INVESTMENT 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.

Tooling Making
Design and kick off tooling according to customers’ specification.

Wax Injection
Injecting molten wax into a mold to create a precise wax pattern.

Wax Pattern Assembly
Welding the wax pattern to the wax rod and add the gate to form a assembly.

Shell Making
Dipping and making shell based on products structure, weight, volume.

Casting
Melt the wax from shell and pour the qualified inspected metal into the shell.

Cutting&Grinding
Remove the shell, cut the parts from the rod, and grind the pouring gate.

Surface Treatment
Shot blasting, shaping, heat treatment, acid pickling and passivation and so on.

Machining
Meet the specific dimensional tolerance requirements of drawings.

Q1. What is the investment casting?
A1. 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.
Q2. What is the process flow of precision casting?
A2. 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.
Q3. What dimensional tolerances can be achieved by investment casting?
A3. 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.
Q4. Why choose investment casting?
A4. 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.
Q5. Where investment casting can be applied?
A5. 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.
Q6. How long does investment casting take?
A6.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.
