Customized Grey Iron Precision Casted Base for Thermostat Housing with E-coating

The main differences between grey iron casting and ductile iron casting：

Morphology and mechanical properties of graphite

‌grey iron casting: the form of graphite is flat and sheet-like, which has a great effect on the matrix cleavage, resulting in low tensile strength, ductility and toughness of gray iron. The mechanical properties of grey cast iron range from 100 to 350MPa‌.

Ductile iron casting ‌ : the form of graphite is spherical, this structure has little cleavage effect on the matrix, so the strength, plasticity and toughness of ductile iron are higher. The mechanical properties of ductile iron are in the range of 350-700MPa, and even higher strength ‌ can be achieved through heat treatment.

Manufacturing process

‌Grey iron casting ‌ : The manufacturing process is relatively simple, no special nodularization treatment. ‌

Product Advantages of Customized Grey Iron Precision Casted Base:

• Cost-effective: Combines affordable material with low maintenance and reduced replacement costs.

FAQ:

1Q: Why was Grey Iron chosen as the material?

1A: Grey cast iron has excellent heat resistance, shock absorption and cost effectiveness, suitable for high temperature and pressure environments, while the precision casting process ensures dimensional accuracy and complex structural molding to meet the stringent stability requirements of temperature control systems.

2Q: Is this product suitable for new energy vehicles?

2A: Yes, its high temperature resistance and lightweight design can be adapted to the electric vehicle battery cooling system or hybrid engine, and the corrosion resistance of E-coating meets the requirements of complex working conditions of new energy vehicles.

3Q: Does the product deform or fail at extreme temperatures?

3A: Grey cast iron itself has high heat resistance (usually withstand -20°C to 300°C), combined with the structural strengthening design of precision casting, can maintain dimensional stability under severe temperature differences, ensuring the sealing of the thermostat.

4Q: How many days to make a casting mold?

4A: Basically, it will cost about 20days.

5Q: Can you provide free samples?

5A: Yes, we can provide 3pcs free samples. But customer needs to afford the freight cost.
