A casting mold is the core tooling used in the casting process to form the shape and dimensions of castings. Essentially, it is a hollow container with a specific cavity, serving as the critical bridge between raw materials and the final formed workpiece. During casting, molten liquid metals, alloys, or non-metallic materials (such as resins or ceramics) are poured into this cavity. After cooling and solidification, breaking or opening the mold yields a solid part—the “casting”—that perfectly replicates the cavity's shape. Casting molds directly determine the dimensional accuracy, surface quality, and structural integrity of castings, making them widely used in automotive, machinery manufacturing, home appliances, hardware, and other industrial sectors.
二、Advantages
Strong Complex Forming Capability: Directly casts hollow, thin-walled, and irregularly shaped structural components with minimal post-processing, achieving near-net-shape forming suitable for complex parts like aircraft engine blades.
Broad Material Compatibility: Casts metals (e.g., cast iron, aluminum alloys, titanium alloys) and non-metals (e.g., resins, ceramics) to meet diverse industry performance requirements.
High Batch Efficiency: Molds are reusable, with unit costs decreasing as production volumes increase. Processes like die casting produce one part every few minutes, making it suitable for high-volume manufacturing like automotive wheels.
High Material Utilization: Optimized pouring systems minimize waste, and sprue metal is recyclable, achieving over 90% material utilization in investment casting.
Stable Performance: Controlled cooling refines grain structure and minimizes defects. Batch-to-batch performance variation is ≤5%, ensuring reliability under high-load conditions.
Design Flexibility: Short development cycles for small-to-medium molds support custom small-batch production and lightweight designs, enabling rapid response to product iterations.
