The vacuum casting process typically takes within 24 hours to 5 working days for up to 30-50 pieces. The time frame may vary depending on factors such as the complexity of the design, the number of pieces being cast, and the wall thickness of the mold. A minimum wall thickness of 0.75 mm is required to ensure proper mold filling, but the best results are obtained with a recommended wall thickness of 1.5 mm.
The vacuum casting process involves several steps. First, the temperature needs to be controlled at the right level. The furnace is then vacuumed to a suitable pressure, and the color coating process takes about half an hour to an hour for each PVD coating, with larger pieces potentially taking up to 2 hours. Quality control checking is done to ensure that every corner and surface is well finished.
After the casting process is complete, the casted pieces are air-dried. The color is then checked using a professional measurement machine to ensure it matches the desired color. Finally, each piece is packed with protective packaging to avoid scratching or damage during shipment.
It's important to note that the mentioned references also discuss other topics related to vacuum casting, such as particle acceleration, high-energy physics, radiation therapy, surface coating, deposition and etch, gas delivery, and mass spectrometry. Additionally, the references provide information on vacuum bakeout systems and vacuum furnace designs, but these topics are not directly related to the timeframe of vacuum casting.
