CNC Hardware Processing

Casting is one of the common methods in the production of hardware accessories. It pours liquid metal into a specific mold cavity and waits for it to cool and solidify to obtain the required shape of the accessories. Sand casting has a low cost and is suitable for hardware with complex shapes and large sizes, such as the shells of some mechanical parts. Investment casting can produce high-precision accessories with excellent surface quality, and is often used in the manufacture of hardware accessories in fields such as aerospace that require extremely high precision. During the casting process, parameters such as the temperature, composition, and pouring speed of the molten metal must be strictly controlled to ensure the quality of the accessories and avoid defects such as pores and shrinkage.

Forging process

Forging is the use of pressure to cause plastic deformation of metal materials to obtain hardware accessories with certain shapes and properties. Free forging has high flexibility and can forge forgings of various shapes and weights, but the precision is relatively low. It is often used to produce large shaft and rod hardware accessories. Die forging is forging in a die, which has high production efficiency and good precision. It is suitable for mass production of small hardware accessories with complex shapes, such as connecting rods in automobile engines. Forging can make the internal structure of the metal more dense and improve the strength and toughness of hardware accessories.

Stamping process

The stamping process applies pressure to the metal sheet through the die to separate or plastically deform it. It has the advantages of high production efficiency, high dimensional accuracy and high material utilization. In the production of hardware accessories, it is often used to manufacture thin plate parts of various shapes, such as the housing of electronic equipment and gaskets in hardware tools. Continuous stamping can complete multiple processes in one stamping process, further improving production efficiency. However, the design and manufacture of stamping dies require a high level of technology, and the cost of the die is relatively high.

Machining process

Machining includes turning, milling, drilling, grinding and other methods. Turning is used to process rotating hardware accessories, such as shafts and sleeves. The rotating workpiece is cut by a tool to obtain high-precision dimensions and surface finish. Milling can process hardware accessories with complex shapes such as planes, grooves, gears, etc. Drilling is used to process holes on hardware accessories, while grinding is used to obtain higher precision and surface quality requirements, such as high-precision bearings. These machining processes can accurately process hardware accessories according to different design requirements, but the processing speed is relatively slow and the cost is high.
