3D printing conformal waterway design application
The advancement of science and technology drives all kinds of products to flourish, and the development cycle of products is relatively shortened. In order to increase the mass production value in a limited time and at the same time take into account the quality of the products, the mold can be reduced by reducing the cooling efficiency in the molding cycle. Important steps in the molding process. The traditional method of fabrication is limited by the existing technology by drilling or cutting the mold. The construction is very complicated and the life of the mold may be shortened due to reworking. After the emergence of metal 3D printing , these problems have been improved! The use of metal laser sintering technology (SLM) can make up for the inadequacies of CNC machine tools and EDM machines, not only to improve mold capacity, but also to reduce material consumption and process time.
Application Case 1: Industrial Mold
Conformal waterways are more difficult to process due to their geometric complexity than traditional waterways. The traditionally designed cooling waterway is completed by drilling. The straight and round tubular shape has to avoid the structure or the original assembly, so the waterway design is extremely limited, and there is often no coolant in the hot spot. However, if metal laser sintering technology (SLM) is used, there is no processing limitation. In addition to being closer to the product outline, and providing good heat dissipation efficiency for the dead corner or the area where heat is not easy to heat, the cooling cycle is reduced. Because the mold temperature difference is reduced, some defects such as warpage and dent can be effectively avoided, so the product quality Can be improved.
Application Case 2: Moore Core
The cooling water circuit is designed in the form of fan blades to maximize the cooling efficiency. It can be seen from the profile temperature of the mold base that there is heat accumulation in the groove area of ​​the product, which is because the water path in this area is difficult to extend into the cooling. From the temperature distribution of the water pipe, it can be seen that the temperature difference between the inlet and outlet of the water pipe is about 1 °C. However, since the water path surrounds the copper sleeve, it helps the heat dissipation of the copper sleeve, and the copper sleeve takes away the heat of the partinsert, thereby contributing to the temperature drop in the axial region. From the temperature map of the waterway design, the high temperature in the axial region drops to 143 °C.
The model prototype output has a certain market potential value. Compared with the shortcomings of the traditional model, the 3D printing technology can bring a lot of convenience to the demand unit. Dexter Technology's internal 3D printing equipment, with a technically experienced engineering team, provides customized solutions for printing complex features and precision parts! From scanning, special part design/reproduction, proofing, evaluation and confirmation, and finally production output, reducing design constraints, development time is shortened, making it easier for R&D units to develop products with market advantages.
In addition, when the conventional process is made for complex features, it is prone to thermal deformation and affects the process yield. Looking at the advantages, 3D printing design prototype output can break all design constraints. Dexter Technology uses metal 3D printing technology to make it easier to create complex internal structures, eliminating casting and soldering steps and reducing weight and complexity. Effectively improve manufacturing quality.
