2. Investment casting exhaust parts description
All modern gasoline cars come equipped with a DPF – Diesel particulate filter. The function of the DPF is to filter and remove out toxic particles out of the exhaust.
The Cast connected boss is apply to DPF system, the manufacture process is investment casting with material stainless steel 304 and machining, surface treatment is electrochemical polishing.

Investment casting, also known as lost wax casting, is a process that involves creating a wax pattern, coating it with a ceramic shell, and then melting the wax out of the shell to create a mold. Molten metal is then poured into the mold to create the final part.

The materials commonly used in investment casting include:

Stainless steel: Stainless steel is a popular choice for investment casting due to its high strength, corrosion resistance, and ability to retain its properties at high temperatures.

Aluminum: Aluminum is lightweight and offers excellent corrosion resistance, making it a popular choice for investment casting in the aerospace, automotive, and industrial sectors.

Copper-based alloys: Copper-based alloys, such as brass and bronze, offer excellent corrosion resistance and are often used in investment casting for decorative and artistic applications.

Titanium: Titanium is a lightweight and strong material that is often used in investment casting for high-performance applications, such as aerospace and medical equipment.

Nickel-based alloys: Nickel-based alloys offer excellent corrosion resistance and high-temperature strength, making them a popular choice for investment casting in the chemical processing and energy industries.

The selection of material for investment casting will depend on the specific requirements of the part, including its strength, durability, and resistance to corrosion and heat. It is important to work with a reputable investment casting supplier who can provide guidance on material selection and ensure that the finished part meets your specifications.
