In addition to making motor rotor plate surrounded by other alloy die casting of aluminum alloy die-casting, in Shenzhen. Compared with pure metals, alloy high strength. For example: Shenzhen strength of aluminum alloy containing SI 11% aluminum alloy for twice times more than Shenzhen. Quick cooling alloy fine grain size and strength than a gradual cooling. Casting uniform size (~ 0.01 m m) than the metal mold casting (about 0.5 to 1.0 mm) and sand casting (1.0 m m or more) smaller. Therefore, identical alloy die castings stronger than slow cooling of metal casting, which is better than sand casting, die casting method, is not like other grain refinement of high intensity or accidental modifications of die casting production process planning and die casting die design and manufacturing, casting, castings, clearing and checking content.

There are many other factors casting technology die casting, injection pressure, such as pressure, heaving force, clamping force, ramming speed, internal port speed, scratching, mold temperature, casting temperature, filling time and time pressures. Only select and reconcile these parameters in order to ensure that the number of rapes. Suppression of defects.

1、thin-walled castings, shape. Large, clean cutting Shenzhen, minimum wall thickness of aluminum alloy die castings can be 0.3 m m, Shenzhen aluminum alloy die casting for 4. 5 mm, smallest hole diameter focus 0.7 m m; vote for minimum spacing of thread 0. 75 mm,

2、highly detailed casting, dimensional stability, equal and small

3、 dense castings, high strength and hardness Due to the Quick cooling of liquid metal in a mold. Crystallization pressure and credentials, is similar to the near-surface layer of metal casting is refined and compact grain. Hardness in appearance. Tensile strength than cast alloy sand castings 25%-30%, but landed elongation.

4、 threading dies, lines, text, graphics and tags Mold filling process is always held under pressure, height, presses, narrow grooves and other shapes can be explicitly passed away. Therefore, press moulds, understand threading, lines, text, graphics and tags.

5、 casting methods using device history, you can omit and simplify the manufacturing process Casting can be embedded into other materials (such as steel, iron, copper, aluminum alloy, Shenzhen and other) in order to survive an expensive materials and parts casting processing times and gained excellent shaped parts and performance parts. In many places, when casting skills can also replace some of the embedded components installation process.

6、 die castings can be coated appearance disposal of penalties Foundry applications in order to satisfy the growing demand in the category of use ' w castings can be coated in appearance looks disposal of penalties, such as organic protective coatings, anodizing, polishing, plating, painting, sandblasting, pickling in appearance. Ornament or covering so as to achieve the requirements.

7、 casting subject is high Foundry machines and automation of the production process is easy. Usually jade uniform 8 hour died of cold Chamber die casting machine 600'I00 and hot Chamber die casting machine can be dead for 3000-twice every eight hours. In die casting machine, the casting process it is important to achieve, because it is easier to make the production process automation.
