History of Investment Casting parts

January 31, 2023

Investment casting dates back thousands of years. Its earliest use was for idols, ornaments and jewelry, using natural beeswax for patterns, clay for the moulds and manually-operated bellows for stoking furnaces. Examples have been found around the world: from Mexico to Mesopotamia, and Egypt to Africa where the investment casting process produced detailed artwork of copper, bronze and gold.

We are specializing in:

1. Sand casting (Grey iron, ductile iron, aluminum,etc.)

2. Investment casting (carbon steel, stainless steel, alloy steel,etc.)

3 . Die casting(aluminum, zinc, etc.)

3. CNC Machining(CNC Center, CNC lathe, lathe, drilling machine, milling machine, pressing machine, etc.)

The earliest known text that describes the investment casting process was written around 1100 A.D. by Theophilus Presbyter, a monk who described various manufacturing processes, including the recipe for parchment. This book was used by sculptor and goldsmith Benvenuto Cellini (1500 – 1571), who detailed in his autobiography the investment casting process he used for the Perseus and the Head of Medusa sculpture that now stand in the Loggia dei Lanzi in Florence, Italy.

Modern investment casting techniques stem from the development in the United Kingdom of a shell process using wax patterns known as the Investment X Process. This method resolved the problem of wax removal by enveloping a completed and dried shell in a vapor degreaser. The vapor permeated the shell to dissolve and melt the wax. This process has evolved over years into the current process of melting out the virgin wax in an autoclave, or furnace.
