第一步：做泥稿，按着甲方标准尺寸做出1:1的泥稿模型。

Step 1: make the clay draft and make a 1:1 clay draft model according to the standard size of Party A.

第二步：模型做好后在模型上敷上石膏，待石膏凝固后扒下。石膏必须用好石膏。不然石膏力度小，容易碎。直接影响铸铜效果。石膏扒下的时候必须完好无损。

Step 2: after the model is completed, plaster the model, and then peel it off after the plaster solidifies. Gypsum must be used well. Otherwise, the plaster strength is small and easy to be broken. The effect of copper casting is directly affected. The plaster must be in good condition when it is removed.

第三步：在石膏上刷上石蜡，石膏上的石蜡就是控制铸铜的厚度，（如石蜡厚度1cm那铸铜厚度就是1cm）

Step 3: Brush paraffin on the gypsum, the paraffin on the gypsum is to control the thickness of copper casting (for example, if the thickness of paraffin is 1cm, the thickness of copper casting is 1cm)

第四步：铸造分3种铸法。精铸法，小件的还可以。大件铸出来容易变形。

The fourth step: there are three casting methods. Precision casting, small pieces are OK. Large parts are easy to deform when cast.

沙铸法。沙铸法工艺好，不走形是大件的理想选择。

Sand casting method. Sand casting process is good, not out of shape is the ideal choice for large pieces.
