filter is in metal casting process of special device, mainly used in molten metal before fluid poured into mold molding, filtering out unwanted impurities and solid particles in molten metal fluids.

The presence of casting filters provides quality assurance for cleaner metal fluids and reduces inclusions and porosity, and ultimately improves the quality of final castings.

Casting filters come in many different forms. Such as common mesh casting filter, stainless steel casting filter, aluminum casting filter. However, production of foundry filter or according to specific manufacturing process to determine.

But in general, casting filter is designed to withstand high temperature of molten metal and can be placed smoothly in gating system or gating basin, this is also to facilitate flow of molten metal into mold to shape filter it.

Their filters may offer high filtration efficiency, thermal stability, and durability, contributing to the overall quality and integrity of the castings.

1. Classification of Casting Filter Materials

Casting Filter

Metal materials for casting filters can be classified based on various factors such as their composition, properties, and intended use. Here are some common classifications:

Aluminum-based filters: Aluminum casting filters, as the name implies, must be made of aluminum or aluminum alloy. In fact, think carefully again, aluminum casting filter its use is certainly used to filter molten aluminum or aluminum.

Iron-based filters: Iron metal casting filter, we can compare gourd ladle, must be made of iron or iron alloy, used to filter molten iron or iron alloy. But compared to aluminum, iron resistance to high temperature is bit significant, so iron metal casting filter can withstand high temperature cast iron process, and will not make its filter failure.

Steel filters: Steel casting filters and type casting filters are basically the same. Steel casting filter must also be made of a variety of steel, such as carbon steel, stainless steel, tool steel. So use of steel casting filter is also clear, often used to filter molten steel.

Copper-based filters: The history of copper casting filter is oldest, according to ancient records, copper metal and copper alloy is first metal used. Therefore, copper casting filters made of copper metal and copper alloy are often used in specific applications where copper performance is beneficial. Such as casting of certain bronzes.

Nickel-based filters: Nickel-type filter made of nickel metal or nickel alloy, often because of its corrosion resistance, high temperature resistance, and durability. It is used in high temperature and high pressure environment.

Titanium-based filters: Titanium casting filters are made of titanium or titanium alloy, do not confuse here, titanium casting filter is not used to filter titanium. It is often used to filter molten active metals or alloys. Titanium has highest corrosion resistance compared to nickel and stainless steel, so titanium casting filters are used in applications that require superior corrosion resistance.

Other metal filters: In addition to these more common metal casting filter, there are some not very common other metal or other metal alloy made of other metal casting filter. Such as magnesium, zinc and other alloys. These other metal filters are usually used in certain specific foundry applications.

In general, each metal casting filter has its own advantages and shortcomings. So material selection should be combined with multiple considerations, such as casting temperature, time, metal composition, filtration efficiency and cost factors. Again, choice of foundry filter material depends on requirements of foundry process.

2. Advantages of Casting Filter Materials

Casting Filter

Casting Filter is used in metal Casting process, common types are Casting Filter, Aluminum Casting Filter, etc. The main objective is to filter molten metal fluid, remove internal unwanted impurities, to ensure that final metal appearance more beautiful, better quality. The choice of metal material for casting filters can significantly impact their performance and efficiency.

In following text, you will see some highlights about metal material of casting filter. First of all to say, everyone loves, flowers bloom stainless steel.

Stainless steel features, durability, high temperature resistance, corrosion resistance, easy to clean and maintenance, is the best choice for casting filter materials. In addition to being easy to clean and maintain, it can be reused many times, and filtering efficiency is always top-notch, thus reducing cost of whole filtering process.

Carbon Steel, its strength and heat resistance is also very good. It is possible that cast filters made of carbon steel may be less corrosion resistant than stainless steel and may even require frequent replacement.

But, as we said above, every material has its advantages and disadvantages, and carbon steel has the advantage of being cheap. If the initial investment is not so much money, then carbon steel is absolutely cost-effective material.

Nickel-based foundry filters, such as Inconel’s, are extremely resistant to heat and corrosion. Compared with stainless steel and carbon steel, nickel alloy casting filter is more suitable for high temperature casting, former and other materials are likely to be quickly dissolved.

Zirconium casting filters, in addition to having high strength, heat resistance these more common characteristics, ability to see is chemical inertia. When foundry industry needs quality and defect-free casting process, it is zirconium casting filter’s turn.

Aluminum casting filter also has good heat resistance, but its real trick is its weight. Because aluminum is lightweight metal, some special occasions such as low-pressure casting process, in consideration of both cost and weight, aluminum casting filter came out.

Here, we can easily find that each metal material has unique flash point. But to choose specific metal material, or to look at a variety of factors, such as temperature, pressure or type of casting metal.
