Fiberglass filtration mesh is woven with special high-twist & high-strength alkali-free fiberglass yarn and special post-treatment. The maximum temperature resistance can reach 900 ℃.

Production Process

WOVEN FABRIC-Special fiberglass mesh filter is woven by high silica and alkali free fiberglass yarn and woven looms.

HEAT SETTING-After woven process, fabric mesh is needed to be heat setting in order to keep horizontal and vertical.

COAT RESIN-Then white fabric mesh is needed to be coated with special resin, which can make it tough enough, finally, it will become brown.

CUTTING SHAPE-There are two cutting ways in our factory, one is by machine, the other is laser light. Usually, square and rectangle are cut by machine, round, fan-shape and other heteroideus by laser light.

HIGH-TEMP CARBONIZE-This is the most important process. The key points are temperature and time.

Application type

● Filter cloth in roll (white & brown, without/with coating) :It can be fixed in the aluminum liquid flow tank, used for aluminum ingot, aluminum rod, aluminum strip and other continuous casting workshop. 

● Cutting mesh (brown, coated with resin): Square, round, fan and other heteroideus mesh cutted just according to client's requirements. Used for filtering aluminum castings and placed in the gating system.

● Cylinder, cap and other special shapes (brown or black, coated with resin or carbonized): used for low pressure casting, such as aluminum alloy wheels, engine cylinder head and so on.

● Smokeless (black carbonization treatment): no combustion, smokeless, low gas output during the filtration process, for high quality requirements of casting production, such as aluminum alloy piston.

Features and Functions
