Engine housings are critical structural components in internal combustion engines and electric powertrains. They provide mechanical support, house key moving parts, and contribute to heat dissipation and lubrication flow. Due to their complex geometry, thin wall sections, and strict dimensional requirements, high-pressure die casting is a preferred manufacturing method for aluminum engine housings.
Our precision die casting process delivers consistent wall thickness, good surface finish, and high dimensional accuracy, making the parts suitable for further CNC machining and assembly in automotive and industrial applications.
Process: High-pressure die casting (HPDC)
Tooling: In-house mold design and manufacturing
Machining: 3-axis, 4-axis, and 5-axis CNC machining for critical surfaces
Surface Treatment (optional): Shot blasting, powder coating, e-coating, machining, and deburring
We provide end-to-end manufacturing from mold design to finished engine housings, covering die casting, machining, and finishing processes.
Lightweight aluminum structure
Good heat dissipation performance
High dimensional accuracy
Strong structural integrity
Suitable for high-volume production
Compatible with secondary machining and assembly processes
Common aluminum alloys used for engine housings include:
ADC12 / A380 – good castability and surface quality
A356 – higher mechanical strength when required
Material selection depends on engine type, operating temperature, mechanical load, and machining requirements.
Precision die-cast engine housings are widely used in:
Passenger cars
Commercial vehicles
Motorcycles
Electric vehicles (EV) and hybrid powertrains
Small industrial engines
X-ray inspection for internal defects
Dimensional measurement using CMM
Visual surface inspection
Leak testing when required by design
Each engine housing undergoes quality inspection to ensure structural reliability and dimensional consistency.
In-house mold design and manufacturing
DFM (Design for Manufacturing) support
Prototype and mass production capability
Flexible order quantities
Experience serving automotive and industrial clients
