What are the advantages of aluminum alloy die casting mould

die casting mould is a casting process completed by pressure. Now it is widely used in all walks of life. die casting mould naturally has incomparable advantages. Some conclusions are summarized for you: 

1. Die castings have high precision, stable scale, good consistency and small machining allowance

2. It can die-casting threads, lines, words, pictures and symbols: the die-casting filling process is always carried out under the pressure effect, and the shapes of peak and valley, convex and concave, narrow groove and so on can be clearly die-casting. Therefore, die casting can press out very clear threads, lines, words, pictures and symbols. 

3. Die castings can be coated with surface treatment: due to the increasing use scale of die castings, in order to meet the needs of use, the surface of die castings can be coated with surface treatment, such as electroplating, anodizing, polishing, organic maintenance coating, painting, sand blasting, acid pickling, etc. Then reach the decorative or maintenance needs. 

4. Using insert casting method in die casting mould can save installation process and simplify manufacturing process: parts with other materials (such as steel, iron, copper, alloy, aluminum, etc.) can be embedded in die casting parts, so as to save valuable data and processing hours, and obtain parts with disordered shapes and parts with excellent functions. 

5. The die castings are arranged in a fine way, with high strength and hardness: due to the rapid cooling of liquid metal in the die. They crystallize under pressure, so a layer of metal near the outer surface on the die casting has fine grains and fine arrangement. Improve the appearance hardness. The tensile strength of die castings can be 25% - 30% higher than that of sand castings, but the elongation decreases. 

6. Die casting production power is very high: zinc aluminum die casting production process is easy to mechanization and automation. Generally, the cold jade chamber die casting machine can die cast 600'i00 times every eight hours, while the hot pressing chamber die casting machine can die cast 3000-two times every eight hours. Because the die-casting process is mainly completed on the die-casting machine, it is easy to automate the production process. 

7. Casting wall is thin and shape. Messy and clear summary: the minimum wall thickness of aluminum alloy die castings can be 0.3mm, the minimum wall thickness of aluminum alloy die castings can be 4.5mm, and the minimum casting hole diameter can be 0.7mm; The minimum pitch of castable thread is 0.75mm.
