Production of zinc alloy badge, process performance zinc alloy signs

To make high-quality zinc alloy die-casting products, we must first understand the performance of the production process zinc alloy, zinc alloy material has its own unique special properties, it is usually in the production of high-grade badges, signs, nameplates and other complex technology products, must be used zinc alloy die-casting process. Chen Yu handicraft factory Cangnan with superb zinc alloy die-casting production process, and solid strength. Affordable zinc alloy plate, high-quality zinc alloy badge, in the peer industry has a unique advantage, in order to go on with our common prosperity, we have to continue to innovate in the future, strive to meet our customer requirements.Zinc alloy is a zinc-based alloy adding other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloy. Zinc alloy low melting point, good fluidity, easy to welding, brazing and plastic processing, corrosion in the atmosphere, disability facilitate recycling and remelting material; however, low creep strength, prone to dimensional changes caused by natural aging. Preparation of melting, casting or pressure processing to become useful. According to the manufacturing process can be divided into cast zinc alloy and zinc alloy deformation.????The main element of zinc alloy with aluminum, copper and magnesium. Zinc alloy by deformation processing can be divided into two categories with cast zinc alloy. Cast zinc alloy fluidity and good corrosion resistance, suitable for die-casting instrumentation, automotive parts case Wait.First, the characteristics of the zinc alloy1. The relatively high specific gravity.2. casting performance, or complex die-cast shapes, thin wall precision castings, smooth surface.3. can be surface treatment: electroplating, painting, painting, polishing and grinding.The melting and do not smoke when iron-casting, pressure-type non-corrosive, non-stick mold.5. Have a good room temperature mechanical properties and wear resistance.6. The low melting point, melting at 385 ℃, easy casting.Use process issues to be aware of:1. poor corrosion resistance. When the alloy composition of impurity elements such as lead, cadmium, tin than the standard time, resulting in deformation of casting aging, expressed as a volume swell, mechanical properties, especially ductility decreased significantly, a long time or even rupture. Lead, tin, cadmium zinc alloys solubility is very small, and therefore focused on the grain boundaries become the cathode, aluminum-rich solid solution of an anode, in water vapor (electrolyte) presence of conditions to foster intergranular electrochemical corrosion. Casting due to intergranular corrosion and aging.
