作者提出用铝芯盒,木模制造砂型浇铸表面镀铜的铋锡合金母叶片,据此制造模型再浇铸叶片或工作轮。此方法较精确,适于小批量生产。
The authors propose that aluminum-core boxes and wood-based molds be used to produce sand-cast copper-plated bismuth-tin alloy mother blades, from which molds may be cast to re-mold the blades or work wheels. This method is more accurate, suitable for small batch production.
