First, manual processing.
Manual processing is the most basic and common method of processing hand boards. It mainly depends on the manual skills of workers, through manual cutting, bending and polishing, to make materials into the required shapes and sizes. The advantages of manual machining are low cost, high speed and high flexibility, which can meet the needs of different shapes and sizes without any special equipment and technology. However, the precision and consistency of manual processing are low, which can not meet the demand of high precision, and it also requires technicians to have certain manual skills and experience.
Second, the numerical control processing
Numerical control machining refers to the way of controlling machining machine tools to process through computer programs. CNC machining can achieve high precision machining, and at the same time, due to program control, it can also achieve automatic machining to a certain extent, which improves production efficiency. Numerical control processing can also process complex shapes, and the processing speed is faster than manual processing. The disadvantage of NC machining is high cost, which requires professional NC machining equipment and technology, and also requires designers to have certain computer programming ability.
Third, 3D printing.
3D printing is a processing method of making physical models by overlaying materials. 3D printing has the advantages of high manufacturing speed, low manufacturing cost, high production efficiency and seamless connection. At the same time, 3D printing can also achieve complex shapes and internal structures, which can meet different design requirements. The disadvantage of 3D printing is that the surface of the printed model is rough due to the lamination manufacturing method, which needs subsequent treatment and polishing.
Fourthly, the vacuum compound mold.
Vacuum replication is a processing method to make a physical model by making a mold, putting materials into the mold and heating and compressing them under vacuum. The vacuum compound die has the advantages of high manufacturing precision, good appearance quality and mass production. The disadvantage of vacuum replication is that it needs to make molds, and the cost is relatively high, which is only suitable for some products with specific shapes.
Verb (abbreviation of verb) jet molding
Injection molding is a processing method of injecting molten plastic into a mold, cooling it and taking it out to make a physical model. Injection molding has the advantages of fast manufacturing speed, low cost and mass production. At the same time, injection molding can also achieve high-precision machining, and can produce complex shapes and internal structures to meet different design requirements. The disadvantage of injection molding is that it needs to make molds, the cost is relatively high and it is only suitable for plastic materials.
The steps of injection molding include:
1. mold design: designers need to design molds that meet the requirements according to product requirements, including mold shape, size, material, etc.
2. Mold making: The mold maker can make molds according to the design drawings, and can use CNC machining and EDM machining.
3. Injection molding: the molten plastic is injected into the mold, cooled and molded, and finally the mold is taken out to obtain the product.
4. Post-processing: Post-processing the product, such as deburring and polishing.
