汽车模型的各个部件都是浇铸出来的，浇铸就需要金属模具。汽车模型厂里会有专门的车间生产金属模具。他们根据石膏的模型，使用机床加工模具。这个车间犹如所有的机械加工厂一样，一进入就会感到滚滚热浪，金属的撞击声、旋转的刀具发出的切削声不绝于耳。这是一个让人不愿意多呆的地方，但是工人们依然默默的在自己的岗位上，为每一个精美的车模流着汗水。

The various components of a car model are all cast, and casting requires a metal mold. There will be a dedicated workshop in the car model factory to produce metal molds. They use machine tools to process molds based on gypsum models. This workshop is like all mechanical processing plants, and as soon as you enter, you will feel a rolling heat wave. The sound of metal impact and the cutting sound of rotating cutting tools cannot be ignored. This is a place that people don't want to stay much, but the workers still silently sweat for every exquisite car model in their posts.

和真车生产一样，汽车模型也要先生产零件，再进行组装。一般零件的材料有两种——合金金属和塑料。这些零件都是靠一种被香港人称为“啤机”的机器来生产，不过它可不是酿造啤酒的机器，而是塑胶注塑机和金属压铸机之类的机器。铸出来的合金件外表会很粗糙，要经过打磨处理后，才能外表光华。他们发出略黑的金属光泽，在阳光下很好看。塑料件的加工相对容易，不需要更多的处理。

Just like real car production, car models also need to produce parts first before assembly. There are two types of materials for general parts - alloy metal and plastic. These parts are all produced using a machine called a "beer making machine" in Hong Kong, but it is not a machine for brewing beer, but rather a machine for plastic injection molding and metal die-casting. The surface of the cast alloy parts will be very rough, and they need to be polished before they can have a shiny appearance. They emit a slightly black metallic luster and look great in the sunlight. The processing of plastic parts is relatively easy and does not require further processing.

汽车模型零件的做工直接影响到整体质量，尤其是一些能开启的部件，例如：车门、行李厢之类，这些零件的尺寸精度要求是很高的，否则在开闭的时候会有松动现象发生。另外金属镀件的光亮程度，仪表板的粘纸等也很重要。

The workmanship of car model parts directly affects the overall quality, especially for some parts that can be opened, such as car doors, luggage compartments, etc. The dimensional accuracy of these parts is required to be very high, otherwise there will be loosening when opening and closing. In addition, the brightness of the metal plated parts and the adhesive paper on the dashboard are also important.
