Specialized in the design of aluminum die-casting design people know that the die wall thickness of the casting quality has a great impact on the casting wall is too thick, the wall is too thin are not good, so the design of die casting should be reasonable design of its wall thickness, The quality of the press is not affected by the wall thickness.
In the case of aluminum alloy die castings, under normal circumstances, thin-walled thick-walled die castings with higher strength and better density, in view of this, die casting design should follow the principle: to ensure that the casting has sufficient strength And rigid under the premise should be as much as possible to reduce the wall thickness, and keep the wall thickness uniformity. Practice has proved that die casting wall thickness design is generally 2.5-4mm is appropriate, wall thickness of more than 6mm parts should not be used to produce die-casting process.
Die wall is too thick, the wall is too thin on the impact of the quality of casting performance: If the design of the casting wall is too thin, will make the metal welding is not good, directly affect the casting strength, while the molding will cause difficulties; wall is too thick or serious uneven When the wall thickness, shrinkage and other defects also increased, the same will reduce the casting strength, affecting the quality of castings.
