Introduction to three methods of making sand table models
There are many requirements for making the sand table model. The requirements for making this model are very strict, and no grass or tree can be flawed. Therefore, in the production stage, it is necessary to master various methods and understand the advantages and disadvantages of various methods to ensure that the produced model can look good and beautiful. For this product Witkey, introduce three methods of making sand table models. Anyone who is interested in making sand table can learn about it.
The first is the low-power model. The design requirements are generally proposed by the managers and users of the sandbox model according to the specific application of the sandbox model. In the business model, demand comes from real estate developers and investment owners. They will set requirements based on years of accumulated business experience and market conditions, generally pursuing display effect, production efficiency and low price.
1. Machining is to use cutting and forming machines to process specific sand table model materials, greatly improving the accuracy of the sand table model, and improving the work efficiency by leaps and bounds. Machining requires a special operation room. After a board is processed, the leftover material basically loses its reuse value, and the production cost is high. In addition, processing is limited to the use of special plates matching with mechanical tools, resulting in a single form of sand table model. If you want to add decoration, you must make it by hand.

2. The basic method of making sand table models by hand, give full play to the creativity of designers, and use a variety of materials for comprehensive processing. Handmade tools are relatively simple, mainly based on paper cutters, scissors, glue, triangular ruler and other basic tools. Scissors, pasting, fixing and painting technology can meet the production requirements in most cases. Handmade sand table models have various forms, but their accuracy is not high. The production methods vary from person to person, making it difficult to carry out large-scale commercial display of sand table models.
3. Cam assembly cam is also called computer aided manufacturing. Its core is computer numerical control (CNC), which is a system that applies computer to production process. The characteristic of numerical control is that the machine tool is controlled by program instructions encoded on perforated paper tape. The machine tool can automatically select tools from the tool magazine and automatically change the working position. It can continuously complete multiple processes such as tool grinding, drilling, torsion, tapping, etc. These processes are controlled by program commands, and the processing technology can be changed by changing the program commands.
At present, CAM manufacturing is being promoted in the field of sand table model manufacturing. First, the computer draws a linear graph and determines the size. Then transfer the graphic box to the CNC engraving machine or cutting machine to automatically cut the sand table model board. After Z, the plate can be simply assembled. Intelligent cam is different from ordinary machining. It is controlled by a computer. In the process of carving and cutting, the model maker does not need to contact the plates and props, which greatly improves the safety and accuracy. To make a commercial sand table model, we should grasp the key points and select certain methods in the design to ensure the effect.
