铜大缸在现代主要是当作风水铜缸摆放在院子中的，那铜大缸厂家是如何铸造铜大缸的呢？铸造铜大缸需要哪些步骤呢？

In modern times, copper cylinders are mainly placed in the yard as geomantic copper cylinders. How do copper cylinder manufacturers cast copper cylinders? What steps are needed to cast the copper cylinder?

1.设计产品图片：按照顾客的要求找专业人员设计产品图片

1. Design product pictures: find professionals to design product pictures according to customer requirements

2.泥塑制作：根据设计出来的图片样子用泥稿做出个大致的模型出来，方便我们定型，如果有什么不好的地方我们可以在泥塑上改动，在其次就是按比例放大泥塑，进行一比一的泥塑制作。

2. Clay sculpture making: according to the designed picture, make a rough model with the clay manuscript to facilitate our finalization. If there is anything bad, we can change the clay sculpture. Next, we can enlarge the clay sculpture according to the scale and make the clay sculpture one to one.

3.模具翻制：模具一般有两种：一种是石膏翻制，一种是硅胶翻制，我们在不太复杂情况下就用石膏翻制，反之就用硅胶翻制。

3. Mold remaking: there are two kinds of molds: one is gypsum remaking and the other is silica gel remaking. We use gypsum to remake when it is not too complicated. On the contrary, we use silica gel to remake.

4.蜡型灌制：把融化好的石蜡灌到已经制作好的石膏模具或硅胶模具里，等石蜡冷却后就成了蜡型了。

4. Wax mold pouring: pour the melted wax into the prepared gypsum mold or silica gel mold, and the wax will become a wax mold after the wax is cooled.

5.制壳：制壳和模具翻制一样有两种：一种是精密铸造，一种是树脂砂箱制作。

5. Shell making: there are two kinds of shell making and mold turning: one is precision casting and the other is resin sand box.

6.铸造和打磨：在高温环境下把铜化成铜水灌注到做好的壳或砂箱里面，然后再进行清冒口打磨。 

6. Casting and grinding: under high temperature environment, copper water is poured into the prepared shell or sand box, and then the riser is cleaned and polished.

7.表面作色：一般铜大缸都是一体成型的，所以打磨好就可以上色了。

7. Surface coloring: generally, large copper cylinders are integrally formed, so they can be colored after polishing.

8.上油、封蜡：表面作色完后，接下来就是对其上油、封蜡了，上油、封蜡可以让铜大缸长久保持最新。

8. Oiling and wax sealing: after the surface is painted, the next step is oiling and wax sealing. Oiling and wax sealing can keep the copper cylinder up-to-date for a long time.
