Abstract

The invention discloses a method for preparing a casting medium-temperature model wax. The invention belongs to the technical field of casting materials. The casting medium-temperature model wax prepared by the preparation method disclosed by the invention has outstanding and excellent flow properties, and is extruded and granulated by solid billets. Applied to hardware parts, it has excellent stability, high strength, and high surface finish. Its excellent performance makes it widely used in various shapes and sizes of parts, especially in small and medium-sized products and thin-walled parts. The preparation method is simple , low ash content, good toughness, good reusability, good dimensional stability, low viscosity, good fluidity, good surface quality of wax parts, and good adhesion.

Description

technical field [0001] The invention relates to the technical field of casting materials, in particular to a method for preparing casting medium-temperature model wax. Background technique [0002] Precision casting is also called investment casting. Precision casting was also used in ancient my country. It was called the lost wax method in ancient times. Therefore, my country is also one of the birthplaces of precision casting technology. At present, several precision casting methods commonly used in factories can meet the actual production needs, but the performance index of the mold material is directly related to the quality of precision castings, which directly affects the dimensional accuracy and quality of precision castings. Therefore, for the size and quality control of mold material castings, higher requirements must be put forward. The performance requirements that the mold material needs to meet are as follows: there must be a small linear shrinkage rate and the ...
