Lost wax casting: process, applications and future

July 4, 2024

Lost wax casting, as an ancient and exquisite metal casting technology, has occupied a pivotal position in the fields of artwork, jewelry and industrial manufacturing since ancient times. Learn more Lost wax casting background and practical significance.With the progress of the times and the development of science and technology, the lost wax casting technology is also constantly innovating and perfecting, and has become an indispensable part of the modern manufacturing industry. This article will introduce the lost wax casting process, application and future development, leading the reader to appreciate the charm of this ancient craft.

Lost wax casting process overview

Lost wax casting, also known as investment casting or precision casting, is a use of fusible materials (such as wax) made of fusible model, and in its surface covered with refractory materials made of casting, and finally through the heating to make the model melt out, so as to get the required metal casting casting method. This process has the advantages of high precision, high complexity, high surface quality, etc., and is capable of producing a variety of metal parts with complex shapes and fine structures.
The basic process of lost wax casting includes: wax mold making, mud wrapping, wax mold melting out, metal casting and post-processing.

  • First, an accurate wax mold is made using a fusible material (e.g., wax) based on the design drawings of the part.
  • Then, a refractory material (e.g., mud) is applied to the surface of the wax mold to form the casting.
  • Next, the pattern is heated until the wax mold melts, allowing the wax material to flow out and form a cavity.
  • Finally, molten metal is poured into the cavity and after it has cooled and solidified, the casting is removed and post-processed, such as grinding and polishing.
