一、尺寸数据的搜集与制图

1、 Collection and drawing of dimension data

航天模型公司在进行航天模型的制作时，往往需要进行预先的航天器材的数据搜集与CAD图的绘制工作。在进行神州系列载人发射器的模型制作过程中，就需要对于推进器、管体长度、系统体积、头锥尺寸等进行搜集。之后还有进行CAD制图，之后才能交付航天模型公司的生产加工进行生产。

When aerospace model company makes space model, it often needs to collect data of space equipment and draw CAD drawing in advance. In the process of making the model of Shenzhou series manned launcher, it is necessary to collect the propeller, tube length, system volume and cone size. After that, CAD drawing can be carried out before being delivered to aerospace model company for production and processing.

二、材料的选择与预制作

2、 Selection of pre fabrication materials

航天模型公司在进行模型参考件的尺寸搜集与图形绘制工作之后，需要进行相关比例下的尺寸缩小，之后可以将带有尺寸比例的元件图交由航天模型公司的生产部门进行样品的制作。样品制作结束后的航天模型样品要经历进一步的尺寸复查，保证测量数据的准确性。

After the size collection and drawing of the model reference parts, the aerospace model company needs to reduce the size under the relevant scale. After that, the component drawing with size scale can be submitted to the production department of aerospace model company for sample production. After the completion of the sample production, the space model sample should undergo further dimensional review to ensure the accuracy of the measurement data.

三、产品的正式制作

3、 Formal production of products

航天模型公司在确认过样品之后，会进行产品的正式制作，这其中包括对于航天模型所用材料的选择，为了保证航天模型的质量，一般会采用较为接近实际材料质感的金属材料进行航天模型主体的制作。其次还要考虑模型的整体质量，航天模型公司制作的产品会在质量上与尺寸上尽可能按比例还原实际型号。

After confirming the samples, the aerospace model company will carry out the formal production of the products, including the selection of the materials used for the space model. In order to ensure the quality of the space model, the metal materials which are close to the actual material texture are generally used to make the main body of the space model. Secondly, the overall quality of the model should be considered. The products made by aerospace model company will restore the actual model in terms of quality and size as much as possible.

航天模型公司的产品制作包括航天模型尺寸的确定、模型样品图的绘制、模型样品的制作、航天模型的材料选择、航天模型的正式制作五个步骤。在航天模型公司制作实际产品时，对于模型的尺寸不断复查是十分关键的，这样才能保证航天模型生产公司产品的质量。

The product production of aerospace model company includes five steps: the determination of space model size, the drawing of model sample diagram, the production of model sample, the material selection of space model and the formal production of space model. It is very important to review the size of the model when the aerospace model company makes the actual products, so as to ensure the quality of the products of the aerospace model company.
