738H Metal Casting Molds for Cylinder Heads with 500K-1M Shots Life

Eliminate chronic casting defects with our problem-solving metal casting moulds for cylinder head sand cores. Integrating CFD-validated vent networks (<0.2mm micro-vents) and thermal distortion control, these moulds prevent sand erosion, gas blows, and veining in high-stress areas (exhaust ports, spark plug bosses). Every tool undergoes X-ray casting validation to guarantee pressure integrity - reducing scrap rates by up to 90%.

• 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.
