Introduction to the History and Process of Lost Wax Casting

Lost wax casting, also known as investment casting, is an ancient manufacturing process that has been around for thousands of years. It dates back as far as 3000 BC in Ancient Egypt and China, and was used to make intricate metal objects and works of art. The lost wax casting process has undergone many improvements and innovations throughout history, and is still an important method for manufacturing parts with high precision and complex geometries.

Basic steps of the lost wax casting process

  1. Mould making: A prototype mould (wax mould) of the product is made from wax or other fusible material.
  2. Shell making: The wax mould is immersed in a ceramic slurry, which is repeatedly dipped and sanded to form a solid shell.
  3. Dewaxing: The ceramic shell is heated so that the wax mould melts and runs out, leaving a cavity.
  4. Casting: Molten metal is poured into the cavity of the ceramic shell and cooled to form a metal casting.
  5. Cleaning and post-processing: Removal of the ceramic shell and excess metal, necessary surface treatment and finishing.

Comparison between 3D printed wax mould and traditional wax mould making

Traditional wax mould making: 

Hand carving: traditional wax moulds are usually hand carved by craftsmen, which is a time-consuming and labour-intensive process, and the accuracy and consistency are harder to ensure.

Mould duplication: For mass production, it is necessary to make master moulds and duplicate moulds, which increases the process steps and costs. 

3D printing wax moulds:

Automated production: 3D printing technology is able to automate the production of wax moulds, reducing the time and labour costs of manual operations.

High precision and complex geometries: 3D printing technology can easily achieve high precision and complex geometries of wax moulds, ensuring consistency and accuracy of each wax mould.

Rapid response to market demand: 3D printing technology can make wax moulds quickly, shorten the production cycle, and quickly respond to market changes and customer demands.

 Through the above comparison, it can be seen that 3D printing wax moulds have significant advantages in terms of precision, efficiency and cost. Therefore, choosing a high-performance 3D printer for wax moulds is crucial for improving the efficiency and quality of the lost wax casting process.

Why choose a wax mould 3D printer?
