The nickel alloy 718 2-layer gasket is used in automotive industry. The two - layer structure of the gasket is designed to enhance its sealing performance, or to meet specific application requirements.
Material and process
This part is made of special material gasket in nickel alloy 718. Nickel Alloy 718 is a precipitation-hardened nickel-based superalloy, it has excellent high-temperature strength, corrosion resistance, and weldability. It is extremly hard material to punch, also this nickel alloy material has excellent ability to resist rusty.
We possess quality certification documents for this material (Nickel Alloy 718), which are issued by authoritative third-party institutions and strictly comply with international standards. Nickel Alloy 718 is available in various forms, including rolls and plates, finally we choose the thickness of 0.25mm sheet to work the gasket. As the pictures shows:
material of 718 quality certificated
roll of material nickel alloy 718
thickness 0.25mm 718 sheet
Then the material is arrived and cut into pieces.
50kgs of mateiral 718 nickel alloy arrived
cut the sheet into pireces
When the materials arrived, we conducted chemical composition test and hardness test on them, as shown in the images below.
The gasket 3D drawings is from our costomer, and decided to use punching process to work the product after our engineers analysing it.
For normal stainless steel, the regular process is to punch the outline first, then deep drawn the center rib.
But for the special hard material, the safe process is to deep drawn the center rib first, the punch the outline, or it will twist. After succeed, then put two plate spot welding together. The finished 718 gasket as the below picture.
Packing
After inspecting the product dimensions, we proceed with packaging. These finished gaskets were put into boxes and laid the boxes on the pallet, wrapped protective film around the box and pallet. This process ensures products are protected against transit damage.
In addition, there are different type of gasket developed by our factory.
Ningbo Joyo Metal Parts Co,.Ltd. is a professional custom metal parts manufacturer with more than 14 years experience, not only can master all kinds of processes, but also specialize in various material, such as aluminum alloy, steel, stainless steel, zamak, nickel and so on. We can also integrate various different process to satisfy one-stop services.
