Product Specification

The core of calmness, the foundation of galloping-high-precision gray iron automobile water pump shell casting, which will protect the engine for a long time

 In the automobile power system, the engine is the "heart" and the water pump is the "blood circulation center" to maintain its healthy operation.

As the core component of the cooling system, the automobile water pump shell must be sealed, stable and durable under severe working conditions of high temperature, high pressure and continuous vibration.

We focus on developing and manufacturing high-quality gray iron (HT250/HT300) automobile water pump shell castings, and provide reliable power guarantee for global automakers and Tier 1 suppliers with excellent material properties and precision casting technology. 

Why is gray iron an ideal material for automobile water pump housing?

Excellent thermal conductivity and thermal stability: gray iron can quickly conduct and evenly disperse engine heat, effectively preventing deformation or cracking caused by local overheating.

Excellent shock absorption and noise reduction performance:

flake graphite structure naturally absorbs vibration, significantly reducing the running noise of water pump and improving driving comfort. 

Good wear resistance and sealing:

the dense matrix is matched with the precision machined surface to ensure perfect cooperation with water seals, bearings, impellers and other parts, so as to prevent coolant leakage. 

Mature casting process adaptability: good fluidity and small shrinkage, suitable for one-time molding of complex inner cavity structure, reducing the risk of subsequent welding or assembly.

Core advantage High dimensional accuracy & surface smoothness: resin sand or coated sand technology is adopted, and the tolerance between the key installation surface and sealing surface reaches IT8 level, which meets the requirements of automatic assembly.

 Strict process control:

from melting components to heat treatment, the whole process is digitally monitored to ensure batch consistency. 

Lightweight optimization design support:

under the premise of ensuring strength, help customers realize structural weight reduction and help save energy and reduce emissions. 

Meet the automotive industry standards: meet the requirements of IATF 16949 quality system, and support the delivery of PPAP, MSA, SPC and other full-process documents. 

Widely used, supporting mature

 Our gray iron water pump housing has been successfully applied to:

 Cooling system for gasoline/diesel engine of passenger car Auxiliary cooling module of new energy range extender

Power unit of commercial vehicles and construction machinery

Aftermarket replacement parts (AM market) Quality comes from the persistence of detail.

Each shell passes through: 

Spectral component analysis+metallographic detection X-ray or penetrant inspection (key parts)

Water pressure/air tightness test (up to 2.5MPa) CMM three-coordinate full-size re-inspection

We are well aware that a tiny sand hole or deformation may cause the failure of the whole machine.

Therefore, zero defect is our commitment to customers. 

Choosing our gray iron automobile water pump shell casting means choosing:
