molten metal must have sufficient fluidity to fill the entire mold cavity, including intricate details (e.g., thin walls, small holes, complex contours). Fluidity is influenced by the metal\u2019s composition, melting temperature, and the addition of alloys or fluxes.<\/li>\n<li>&#8211; Solidification Behavior: As the molten metal cools, it undergoes a phase change from liquid to solid. Uniform solidification is critical to avoid defects such as shrinkage, porosity, or cracks. The mold\u2019s material and design (e.g., venting, gating) play a key role in controlling cooling rates.<\/li>\n<li>&#8211; Mold Release: The mold must be designed to allow easy removal of the solidified prototype without damaging its surface or geometry. This often involves using mold releases (e.g., wax, oil, or ceramic coatings) or creating molds with draft angles (tapered surfaces).<\/li>\n<li>&#8211; Dimensional Accuracy: The mold\u2019s cavity must be precisely shaped to match the prototype\u2019s design specifications.

Shrinkage during solidification can cause minor dimensional variations.<\/li>\n<li>&#8211; Surface Finish: Most prototype casting methods (e.g., sand casting) produce rough surface finishes that require additional finishing (e.g., grinding, polishing) to meet the final product\u2019s requirements.<\/li>\n<li>&#8211; Defect Risk: Common defects include porosity (air bubbles), shrinkage holes, cracks, and flash. These defects can be minimized by optimizing mold design, pouring parameters, and metal treatment.<\/li>\n<li>&#8211; Material Limitations: Some casting methods (e.g., plaster casting) are not suitable for ferrous metals or high-temperature alloys. The choice of metal may be limited by the mold\u2019s heat resistance.<\/li>\n<\/ul>\n<h2>7. \u062a\u0637\u0628\u064a\u0642\u0627\u062a \u0635\u0628 \u0627\u0644\u0646\u0645\u0627\u0630\u062c
