通常，轮毂的铸造过程 分为重力铸造，低压铸造和旋转铸造。
Gravity casting, a wheel making process that is on the verge of extinction. It mainly fills the entire wheel mold with the weight of the molten liquid aluminum itself, and then cools down to form. This kind of wheel has a higher yield and a lower mold cost, but it has disadvantages. It is also obvious-it is difficult to control the flow time of the metal liquid, because the metal liquid in the slow flow process will inevitably cause the metal temperature at the end far from the casting port to be lower. At this time, the stable temperature control of the mold becomes very important. Too high or too low will affect the manufacturing quality of the hub; however, in order to prevent premature solidification, the temperature of the molten aluminum needs to be increased, but it is easy to cause uneven molecular distribution and more sand holes. At this time, in order to maintain The strength must be filled with more aluminum water, so the weight of the finished wheel cast by gravity will increase.
Anxious to reduce the weight of the wheel hub today, the traditional gravity casting process cannot meet the discerning demands of car owners. Besides, each wheel wheel can reduce the weight of 1KG, which is equivalent to reducing the vehicle weight by 15KG. The weight of an adult will reduce fuel consumption if "one less person rides".
Low-pressure casting, which is based on gravity casting, uses low-pressure nitrogen to "accelerate the speed of advancing the liquid aluminum filling mold" for liquid aluminum. At the same time, there are fewer bubbles, and the distribution is more uniform, and the metal structure is more compact. Better performance. Although under the action of low pressure, the density of the wheel hub has become higher, but the distance from the goal of light weight is worse than that, but there are also "exceptions". The low-pressure cast wheels under the MMX brand use material optimization forces and structural strengthening forces. With outstanding design power, it has reached a high level of strength and light weight.
Spinning process, in the strict sense, is also a branch of "casting". The wheel produced by the process includes two different technologies: "spinning" and "casting". First, the "low pressure casting" method is used to produce the disk surface shape and the rough rim rough. Before this step, it is compared with ordinary casting. The method is exactly the same. The rough embryo produced looks like a shorter wheel hub, while the inner rim is thicker and looks shorter and fatter.
接下来，必须将胚胚送入加热炉并加热到约400度的高温。因为尚未达到铝合金的熔融温度，所以粗糙的铝合金保持固态，但是稍微软化以进行加工。温度和“旋转”是利用高压辊子将轮辋的粗糙胚压向侧面延伸，简单来说，“旋转”的原理就像“用手拉陶瓷胚”，同时旋转时，侧面施加压力以拉伸并变薄铝合金毛坯。由于重新成形铝合金的高压，在加工过程中可以增加铝合金的密度，这使得铝合金的内部晶体结构更加紧凑。该方面类似于“锻造”。高压加压以增加金属密度的原理是相同的。由于金属材料更坚固，因此轮圈体更轻更薄可以满足强度要求。
车轮除了性能外，还有另一个主要功能-如何结合耐用性和强度？作为出色的轻质轮毂，不仅需要重新设计中心盘表面，而且还将减小内，外J型截面以及轮辋体的厚度。就像MMX拥有的高端纺车品牌Jihoo一样，它使用MMX的浓缩纺丝成型技术。感应炉预热后，轮坯通过连续的高速旋转运动而动起来，以高速动员。在高挤压力的作用下，以凝结的形式移动胚部分。在纺丝过程中，轮辋毛坯变薄和变长，这改变了轮辋的金属内部结构，从而内部分子以较高密度的纤维形式排列。因此，与普通铸轮相比，具有更高的强度和更高的韧性。此外，旋转的轮辋的截面更薄，因此减少了轮毂的总重量，这是Jihoo纺丝工艺最直接的技术优势。
但是，轮辋的厚度与载荷成正比。轮辋厚度越薄，负载越小。因此，在不减少材料的施加并且在保持高强度性能的同时减轻轮毂的重量的情况下，增加了总负荷。一级，这称为能力。但是，通过技术优化，Jihoo的车轮负载能力以725KG（1600磅）为起点，四个车轮的总负载能力高达2900kg。
Jihoo纺车轮正在解决“高强度，轻量”矛盾的谜团，这是在早期阶段优化材料性能并增强机械结构的方法。三种纺纱产品的轮辐设计不同，但是它们都继承了相同的家庭设计语言和优化的机械结构。例如：加强内/外J部分的厚度不均匀结构，以改善车辆的动态稳定性。轮辋上的肋条设计在更大程度上保护了车轮的圆度，并提高了车辆的安全系数。通过优化弧度数据，强调力学和美观性的纵向结构减少了车轮滚动变形的量，减少了金属疲劳，
反映轮毂的高质量以及满足标准要求的车轮机械性能的要求，Jihoo车轮系列采用了更严格的mms标准并通过了六项性能测试，以进一步提高每个测试极限，从而进一步提高了车轮的抗疲劳性和抗疲劳性。冲击性能提高了Jihoo车轮产品的安全性。对于使用较大车轮或低空转比轮胎的车主，最常见的问题是车轮在穿过坑洼或撞击时变形。为了避免这种情况，有必要加强这一过程。Jihoo使用强大的技术优化力，提高轮毂的抗冲击性，减少轮毂变形的可能性并大大提高行车安全性。如果要查看更多的车轮，可以单击 中国车轮。
