Repair plan for erosion of die-casting mold gate sleeve
Date:2025-12-03 14:07     Source:daokedao     Browse:5

The gate sleeve of the die-casting mold is subjected to long-term erosion by high-temperature metal liquid (600-700 ℃), resulting in 0.2-0.5mm pits on the inner wall, leading to uneven flow of the metal liquid and a porosity of over 8% in the product. Daokedao adopts high-temperature wear-resistant alloy cladding technology, using Ni-Cr-Al-Y alloy powder, with an inner wall cladding layer thickness of 0.3-0.6mm, a hardness of HRC50 at 600 ℃, and a 3-fold increase in erosion resistance. By using the rotary cladding process, the inner wall is ensured to be uniform, the inner diameter tolerance is controlled within ± 0.02mm, and the flow efficiency of the molten metal is improved by 20%. The repair cost of the Φ 50mm sprue sleeve is 800 yuan, saving 4200 yuan compared to new parts, and extending the lifespan from 6 months to 24 months. After application in a certain die-casting factory, the porosity of the product decreased from 10% to 1.5%, the pass rate increased to 99%, and the tensile strength of aluminum alloy die-casting parts increased by 12%. It is suitable for repairing easily eroded parts such as zinc alloy and aluminum alloy isobaric mold gate sleeves and diversion cones.
