INVESTMENT CASTING

known as precision casting or lost wax casting

Investment casting, as known as precision casting or lost wax casting, is a process used to manufacture complex metal parts with high accuracy and surface finishing. It can meet the manufacturing requirements of complex shapes, fine details, thin walls and tight tolerances.

Suijin provide high precision,high quality investment casting services, can provide one-to-one targeted solutions according to drawing dimension tolerances to satisfy customers.

ADVANTAGES OF Investment casting

Investment casting can take advantage of the flexibility of almost any metal materials, such as carbon steel, stainless steel,alloy steel…… for a variety of industries and applications, including aerospace, energy, automotive……

High precision and complex

Capable of producing complex shapes, fine details, thin walls to meet dimensional tolerances and high assembly requirements.

Customization

Through “CASTsoft” software to simulate casting customized production, determine the production process, improve product quality.

Flexibility of design

Precision casting offers design flexibility, allowing large and small parts with complex structures to be tested and validated prior to mass production.

Cost Saving

Direct casting, reduce material waste, more efficient, and high quality surface finish reduce subsequent processes, save time and costs.

Various material

Precision casting can be applied to various metals, allowing flexibility in the choice of materials for strength, corrosion resistance or heat resistance.

Consistency and stability

The complex details and surface features of the original model can be accurately reproduced, ensuring stable and consistent production.

Q&A about customized investment Casting

Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process used to produce complex and detailed metal components with high dimensional accuracy.
It involves creating a wax pattern, coating it with a ceramic shell, melting out the wax, and then pouring molten metal into the resulting cavity to obtain the final cast metal part.
Investment casting can achieve dimensional tolerances ranging from ±0.1 mm (0.004 inches) to ±0.025 mm (0.001 inches) per 25 mm (1 inch) of dimension, depending on various factors such as the size and complexity of the component, the material used, and the specific requirements of the application.
Investment casting provides design flexibility, excellent surface finish, high dimensional accuracy, and material versatility, making it a preferred manufacturing process for complex and intricate metal components.
Investment casting can be applied in various industries and applications, including aerospace, automotive, defense, medical, jewelry, energy, and general manufacturing, where complex and intricately shaped metal components with high precision, excellent surface finish, and material versatility are required.
The duration of the investment casting process can vary depending on several factors, including the complexity and size of the component, the material being cast, the number of steps involved, and the specific requirements of the project. Generally, investment casting can take anywhere from a few weeks to several months to complete.
