In recent years, advanced production methods such as the production of rods or pipes directly and continuously (or semi-continuously) from the state of molten metal are being promoted at home and abroad. Domestically, this method has been adopted in copper, copper alloy, aluminum, and aluminum alloy. Artificial graphite is considered to be the most suitable material for continuous casting or semi-continuous casting of non-ferrous metals. Production practice has proved that due to the use of graphite molds, its thermal conductivity is good (thermal conductivity determines the solidification speed of metals or alloys). The self-lubricating properties of the mold and other factors not only increase the speed of the mold, but also because the size of the ingot is accurate, the surface is smooth, the crystal structure is uniform, and the processing in the next process can be directly performed. This not only greatly improves the yield, reduces the loss of waste, but also greatly improves the quality of the product. Continuous casting methods include vertical continuous casting and horizontal continuous casting.
Longdao graphite has been engaged in the processing of graphite products for many years. Graphite molds such as hammer molds, firstly, the mold designers design the mold structure according to the requirements of the products (parts), draw the drawings and then pass the technical workers according to the drawings. All kinds of mechanical processing (such as lathes, planers, milling machines, grinding machines, electric sparks, wire cutting and other equipment) do each part of the mold, and then assemble and debug until a qualified product can be produced.
The processing of modern graphite molds relies more on high-precision, high-efficiency machine tools with a high degree of automation. From graphite die roughing and heat treatment to various finishing quality control and testing, it must be fully equipped and reasonable. Among them, CNC machining equipment accounts for a large proportion to adapt to the production of units or small batch molds. At the same time, CNC machining equipment is also the basis of graphite mold CAD/CAE/CAM, which helps to realize the fully automatic processing of graphite mold manufacturing.
