Advantages Of Die-cast Aluminum

1. Good product quality: high dimensional accuracy of castings, generally equivalent to 6~7 grades, or even up to 4 grades; The surface finish is good, generally equivalent to 5~8 grades; The strength and hardness are higher, and the strength is generally 25~30% higher than that of sand casting, but the elongation is reduced by about 70%; Dimensionally stable and interchangeable; Die-cast aluminum thin-walled complex castings. For example, the minimum wall thickness of current zinc alloy die-cast aluminum parts can reach 0.3mm; aluminum alloy castings can reach 0.5mm; the minimum casting aperture is 0.7mm; and the minimum pitch is 0.75mm.
2. High production efficiency: high machine productivity, for example, domestic JIII.3 horizontal cold-air die-casting aluminum machine can die-cast aluminum 600~700 times in an average of eight hours, and small hot chamber die-casting aluminum machine can die-cast aluminum 3000~7000 times every eight hours on average; Die-cast aluminum type has a long life, a die-cast aluminum type, die-cast aluminum bell alloy, the life can reach hundreds of thousands of times, or even millions of times; Easy to mechanize and automate.
3. Excellent economic effect: due to the accurate size of die-cast aluminum parts, the surface is smooth and other advantages. Generally, it is no longer used directly for mechanical processing, or the processing amount is very small, so it not only improves the utilization rate of metal, but also reduces a large number of processing equipment and working hours; Castings are cheap; Combination die-cast aluminum can be used in other metallic or non-metallic materials. It saves assembly man-hours and metal.
