The filter bases used in traditional fuel vehicles are made of cast iron, which cannot be recycled or decomposed, further exacerbating the increasingly severe environmental pollution. As the global commercial vehicle market continues to increase, new aluminum alloy materials are needed to replace existing plastic materials. The service life is much longer than that of plastic materials, and the cost of recycling and reusing is low, which will naturally reduce the pollution of non-recyclable plastics to the environment.

There is a risk of shrinkage holes in the large circle of the product on the traditional die-casting mold. The failure to accurately control the pressure of the die-casting process can easily lead to air entanglement, poor product forming, shrinkage holes, etc., resulting in a series of quality instabilities.
