The selected mold release agent should not generate gas during die casting and have good mold release performance.<\/p>\n
(3) Ensure that the exhaust of the mold is unobstructed, and that the exhaust is smooth, and that the gas in the mold is completely discharged, especially the exhaust channel must be unobstructed at the final polymerization place of the aluminum liquid.<\/p>\n
(4) Adjust the die-casting parameters, and the filling speed should not be too fast to prevent gas. The casting temperature should also be well controlled.<\/p>\n
(5) Attention should be paid to the use of core pulling and cooling in product design and mold design to minimize excessive wall thickness differences.<\/p>\n
(6) The air holes that often appear in fixed parts should be improved from the mold and design.<\/p>","protected":false},"excerpt":{"rendered":"
