Problems solved by technology

The K512 wax currently in use is a mold material specially developed for golf heads. It has the characteristics of good fluidity, easy mold release, and good toughness, but it has a large tendency to deform and is not suitable for making large and complex investment precision castings.
Another commonly used mold material is photosensitive resin mold. Although its strength is high, it can be used to manufacture large and complex titanium alloy castings. However, the molding cycle of this mold material is long and the production cost is high, which undoubtedly affects the profits and profits of foundry manufacturers. delivery date

Description

technical field [0001] The invention relates to the field of titanium and titanium alloy investment precision casting, in particular to a method for preparing a large titanium alloy wax mold for precision casting. Background technique [0002] Titanium alloy investment casting has been developing towards large, complex and thin-walled parts, so higher requirements are put forward for the control of impurities inside the casting, the control of dimensional accuracy and the control of deformation. As the first link of investment precision casting, the selection of wax material is particularly important, and its characteristics directly affect the internal quality and external contour size of subsequent castings. The K512 wax currently in use is a molding material specially developed for golf heads. It has the characteristics of good fluidity, easy demoulding, and good toughness. However, it has a large tendency to deform and is not suitable for making large and complex investm...
