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 1.2m
Permanent mold gravity casting for structural and safety-critical parts. T6 heat treatable, low porosity, superior mechanical properties.
Low-Pressure Casting
Pressure-tight · Near-zero porosity
Counter-gravity fill for complex powertrain housings and components requiring near-zero porosity.
Die Casting
ADC12 · High volume
High-pressure die casting for thin-wall, high-volume components. Fastest cycle times with consistent repeatability.
Sand Casting
Prototypes · No size limit
Flexible expendable molds for prototyping, low-volume runs, and oversized components.
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
16,666 m² of Modern
Casting Infrastructure
Automated gravity casting lines, CNC machining centers, T6 heat treatment furnaces, and a full quality lab with X-ray, CMM, and spectrometer �?all under one roof in Fenghua, Ningbo.
