7, if there is a hydraulic core-pulling, hydraulic parts and mould maintenance at the same time.Hydraulic parts service pay special attention to clean, prevent pollution, otherwise will be the whole die casting machine hydraulic system pollution.
8, when the mould is in manufacturing process failure or damage, should be in accordance with the specific circumstances to determine the repair scheme.The mold must develop a plan of the corresponding maintenance at ordinary times.
