Custom Stainless Steel Precision Castings

Taiyuan SIMIS Investment Casting Co., Ltd has 6 affiliated investment casting foundries. Investment casting manufacturer through lost wax casting process in China, we have one of the world’s most advanced silica sol investment casting techniques. The complete implementation of silica sol binders in investment casting has revolutionised the process in several key ways:

• Replacing environmentally harmful curing agents with silica sol improves the working environment and enhances the quality of castings.
• Drying time for the silica sol shells has been drastically reduced from 8 hours to just one hour per layer, significantly boosting production efficiency and shell strength.
• This innovation has expanded the application of silica sol technology to encompass a wider range of materials, including carbon steel and various alloy steels, while also enabling the production of larger investment casting parts weighing up to 50 kg. This expansion not only diversified our offerings but greatly reduced production costs, especially for carbon and alloy steels that were historically costly to produce using silica sol binders.
• The introduction of a fully automated shell-making process, incorporating mechanical handling and automatic drying. This system has the capacity to create up to 8 layers of shells, with each layer managed by a separate automated unit, ensuring precise control and eliminating human-operated variability.
• we have created shells with markedly greater strength compared to conventional silica sol binders. At the same time, we have succeeded in reducing shell thickness by nearly half. This decrease in thickness improves shell permeability and is instrumental in achieving the high-quality surface finish of our castings.
