无论是产品的成功与否，外观设计都是一个不可忽视的重要因素。对于铝合金外壳打样来说，高质量的打样对产品的成功至关重要。铝合金外壳打样的质量主要取决于三个方面：表面处理、尺寸公差和形状精度。
表面处理是铝合金外壳打样的第一步，因为铝材料本身具有较强的腐蚀性，如果表面没有进行良好的处理，则在使用过程中容易发生腐蚀等问题。常见的表面处理方法有氧化、清洗、防锈涂层、抛光等。其中，氧化是目前使用最广泛的表面处理方法，不仅能够有效提高表面硬度和耐磨性，同时还能防止铝材料的腐蚀。
尺寸公差和形状精度是表面处理的基�。绻饬礁龇矫娉鱿治侍猓虮砻娲砥鸩坏接τ械淖饔�。一般情况下，铝合金外壳打样的尺寸公差应控制在0.05mm以内，形状精度应控制在0.1mm以内。
此外，铝合金外壳打样还需要考虑散热性能。由于铝材料具有较强的导热性，所以在设计产品外壳时，需要考虑其导热性能。一般来说，散热性能较差的产品外壳设计较为复杂，因此在选择铝合金外壳打样厂家时需要注意选择具有较强的散热性能的厂家。
虽然铝合金外壳打样质量取决于多种因素，但是只要能够科学的把握这些因素，便能够得到较为理想的打样质量。
Whether the success or failure of the product, the appearance design is an important factor that cannot be ignored. For aluminum alloy shell sampling, high-quality sampling is critical to the success of the product. The quality of aluminum alloy shell sampling mainly depends on three aspects: surface treatment, size tolerance and shape accuracy.
Surface treatment is the first step of aluminum alloy shell sampling, because aluminum itself has strong corrosion resistance, if the surface is not well treated, it is easy to occur problems such as corrosion during use. The common surface treatment methods include oxidation, cleaning, rust-proof coating, polishing, etc. Among them, oxidation is the most widely used surface treatment method at present, which can not only effectively improve the surface hardness and wear resistance, but also prevent the corrosion of aluminum materials.
Size tolerance and shape accuracy are the basis of surface treatment. If there are problems in these two aspects, the surface treatment cannot play its due role. In general, the size tolerance of aluminum alloy shell sampling should be controlled within 0.05mm, and the shape accuracy should be controlled within 0.1mm.
In addition, the heat dissipation performance of aluminum alloy shell sampling also needs to be considered. Because aluminum has strong thermal conductivity, it is necessary to consider its thermal conductivity when designing the product shell. Generally speaking, the heat dissipation performance of the product shell with poor heat dissipation performance is more complex, so when choosing the aluminum alloy shell sampling manufacturer, it is necessary to choose the manufacturer with strong heat dissipation performance.
Although the quality of aluminum alloy shell sampling depends on many factors, as long as these factors can be scientifically grasped, it is possible to obtain more ideal sampling quality.
