Why use die casting for parts that can be CNC machined?

 

In the part manufacturing process, in some cases, it is necessary to use die casting methods instead of CNC machining. Although CNC machining can achieve high precision and variety of production, in some respects, die casting has superior characteristics .

 

High production efficiency

 

Die casting is a mass production technique suitable for the production of large quantities of parts. In contrast, CNC machining is usually a small batch production technology that requires processing on a case-by-case basis, with relatively high time and labor costs. Therefore, when producing large quantities of parts, the use of die casting technology can improve production efficiency and reduce costs.

 

Low manufacturing cost

 

Compared to CNC machining, die casting technology can produce a large number of parts in a short time, which can recover equipment investment more quickly and reduce the production cost of each part.

 

Parts with complex shapes can be manufactured

 

Die casting technology can make parts with more complex shapes, such as thin-walled structures, bumps, holes, etc., which are difficult to complete with CNC machining. In addition, die casting can also achieve the production of internal cavities, such as pipes and pipe fittings.

 

 

Wide selection of materials

 

Die casting can be applied to a variety of materials, including aluminum alloy, zinc alloy, magnesium alloy, copper alloy, etc., and can produce high-strength, lightweight parts. CNC machining is limited by the hardness and shape of the material, and is not suitable for processing too brittle or too soft materials.

 

 

The surface quality of the parts is good

 

Because die casting is a closed production technology, the surface of the manufactured parts is flat, and there is no need for secondary processing after forming; CNC machining, on the other hand, requires surface treatment and polishing after processing, which consumes time and labor costs.

 

 

In short, although CNC machining can produce high-precision and a variety of styles of parts, die casting technology has superior characteristics and advantages in mass production, low manufacturing costs, the manufacture of complex shapes of parts, a wide range of materials to choose from, and the surface quality of parts. Therefore, in some cases, the use of die casting technology instead of CNC machining can better meet production needs and improve production efficiency.
