What are the zinc alloy die castings?

The temperature of zinc alloy die-casting must be within a reasonable range to produce high-quality products. If the heating temperature is too high or the holding time at high temperature is too long, it will cause the austenite grains to be coarsened and called overheating. This will lead to a decrease in the strong resistance of steel, an increase in brittleness change temperature, and the tendency of deformation and cracking during quenching to be added. The cause of overheating is that the furnace temperature is out of control or mixing. Zinc alloy die casting is a precision casting method that uses high pressure to force the molten metal into a metal mold with complex shapes. It is a precision casting method. Nowadays, zinc alloy die-casting molds are used more and more widely, and they have good mechanical functions and wear resistance at room temperature. Appearance treatment can be carried out: electroplating, spraying. Low melting point, melting at 385°C, easy to die-casting. When melting and die-casting, it does not absorb iron, does not corrode the pressure, and does not stick to the mold. Zinc alloy die-casting Good casting function, capable of die-casting messy-shaped, thin-walled precision parts, and the castings have a smooth appearance. Zinc alloy has a strong three-dimensional effect, and the surface will have graininess or wrinkles after die-casting, and it needs to be polished. Polishing cannot completely change the physical form. JunQi Hardware Co., Ltd. is a company that specializes in the production of luggage accessories.
