Matters needing attention in the production of zinc alloy die-casting

Essai Industries Co.,Ltd | Updated: Jun 15, 2017

Zinc Alloy die-casting production process is a fine long production process, slightly careless will give follow-up processing steps left a lot of trouble. The following is a summary of the experience in the process of die-casting production.
1, the control alloy components from the procurement of alloy ingots, alloy ingots must be based on special high purity zinc, coupled with special high-purity aluminum, magnesium, copper alloy ingots made of, the supply plant has strict ingredients standards.
2, high-quality zinc alloy die-casting material is the production of excellent zinc alloy bearing castings guarantee. Buy back alloy ingots to ensure that there is a clean, dry stacking area to avoid prolonged exposure to the wet and white rust, or pollution of the factory dirty to increase the production of slag, but also increase metal loss. A clean factory environment is useful for the effective control of alloy components. Zinc Alloy die-Casting 2
3, the new material and water mouth, such as the proportion of recycled material, not more than 50%, general new material: old material = 70:30. Aluminum and magnesium are gradually reduced in continuous remelting alloys.
4, the water mouth material remelting, must strictly control the remelting temperature should not exceed 420 Shan, in order to avoid the loss of aluminum and magnesium.
5, the condition of the die-casting plant is best to melt zinc alloy melting furnace, so that the alloy ingots and recycled material evenly ratio, the flux can be more effective use, so that the alloy composition and temperature to maintain uniform stability. Electroplating waste, fine crumbs should be a separate furnace.
