Method for conditioning the surface of zinc alloy die casting
The field of zinc alloy die-casting applications is very extensive, and it is also widely used for zinc alloy die-casting coatings. We have a very good effect on the zinc alloy die-casting surface preheated at 200-300 °C. After applying the coating on the surface of the zinc alloy die-casting, along with the evaporation of water, we form a micron-scale film on the surface of the zinc alloy die-casting, which separates the molten metal from the zinc alloy and prevents the molten metal from infiltrating into the zinc alloy die-casting. The surface creates a sticking mold and prevents stamping and entrainment during casting.
The use of zinc alloy die-casting coating can greatly reduce the impact of zinc alloy die-casting and flushing of the cavity surface during high-temperature casting, and improve the service life of zinc alloy die-casting mold. The surface roughness of zinc alloy die-casting greatly affects zinc alloy. The heat preservation performance in the die casting process, by selecting the raw material sand with different particle sizes to prepare the coating, the smoothness of the zinc alloy die casting surface can be adjusted to meet the requirements of the insulation performance in the casting process. We can also adjust the system heat according to the use of different performance coatings. Resistance, control the cooling rate of zinc alloy die-casting, to ensure that its organization and performance meet the requirements.
