Steady and far-reaching, casting the core of vacuum-high-performance gray iron vacuum pump casting, driving a clean and efficient future

Vacuum technology is an indispensable "behind-the-scenes hero" in semiconductor, medical care, new energy, scientific research and other fields that require high cleanliness and stability. As the core structure of vacuum pump, gray iron casting silently supports every high-precision pumping and stable operation with its unique physical properties and excellent process adaptability.

Why is gray iron an ideal choice for vacuum pump castings?

Gray Iron has three key advantages by virtue of its flaky graphite microstructure:

• Outstanding shock absorption performance: effectively absorb the mechanical vibration in the operation of the pump body, reduce the noise and improve the stability of the whole machine;
• Good air tightness and compactness: through precision casting and post-treatment process, the internal structure of the casting is ensured to be uniform and the risk of micro-leakage is reduced;
• Excellent wear resistance and thermal fatigue resistance: adapt to the harsh working conditions of long-term continuous operation of vacuum pump and prolong the service life of equipment.

Precision casting, reliable details.

We focus on providing customized gray iron casting solutions for high-end vacuum pump manufacturers, covering key components such as pump casing, end cover and bracket. Ensure quality through the following processes:

✅ Control of high-purity raw materials: strictly screen pig iron and alloy elements to ensure the consistency of components;
✅ Precision molding of resin sand/coated sand: one-step molding of complex runner and thin-walled structure is realized, and the dimensional accuracy is above CT8;
✅ Complete heat treatment and aging process: eliminate casting stress, prevent deformation in use and ensure long-term sealing performance;
✅100% NDT: X-ray, ultrasonic or penetrant inspection to eliminate internal defects and protect the absolute reliability of vacuum system.

Used in cutting-edge fields and won global trust.

Our gray iron vacuum pump castings have successfully served molecular pumps, rotary vane pumps, Roots pumps and other types of equipment, and are widely used in:
