        Key production factors of v casting equipment

        The key point of production of v casting equipment is to select the vacuum pumping system. When selecting the vacuum pumping system, the capacity of the vacuum pump should be determined first, mainly considering the following factors:

        1. Size and quantity of sand boxes that need to work in vacuum at the same time.

        2. The number of casting molds to be poured at the same time.

        3. Size and shape of pouring.

        4. The air permeability of the casting surface close to the film, which controls the amount of air entering the mould through the cracks in the plastic film, makes it necessary to use a small amount of casting paint when pouring, which helps to provide an "auxiliary sealing layer" for the vacuum machine.
