HPL- Automotive & Engineering Foundry

Goal

Optimizing Green Sand Performance to Improve Casting Quality in a Multi-Unit Automotive Foundry

Outcome

• Bentonite consumption reduced by 16.56% (81.5 to 68 kg/LMT).
• New sand consumption reduced by 9.72% (36 to 32.5 kg/LMT).
• Foundry rejection reduced by 7.60%; mould drop eliminated 100% during trial.
• Dirt/inclusion defects reduced by 20.00%.
• Blow hole defects reduced by 8.86%.

Net result: improved casting surface finish and peel-off, better mould integrity, and consistent moulding results — Lustron HPL strongly recommended for regular production.
