Why Engine Castings Fail? The Lost Foam Fix

Added: 2026-05-16

[00:00:00]Fellow workers, why does sand sinking cause such high scrap rates in engine cylinder block casting? The answer lies in advanced lost foam casting technology. It eliminates mold parting, reduces machining allowances, and achieve higher dimensional accuracy.

[00:00:16]Vacuum low pressure improves filling ability. Vibration refines grains, and shell casting enhances surface quality.

[00:00:22]Surface roughness drops to just 3.2 6.3 micrometers. Numerical simulation helps forecast mold filling and solidification [music] behavior. Reduces iterative dodging costs and shortens product development cycles effectively. This technology is revolutionizing automotive, aerospace, and petroleum machinery manufacturing with higher quality and efficiency.
