Die casting molds are casting processes that use pressure to complete, and are now widely used in various industries. Die casting molds naturally have incomparable advantages, and we have summarized some for everyone:
1. Die castings have high precision, stable scale, good consistency, and very small machining allowance.
2. Capable of die-casting threads, lines, text, drawings, and symbols: The die-casting filling process is always carried out under pressure, and shapes such as peaks, valleys, and narrow grooves can be clearly die-casting. Therefore, die casting can produce very clear threads, lines, text, drawings, and symbols.
3. Die castings can be coated for surface treatment: Due to the increasing scale of use of die castings, in order to meet the needs of use, the surface of die castings can be coated for surface treatment, such as electroplating, anodizing, polishing, organic maintenance coating, painting, sandblasting, acid pickling, etc. Then reach the demand for decoration or maintenance.
4. The use of inlay casting method in die-casting molds can save installation process and simplify production process: parts with other materials (such as steel, iron, copper, alloy, aluminum, etc.) can be embedded in die-casting parts to save valuable information and processing time, and can obtain parts with disorderly shapes and outstanding functions.
5. The arrangement of die-casting parts is fine, with high strength and hardness: due to the rapid cooling of liquid metal in the die. Together, they crystallize under pressure, so the layer of metal grains near the outer surface on the die casting is finer and arranged more densely. Improve the surface hardness. The tensile strength of die castings can be 25% -30% higher than that of sand castings, but the elongation is slightly reduced.
6. The die-casting production power is very high: the zinc aluminum die-casting production process is easy to mechanization and automation. Usually, the cold jade chamber die-casting machine can cast 600'I00 times every eight hours uniformly, while the hot pressing chamber die-casting machine can cast 3000-TWO times every eight hours uniformly. Due to the fact that the die-casting process is mainly completed on the die-casting machine, it is easy to automate the production process.
7. The casting has a thin wall and shape. Chaotic and clear summary: The minimum wall thickness of aluminum alloy die castings can be 0.3mm, while aluminum alloy die castings can be 4.5mm, the minimum diameter of the cast hole can be 0.7mm, and the minimum pitch of the thread that can be cast is 0.75mm.
