1, tolerance formulation should fully consider the manufacturer's production capacity, because aluminum extrusion is formed under hot pressing conditions, the tolerance of the product is relatively rubber parts, hardware to be large. 2. The thickness of the material should not be too thin. In principle, it should be more than 0.8mm, with less deformation, better extrusion condition and mass production. 3, hollow pipe material thickness difference can not be too large, generally not more than 4 times, otherwise the mold is difficult to trim and extrusion. 4. Before formally opening the mold, detailed surface process effect must be provided. Because the surface treatment process affects the determination of the closing line of the extrusion mold in the early stage, it affects the value of the size of the extrusion mold and the metal stamping mold (oil injection will make the product aperture smaller, the shape larger, the inner cavity narrower, while oxidation is the opposite; Sandblasting can cause the product aperture to become larger, the body to be thin, or cause the product to deform; in the wire drawing process, the material should be considered to leave a margin). 5. The extruded material cannot make absolute sharp corners. The sharp-angled aluminum profile in the design will have an R angle of about 0.3. After subsequent polishing, oxidation, oil injection and other processes, the R angle will reach about 0.4. 6. The proportion of hollow and solid parts of aluminum extrusion shall not be too wide or too large, depending on the actual structure.
