The definition of die-casting process

Pressure casting is special casting method in modern metal processing technology developed rapidly in a few non-cutting. It is the process of molten metal at high speed under high pressure mold filling, solidification and formed at high pressure castings. High voltage high speed is the main characteristic pressure casting. Commonly used pressure of dozens MPa, filling speed (ingate speed) is about 16 to 80 m / sec, the molten metal filling the mold cavity a very short time, about 0.01 to 0.2 seconds.
Since this method of producing products with high production efficiency, simple process, high casting tolerance level, good surface roughness, high mechanical strength, can save a lot of machining processes and equipment, conservation of raw materials, etc., so now become in China's foundry industry is an important part.

Die-casting process is the three elements of die casting machine, die casting mold and alloy composition and be organically integrated use in the process. The die-cast metal pressing process to fill the cavity, and is the pressure, speed, temperature and time and other process factors to obtain a uniform process. At the same time, these technical factors and influence each other, mutual restraint, and complement each other. Proper selection and adjustment of these factors make it coherent, in order to obtain the desired results. Therefore, in the die-casting process not only pay attention to the process of casting structure, die-casting mold progressiveness, die-casting machine performance and excellent resistance structure, die-casting alloy smelting process chosen adaptability and normative; more should pay attention to the pressure, temperature and time and other parameters important role in casting quality. In the die-casting process should focus on effective control of these parameters.

Machining is a process that accurate to remove material by mechanical machining technology.

The main classification:
Mechanical processing have manual processing and CNC machining two types. Manual processing is means machining various materials by mechanical workers manual milling machine, lathe, drilling machine and the sawing machine and other mechanical equipment. Manual processing is suitable for small batch production, simple parts. Numerical control machining (CNC) means the mechanical workers use numerical control equipment, the CNC equipment including CNC center, milling center, wire cutting equipment, thread cutting machine, etc. The vast majority of the machining shop machining the parts by numerical control machining technology. Through programming, coordinates the parts in the Cartesian coordinate system (X, Y, Z) into a programming language, the CNC controller of numerical control machine by identifying and explain programming language to control the axis of CNC machine tools, automatic removal of material, get the part according to the requirement and finish machining. CNC machining in a way that is straight artifacts, suitable for mass and complex shape parts.

Step of working out process regulations:

1) Calculating annual production program, determine the type of manufacture.

2) Analysis part drawing and the product assembly drawing.

3) Select blank.

4) Formulation process route.

5) Determine the machining allowance of each process, calculating the dimension and tolerance.

6) Identify the equipment used in each process and cutting tool, jig, measuring tools and auxiliary tools.

7) Determine the cutting dosage and man-hour quota.

8) Determine the main process of technical requirements and test methods.

9) Fill in the process documents.
