Die-casting molds is a casting process that uses pressure. Now it is widely used in all walks of life. Die-casting molds naturally have its incomparable advantages. I have summarized some for you: 1. The die-casting parts have high precision, stable dimensions, good consistency, and small machining allowance. 2. Can die-cast threads, lines, text, graphics and symbols: the die-casting filling process is always carried out under the effect of pressure. Regarding peaks and valleys, , convex and concave shapes, narrow grooves and other shapes can be clearly die-cast. Therefore, die casting can produce very clear threads, lines, text, images and symbols.
3. Die castings can be coated and surface treated: As the application scope of die castings is expanding day by day, in order to meet the needs of use, the surface of die castings can be coated and surface treated, such as electroplating, anodizing, polishing, and organic protective coating. coating, spray painting, sandblasting, pickling, etc. Then arrive at needs that are decorative or maintenance.
4. Using the inlay casting method in die-casting molds can save the installation process and simplify the manufacturing process: parts of other materials (such as steel, iron, copper, alloy, aluminum, etc.) can be inlaid in die-casting parts to save valuable materials. materials and processing man-hours, and can obtain parts with complex shapes and parts with outstanding functions.
5. The die-casting parts are finely designed and have high strength and hardness: because the liquid metal cools quickly in the die. At the same time, it crystallizes under pressure, so the metal grains in the layer of metal close to the surface on the die casting are finer and densely organized. Improve surface hardness. The tensile strength of die castings can be 25%-30% greater than that of sand castings. However, the elongation is reduced.
6. Die-casting production efficiency is very high: the zinc-aluminum die-casting production process is easy to mechanize and automate. Generally, a cold chamber die-casting machine can perform an average of 600-200 die-casting operations every eight hours, while a hot-pressure chamber die-casting machine can perform an average of 3,000-TWO die-casting operations every eight hours. Since the die-casting process is mainly completed on the die-casting machine, it is easy to automate the production process.
7. The castings have thin walls and poor shape. Complex and clear outline: the minimum wall thickness of aluminum alloy die-casting parts can be 0.3mm, the minimum wall thickness of aluminum alloy die-casting parts can be 4.5mm, the minimum casting hole diameter can be 0.7mm; the minimum pitch of castable threads can be 0.75mm.
