Despite its advantages, die casting aluminum does pose certain challenges. The initial cost for making high-quality dies can be high, which may not be practical for low-volume production. Furthermore, defects such as porosity, which affects the mechanical properties and appearance of the castings, must be managed through careful control of the manufacturing process.

4. Mold Removal Once the material has solidified, the mold is removed. This step may involve mechanical shaking, heating, or even chemical processes, depending on the type of mold used.

Lead is a versatile metal with several properties that make it suitable for sand casting. It is highly malleable, allowing it to easily fill complex mold cavities and produce detailed components. Its density provides excellent weight to parts, making it essential for applications where balance and mass are critical, such as in fishing lures and counterweights.

Gold melting-sintering furnace, high frequency furnace, shell shaker; post-processing-cutting machine, smoothing machine, sandblasting machine, sand cleaning machine, heat treatment furnace, punching machine; maintenance-pneumatic grinder, argon welding machine, smoothing machine; Quality assurance-spectrometer, three-dimensional, etc. These are relatively common and common, and vacuum casting furnace or vacuum heat treatment furnace or X-ray and so on are needed.
