Fiberglass Cap Filter Used For Low Pressure Casting

Fiberglass Cap Filter is woven with special high-twist & high-strength alkali-free fiberglass yarn, coated by special resin, produced by special post-treatment, and carbonized by high temperature.The maximum temperature resistance can reach 900 ℃.

There are two models:

● Normal yellow(brown) color type (without high temperature carbonization)

● Black color type (with high temperature carbonization)

Application: Filtration of molten aluminium.

Widely used in automobile and motorcycle wheels, cylinder pistons, aluminum rods, aluminum materials, aluminum ingots, aluminum plates and precision casting of all types of aluminum alloy casting.

Functions:

● Effectively remove impurities,

● Reduce turbulence and eliminate air bubbles,

● Improving the quality of castings and reducing costs,

● Does not pollute the aluminum liquid,

● Does not affect the chemical properties of the metal,

● Aluminum waste containing the filter mesh, aluminum liquid from sprue and the riser can be directly returned to the furnace for remelting, greatly reducing costs.

Why are Cap Filters so widely used? 

First of all, it is imperative to reduce the waste of resources in the metal industry. It can effectively reduce more than half of the slag, impurities caused by the waste phenomenon. This is also the main reason for the wide use of filters, also the main trend.

Secondly, it can effectively remove non-metallic inclusions in liquid metal, which is also a big use of cap filter. It can significantly improve the casting structure and mechanical properties, so that the casting quality is higher, better quality, reduce the rejection rate, reduce tool wear.

Thirdly, Cap Casting filter is not only used to reduce casting porosity, but also can effectively reduce casting surface defects and increase process yield. It can effectively screen and adsorb small pre-slag, so that the quality of metal castings is better, the performance is better, to create high-quality castings.
