模具济南铝板http://www.jngdly.com/的生产加工方式属于轧制加工，又称为“压延”加工。一般采用两种方式：热轧和铸轧。热轧法的特点：在大塑性变形过程中，内部组织经历了多次回复、再结晶模具模具铝板，将铸造状态的粗大晶粒破碎，显微裂缝愈合一枝独秀，使坯料在内部组织的均匀化、晶粒的尺寸与形状、点缺陷与线缺陷浓度变化等铸造缺陷方面模具模具铝板，均获得显著改善，使铸态组织转变为变形组织，大大提高了金属的加工工艺性能。特别是在深冲性能方面，热轧料有着铸轧料不可比拟的优势。铸轧法的特点：铸轧板的内部组织属于半铸态结构，晶体的方向性较强。与热轧相比尴尬局面，具有投资少、成本低、效率高的特点。
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.　　
　　
模具济南铝板http://www.jngdly.com/是指用铝及加工而成的板型材料，合金模具济南铝板还可以分为冷轧和热轧最低增速模具模具铝板，主要区别是以阳极氧化为区别模具模具铝板，热轧模具济南铝板可以做阳极氧化。冷轧模具铝板和热轧模具铝板用途不同迅速蔓延，冷轧模具济南铝板多用于模具类，热轧模具铝板适合冲压拉伸方面。同样的材质由于制作工艺不同，它的物理性能相差很大。又被称为塑性成形，按铝材在变形过程中的受力与变形方式（应力—应变状态）分为：铸造、锻造、挤压、旋压、拉拔、轧制、成形加工（冷压、深冲）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.
