When building a model, the first step is shaping. This step is very important, just like the foundation of a building. The quality of mold forming is directly related to the effect and quality of the final mold forming. What are the methods of building models? The mold maker will tell you.
First, direct casting method
If the shape of the sand table model cannot be cast in one shot, the general shape can be cast in advance, and then the performance and details of the model are continuously refined until the final completion. Turning forming method: If a regular circle or basic shape is formed, it can be formed by turning a workpiece machine. After turning, they can be connected, trimmed, and detailed until the desired effect is achieved.
2. Template scraping forming method
This general model is suitable for the scraping forming method of color templates with laterally changing shapes. Rough mold forming process: For more complex shapes, similar rough molds can be made with clay or sculpted clay, and then negative molds are made with the rough mold. The mold can be casted, and finally the building model can be finely processed.
3.Skeleton casting process
When making a large-scale model, in order to ensure the strength of the model, reduce weight and facilitate transportation, you can fill the inside of foam plastic or other materials when making the mechanical model. It is necessary to tie a wooden frame in advance according to the modeling characteristics, or choose other materials that can ensure strength and are easy to process.
