Bengbu Longhua Die Casting Machine Co., Ltd. has released standardized operation specifications for aluminum alloy die casting machine, providing professional and actionable guidance for enterprises to stabilize die casting quality, reduce casting defects and achieve standardized mass production. Scientific operation management is the core key to give full play to the performance of high-precision die casting equipment and improve the yield of aluminum alloy castings.
Strict whole-process monitoring of the die casting process is the primary guarantee for stable product quality. The molten aluminum temperature in the holding furnace must be accurately controlled within ±3℃ to maintain stable stirring temperature. Operators need to adjust the temperature in real time according to the chemical composition of each furnace, stably controlling the solid phase rate at ±2%. Reasonable mold temperature control ensures smooth alloy filling and orderly solidification. Timely adjustment of die casting machine process parameters and regular product inspection effectively avoid defective castings and stabilize overall production quality.
Standardized release agent spraying operation greatly reduces casting defects. Technicians implement differentiated spraying strategies, applying more release agent on difficult demolding areas and less on easy demolding positions. The top-down layered spraying mode discharges residual water in the cavity. For mold-sticking prone positions, short-distance cooling spraying by long-distance film forming effectively prevents water accumulation. Post-spray air blowing removes residual coating in deep cavities and dead corners, eliminating pores, cold shuts and blistering caused by water vaporization.
Professional mold preheating operation protects die casting molds and optimizes production. After mold temperature machine heating, 5 to 10 low-speed liquid alloy casting cycles are adopted for preheating, before switching to formal semi-solid die casting parameters. This standardized process effectively prevents flash and material splashing, extending mold service life and ensuring stable, high-efficiency operation of die casting machinery.
