Scientific LPDC casting mold cooling channel layout stabilizes mold temperature, reduces defects and extends service life with fixed industrial parameter standards.
The standard spacing of LPDC mold cooling channels is 12–20mm, with 15mm as the optimal value for balancing cooling efficiency and mold structural strength.
The distance between cooling channels and mold cavity is controlled at 8–12mm, avoiding cavity deformation caused by excessive local temperature difference.
Thin-wall areas of aluminum wheel mold and EV structural part mold adopt dense 12mm spacing channels to accelerate uniform solidification.
Procast CAE simulation verifies that standardized channel layout reduces mold temperature difference by 32% and lowers thermal fatigue cracking risk.
Cooling channel diameter of conventional LPDC molds is 8–10mm, matching 6–8m³/h circulating water flow for stable heat dissipation.
H13 hot-work steel molds with standard cooling layout extend average service life by 18% compared with irregular channel design molds.
Gravity casting mold channel spacing is 15–22mm, wider than LPDC molds, adapting to slow solidification of thick-wall castings.
CPC counter-pressure casting mold adopts 10–16mm dense channels to meet rapid cooling demand under high-pressure casting conditions.
Reasonable cooling layout reduces casting mold porosity shrinkage by 25%, eliminating shrinkage defects caused by unbalanced solidification.
Casting mold trial-test shows that unqualified channel layout increases casting deformation rate by 38% in continuous production.
Cooling water channel is one of the core functional structures of LPDC casting mold, directly determining mold temperature field stability and casting forming quality. In aluminum alloy casting production, uneven mold temperature is the main cause of shrinkage cavity, porosity and casting deformation. Industrial standardized cooling channel layout covers spacing, cavity distance, pipe diameter and overall distribution rules, applicable to aluminum wheel mold and EV structural part mold mass production. Different from gravity casting mold and CPC counter-pressure casting mold, LPDC molds need more precise and dense cooling layout due to thin-wall and high-precision casting positioning. Professional Procast CAE simulation can iterate and optimize channel parameters in advance, predict temperature field changes in the full molding cycle, and eliminate unbalanced cooling risks. H13 hot-work steel has good thermal conductivity, which can maximize the heat dissipation efficiency of standardized channels. Strict casting mold trial-test verifies the actual cooling effect of the channels to ensure no local overheating or slow cooling dead zones. Standardized cooling design not only reduces casting mold porosity shrinkage and deformation defects, but also effectively reduces mold thermal fatigue loss, extends mold service life, and reduces enterprise mold replacement and maintenance costs in long-term industrial production.
