Import Ceramic Foam Filter — Buy in Bulk from Supplier in China

The ceramic foam filter offered by Honstar Industrial Co., Ltd. captures particles as small as 10 microns, providing a lightweight yet durable barrier for molten metal. It is designed for use in aluminium and copper casting operations, where it removes inclusions that can cause casting defects. The filter’s open‑cell structure enables high flow rates while maintaining filtration efficiency. Its construction tolerates the high temperatures typical of foundry processes.

Ceramic foam filters are normally produced from alumina‑based ceramic, a material that offers excellent thermal stability and chemical resistance. Industry practice commonly uses pore densities of 10‑20 pores per inch (PPI) and thicknesses between 10 and 30 mm to balance flow and retention. Such filters can operate up to about 1500 °C, meeting the demands of most non‑ferrous metal melts. Typical compressive strength exceeds 10 MPa, ensuring the filter survives the pressure of pouring operations.

Foundries seeking to improve casting quality and reduce defects are the primary buyers of this product. Honstar states that it can accommodate flexible minimum order quantities and ships under FOB or CIF terms, with efficient packaging designed for safe transport. While the supplier mentions certification to ISO and SGS standards, buyers should request the relevant certificates. Payment and shipping details are arranged directly with the supplier to match the buyer’s logistics requirements.

Honstar Industrial Co., Ltd. is located at 402 Chaoyang Road, Beijing, China. The supplier is placed in the harbor trust tier, indicating that the platform has verified basic business credentials. Response metrics show a 0.00 % response rate and no recorded average response time, which suggests that communication may require proactive follow‑up.

The company lists ceramic foam filters as its core product for foundry applications. Its catalogue highlights the filters’ ability to improve casting quality by removing oxides and inclusions. No additional corporate history, employee numbers or revenue figures are provided in the source data.
