Utilizing 3D printing rapid prototyping technology, they drastically shorten mold manufacturing cycles. Traditional mold making requires complex processes and lengthy time, while these molds offer rapid delivery. They can precisely construct complex gating structures to meet diverse casting requirements, ensuring uniform and stable flow of molten metal into the mold cavity and guaranteeing casting quality. Compared to traditional molds, they are customizable, highly flexible, and reduce mold development costs. They are widely used in aerospace, automotive manufacturing, and other fields with high precision requirements for castings, driving the development of the precision casting industry.

[0003] Existing rapid prototyping 3D printed investment casting precision runner molds mainly include a fixed template and a moving template.
