What are the types of ceramic foam filters for foundry?

We know that the ceramic foam filters for foundry is a must for filtering and rectifying in the process of metal casting. It is necessary to use foam as a carrier, and use slurry of different components for hanging and firing. So what kinds of foam ceramic filters are there? This article mainly introduces three common filters on the market. They arise because of the different melting points of different metals cast. According to different melting points, we have produced pastes suitable for such metals. After the slurries of different compositions are fired, filters with different hardness and melting points will be produced. From this we produce three filter discs that correspond to different metal castings. They are silicon carbide ceramic filters, zirconia ceramic filters and alumina ceramic filters. We introduce their characteristics separately.

More information about Himor Tech.

Himor Tech has a complete production line of ceramic foam filters for foundry. From foam selection to foam cutting, to preparing slurry, hanging slurry, firing, sampling and packaging, there are special departments responsible for it. Batches that fail the random inspection will be destroyed and then remade. The quality of the filter affects the casting process of the customer, so we have the strictest quality control.

 

In addition, Himor can provide sample service to customers. Customers only need to pay the price of international air freight, Himor will make samples and provide them to customers for testing. After the samples are qualified, the customer decides whether to purchase in large quantities. The factory is located in Jinan, a city in northern China. Welcome customers from all over the world to visit the factory to check the product quality. Or write your request to our sales team via email: [email protected]. We will reply you in time.
