Newly customized low-pressure moulds cannot be directly put into mass production; professional trial run debugging and parameter calibration are required to eliminate unstable factors. Unreasonable initial parameter setting is the main cause of low qualification rate and frequent defects in the early stage of mould production. Standardized batch debugging procedures can quickly optimize process parameters, realize stable mass production, and save a lot of trial production time and material cost for enterprises. Xinfeng Machinery summarizes mature three-stage mould debugging standards for industrial production.
The three-stage trial run debugging includes empty mould preheating trial, small-batch sample trial and continuous batch trial. Empty mould debugging checks mould opening and closing, ejection reset and sealing performance to eliminate mechanical faults. Small-batch sample trial optimizes core parameters such as filling pressure, mould temperature and cooling time to solve single-piece defect problems. Continuous batch trial verifies production stability, eliminating 95% of initial production abnormal problems.
Precise pressure and temperature calibration is the core of debugging. Low-pressure casting pressure is precisely adjusted and stabilized within ±0.002MPa fluctuation range, ensuring stable molten aluminum filling speed and uniform cavity filling. Mould temperature balance debugging controls internal temperature difference below 50℃, completely solving batch shrinkage porosity, deformation and size fluctuation defects caused by uneven temperature.
Parameter solidification and file management improve subsequent production efficiency. All optimized stable process parameters are recorded and solidified to form exclusive mould parameter files, avoiding repeated debugging every time the machine is started. This mechanism reduces subsequent production debugging time by 60% and greatly improves production continuity.
Post-debugging comprehensive inspection ensures long-term stable operation. After trial run, the mould vent slots, cooling channels, ejection structure and cavity surface are fully inspected to eliminate potential hidden dangers such as blockage, wear and loose matching, with hidden danger elimination rate up to 98%.
