When we look at the making of a sand table model, we will see the structure of the sand table as a whole. The shortcomings of each place will affect the overall effect. Just like a bucket of water, only when the height of each board is the same, can it be well filled with water. If one of the boards is short, it will affect the water content of the whole bucket.

而底盘的制作也是如此，如果底盘的制作的不好，别的部位做的再好，也会影响整体效果。下边我们将给大家介绍下沙盘模型制作中的底盘。

And the production of chassis is the same. If the production of chassis is not good, no matter how good the other parts are, the overall effect will be affected. Next, we will introduce the chassis in the production of sand table model.

我们经常看到沙盘模型制作，但是它的底盘是什么材料做的，你留意过吗？你一定会说是木头的或者是塑料的，其实你答对了一半。

We often see sand table model making, but what material is its chassis made of? Have you noticed? You must say it's wood or plastic, but you're half right.
              

沙盘模型的底盘通常是由PS板、KT板和木质底盘做的，还有天然石材、玻璃、石膏等。PS(聚苯乙烯板)与KT板具有质地轻、任性好、不变形等优点，是普通纸材模型的俱佳材料。然而，成品PS板和KT板的切面难以磨平整，需要应用厚纸板、瓦楞纸或者其他装饰型材封边处理，保持外观光洁。

The chassis of sand table model is usually made of PS board, KT board and wooden chassis, as well as natural stone, glass, gypsum, etc. PS (polystyrene board) and KT board have the advantages of light texture, good willfulness, no deformation and so on. They are both excellent materials for ordinary paper models. However, it is difficult to smooth the section of finished PS board and KT board, so it is necessary to use cardboard, corrugated paper or other decorative profiles for edge sealing to keep the appearance smooth.

底盘是沙盘模型的重要组成部分，它对主体模型起支撑作用。平整、稳固、宽大是模型底盘制作的基本原则，在具体制作中还要考虑沙盘模型的整体风格、制作成本等因素。木质底盘质地浑厚，一般会保留原始木纹，或在表面钉接薄木装饰板，装饰风格要与沙盘模型主体相衬映，板材边缘仍须钉接或者粘贴饰边，避免底盘边角产生开裂。

Chassis is an important part of sand table model, which supports the main model. Flat, stable and wide are the basic principles of the model chassis production. In the specific production, the overall style and production cost of the sand table model should also be considered. The wood chassis is thick in texture. Generally, the original wood grain will be retained, or the veneer decorative board will be nailed on the surface. The decorative style should be matched with the main body of the sand table model. The edge of the board still needs to be nailed or pasted with trimming to avoid cracking at the edges and corners of the chassis.

无论哪种材料的选择，都是为了使沙盘模型的底盘起到装饰效果，衬托起整个沙盘模型。底盘做的好，不仅会使整个沙盘模型显得高大上，还会为整个沙盘模型起到锦上添花的作用。

No matter which material is selected, it is to make the chassis of the sand table model play a decorative effect and set off the whole sand table model. A good chassis will not only make the whole sand table model look tall, but also make the sand table model more beautiful.
