CNC aluminum alloy is a common precision processing material for mould accessories, widely used in auxiliary structural parts of low-pressure moulds, extrusion moulds and stamping moulds. Different from die steel used for mould cavities, CNC aluminum alloy is mainly used for mould base, positioning auxiliary parts and cooling structural parts, with the advantages of light weight, easy processing and fast heat dissipation. Xinfeng Machinery reasonably matches CNC aluminum alloy accessories in mould design to optimize overall mould performance.
The mainstream CNC aluminum alloy material for mould accessories is 6061-T6 high-precision aluminum, with stable mechanical properties and excellent processing performance. Its tensile strength reaches 310MPa and yield strength reaches 276MPa, which can resist minor extrusion and impact deformation in mould operation, fully meeting the bearing requirements of mould auxiliary structures. Compared with ordinary industrial aluminum, 6061-T6 material has internal stress eliminated after T6 heat treatment, with long-term dimensional deformation rate less than 0.02%, ensuring stable matching precision of mould accessories.
CNC precision processing technology ensures high matching accuracy of mould parts. Professional five-axis CNC processing can control part tolerance within ±0.005mm, realizing zero-gap assembly of mould auxiliary structures, avoiding positioning deviation and jamming faults in mould operation. After surface anodizing treatment, the corrosion resistance and oxidation resistance of aluminum parts are improved by 40%, adapting to long-term high-temperature and humid casting workshop environment, effectively extending accessory service life.
The lightweight and heat dissipation advantages of CNC aluminum alloy optimize overall mould performance. Aluminum alloy density is only 2.7g/cm³, 25% lighter than steel structural parts, which can reduce overall mould weight and improve the flexibility of mould installation and debugging. Its high thermal conductivity accelerates mould auxiliary heat dissipation, reducing local temperature difference of the mould by 12% and indirectly reducing thermal crack failure probability of the mould cavity.
It is necessary to distinguish that CNC aluminum alloy is only suitable for mould auxiliary structural parts, not for mould cavity forming parts. The high-temperature resistance and wear resistance of aluminum alloy are far lower than die steel, and it will deform and wear rapidly under high-temperature molten metal scouring and cyclic pressure, so it cannot replace H13 and SKD61 die steel for cavity manufacturing.
