1) hand molding and semi-mechanized molding sand box structure: This sand box, mostly single-walled structure with handles for flipping and handling or transfer shaft, a considerable number of tank wall vents, the use of the entire cast style, it also welded steel or other material from the system. According to process requirements, sand box shape can be made rectangular, square, circular or other shapes. Pneumatic microseismic, injection pressure, high pressure, air impact, high specific pressure molding machine as the host of automated flow molding line with the flask to the work process: (2) with high host automated molding lines flask with specific pressure molding machine for the withstand high pressure, EPC sand box layer requires better ventilation, better sealing outer requirements, special requirements so that its structure is very complicated, making trouble, as long as there are places a little sloppy, high-density sand box, sand production After the box into production, the production of castings will have a variety of problems, sand box molding line manufacturers, such as the collapse box, porosity, sand box molding line price, shrinkage, etc. Therefore, the flask is EPC equipment One of the key equipment. Gaomi flask molding line _ _ Dragon Industrial sand box price provided by the Industrial Development Co., Ltd. Shandong dragon. Gaomi flask molding line _ _ Dragon Industrial sand box price Shandong dragon Development Co., Ltd.
