模具濟(jì)南鋁板http://www.pdadn.com/的生產(chǎn)加工方式屬于軋制加工，又稱(chēng)為“壓延”加工。一般采用兩種方式：熱軋和鑄軋。熱軋法的特點(diǎn)：在大塑性變形過(guò)程中，內(nèi)部組織經(jīng)歷了多次回復(fù)、再結(jié)晶模具模具鋁板，將鑄造狀態(tài)的粗大晶粒破碎，顯微裂縫愈合一枝獨(dú)秀，使坯料在內(nèi)部組織的均勻化、晶粒的尺寸與形狀、點(diǎn)缺陷與線(xiàn)缺陷濃度變化等鑄造缺陷方面模具模具鋁板，均獲得顯著改善，使鑄態(tài)組織轉(zhuǎn)變?yōu)樽冃谓M織，大大提高了金屬的加工工藝性能。特別是在深沖性能方面，熱軋料有著鑄軋料不可比擬的優(yōu)勢(shì)。鑄軋法的特點(diǎn)：鑄軋板的內(nèi)部組織屬于半鑄態(tài)結(jié)構(gòu)，晶體的方向性較強(qiáng)。與熱軋相比尷尬局面，具有投資少、成本低、效率高的特點(diǎn)。
Jinan remind car modified car stereo sound absorption characteristics are not the same kinds of materials for sound absorption is different, but there are differences in the same kind of material to absorb the force of each frequency

also. Therefore, due to the different interior decoration materials and chairs, there will be some impact on the sound effects. General interior decoration, car seat, roof and flooring materials such as cloth and skin rugs, inside of the use of synthetic leather, as well as listening and the doors and windows, in the high-frequency sound-absorbing characteristics will be more complex formation, in hearing on the high frequency will be relatively strong, so the relatively high frequency soft music, it will not easy to make people irritable and tired.　　
　　
模具濟(jì)南鋁板http://www.pdadn.com/是指用鋁及加工而成的板型材料，合金模具濟(jì)南鋁板還可以分為冷軋和熱軋最低增速模具模具鋁板，主要區(qū)別是以陽(yáng)極氧化為區(qū)別模具模具鋁板，熱軋模具濟(jì)南鋁板可以做陽(yáng)極氧化。冷軋模具鋁板和熱軋模具鋁板用途不同迅速蔓延，冷軋模具濟(jì)南鋁板多用于模具類(lèi)，熱軋模具鋁板適合沖壓拉伸方面。同樣的材質(zhì)由于制作工藝不同，它的物理性能相差很大。又被稱(chēng)為塑性成形，按鋁材在變形過(guò)程中的受力與變形方式（應(yīng)力—應(yīng)變狀態(tài)）分為：鑄造、鍛造、擠壓、旋壓、拉拔、軋制、成形加工（冷壓、深沖）等加工方式。
Jinan aluminum mold refers to the processing of aluminum and plate material, aluminum alloy die Jinan can also be divided into cold-rolled and hot-rolled aluminum die die lowest growth rate, the main difference is the difference between

the anodic oxidation of aluminum mold mold, hot Jinan mold can do anodized aluminum. Cold-rolled and hot-rolled aluminum mold mold aluminum uses different spread rapidly, cold-rolled aluminum sheet used for mold mold Jinan class, hot stamping dies for aluminum stretched on. The same material due to the different production process, its physical properties vary greatly. Also known as plastic forming, aluminum during deformation by the force and deformation mode

(stress - strain state) is divided into: casting, forging, extrusion, spinning, drawing, rolling, forming (cold , deep drawing) and other processing methods.
