Metal Casting Mould for Cylinder Head Gravity Casting Sand Cores Precision CNC Tooling

We engineer high-performance metal casting moulds specifically for producing defect-free sand cores used in aluminum/iron cylinder head gravity casting. These CNC-machined core boxes (H13 tool steel, HRC 48-52) feature FEA-optimized cavities that replicate complex coolant channels, oil galleries, and combustion chambers with micron-level accuracy – ensuring leak-proof engine castings for automotive, marine, and power generation industries.

Key Features & Advantages:

• Zero-Porosity Guarantee: Laser-calibrated venting systems eliminate gas entrapment in thin walls (down to 3mm).

• Extended Tool Life: Tungsten carbide inserts in high-erosion zones sustain 200,000+ cycles.

• Thermal Stability: Conformal cooling channels maintain ±8°C uniformity during resin curing.

• Rapid Changeover: Modular inserts switch between V6/V8/I4 architectures in <15 mins.

• Automation Ready: Integrated KUKA/FANUC interfaces enable robotic core handling.
