This reliability translates to lower maintenance costs and increased uptime for industrial equipment, ultimately boosting productivity and profitability.
Процесс литья под давлением начинается с проектирования пресс-формы, которая определяет форму и размеры конечной детали. Это критический этап, требующий точных расчетов и использования CAD software для обеспечения оптимального flow of molten metal and minimal shrinkage. Современные технологии, такие как simulation software, allow engineers to predict and mitigate potential issues like porosity or warping before production begins. This upfront investment in design pays off in higher quality and fewer defects down the line.
Once the mold is ready, the actual casting process involves melting aluminum ingots in a furnace at temperatures around 600-700°C. The molten metal is then injected into the mold cavity under high pressure, typically ranging from 100 to 1000 bar, depending on the part complexity. The pressure ensures that the metal fills every intricate detail of the mold, resulting in precise and uniform parts. After injection, the metal cools and solidifies quickly, and the mold is opened to eject the finished part. Cycle times can be as short as a few seconds for small components, enabling high-volume production.
Post-casting processes may include trimming excess material, deburring, and surface treatments like painting or plating to enhance appearance and performance. Quality control is integral throughout, with inspections using techniques like X-ray or ultrasonic testing to detect internal defects. This rigorous approach ensures that every part meets specified standards, providing reliability that industries depend on. For example, in the aerospace sector, where safety is paramount, die-cast components undergo extensive testing to certify their integrity.
