Aluminum Gravity Casting Built for Global OEMs
Bohua Casting operates under an NQA-certified IATF 16949 quality management system. ISO 9001 requirements are incorporated within the IATF 16949 system; Bohua does not currently hold a separate ISO 9001 certificate. ISO 14001 certification is under application. A356 / ZL114 gravity casting is supported with CNC machining, project-defined pressure-tightness testing, and drawing-based RFQ review.
Application coverage for regulated casting RFQs
Program-fit examples can be discussed during qualified RFQ review.

How We Work
Four Processes.
One Expert Team.
We select the right process for your geometry, volume, and mechanical requirements.
Gravity Casting
A356 · ZL114 — up to approximately 2 m
Permanent mold gravity casting for structural and safety-critical parts. T6 heat treatable, low porosity, superior mechanical properties.
Low-Pressure Casting
Controlled filling · Project-defined pressure-tightness testing
Counter-gravity fill for complex powertrain housings and components where controlled filling, machining stock, and leak-test planning matter.
Die Casting
ADC12 · High volume
High-pressure die casting for thin-wall, higher-volume components, with process fit confirmed from geometry, alloy, and tooling requirements.
Sand Casting
Prototypes · Size reviewed by drawing
Flexible expendable molds for prototyping, low-volume runs, and larger components evaluated against geometry and handling requirements.
Alloys
Right Alloy.
Right Properties.
Gravity / Low-Pressure
Structural, automotive, safety-critical
Gravity / Low-Pressure
High-load industrial, GB standard
Die Casting
High-volume thin-wall, complex geometry
The Facility
13,420 m² of Modern
Casting Infrastructure
Gravity casting, CNC machining, and inspection resources including Hexagon Global S and NANO Metrology CMMs, Oxford OES, 3D scanning, X-ray, tensile testing, and a project-defined pressure-tightness testing workshop in Fenghua, Ningbo.
