Molding manufacturing technology can be used not only in functional testing, but also in product conceptual design, and also in mold design and manufacturing. It is also widely used in the fields of medical treatment, household appliances, automobile and handicraft production.
Rapid tooling manufacturing
The solid model generated by molding manufacturing technology can be used as mold sleeve or mold core. Combined with electrode grinding, powder sintering, precision casting and other technologies, the functional mold required by products can be rapidly manufactured. Moreover, the manufacturing cycle of the mold is not long, and only 20% or 10% of the time can be manufactured by using the traditional CNC cutting method The more complex the mold, the more obvious the benefit of this technology.
Product design evaluation and functional testing
Molding manufacturing technology can change CAD model or drawing into solid model in a few hours or days, which can shorten the period of trial production and improve the quality of design. In the product design evaluation and function test, the feedback information of the user to the design can be quickly obtained by using the molding manufacturing technology [7]. In addition, the use of this technology in the manufacturing industry can facilitate the product manufacturer to deepen the understanding of the product, and reasonably determine the process flow, production mode, cost, etc. Compared with the traditional model manufacturing, the molding manufacturing technology has higher precision and faster manufacturing speed in the production process of the product. The manufacturer can modify and verify the product at any time through the CAD model, which can make the product design more perfect.
Medical bionic manufacturing
The combination of medical CT diagnosis technology and molding manufacturing technology can not only copy the shape of human organs or bone structure, but also preview the operation plan, and the technology plays an active role in the design and manufacture of artificial limbs. In medical bionic manufacturing with the help of molding manufacturing technology, a biodegradable material is made into a three-dimensional prototype by rapid prototyping equipment, and then the biological growth factor is implanted into the prototype. Through the culture of culture medium, the degradable material can be replaced by organisms to form bioactive tissue structure products It has beautiful appearance and biological activity, which can provide a new technical way for the treatment of prosthesis replantation.
Precision casting
There are several main situations when applying molding manufacturing technology to precision casting: first, investment manufacturing. The traditional wax pattern manufacturing process uses wax prototype, but in precision casting, using molding manufacturing technology, under the role of rapid prototyping equipment, wax pattern can be directly produced, and at the same time, wax pattern can obtain engine shell parts. Second, manufacturing precision casting shell. The direct membrane shell method mainly depends on the forming technology. During the molding process of the mold shell, there is a layer of alumina powder on the surface of the worktable, and its thickness is the same as that of the CAD model. At this time, the silica gel is sprayed out with a micro nozzle to form a 2D profile. The aluminum powder contacted with the silica gel will be bonded together, and the workbench will drop a layer of height, and a new layer of aluminum oxide powder will be laid on it There are new aluminum powders bonded together so that the model can be formed under layers. This kind of manufacturing technology can obtain the precision casting shell, and promote the further development of the precision casting process.
Product master mold
In the past, the method of removing materials was used in the manufacturing of product master mold, which requires high processing technology and takes a long time. It will not only waste raw materials, but also cost more money. The above problems can be solved by using molding manufacturing technology in the manufacturing of product master mold. In this way, the wood mold for sand casting can be replaced by rapid prototyping parts, so that the complexity of the product master mold can not be limited by the structure of processing equipment. In a word, the use of molding technology in the manufacturing of rapid and economical turnover mold has obvious advantages and can improve the manufacturing efficiency.
The manufacture of artworks
Architectural ornaments and artworks are conceived and designed according to the inspiration of designers. In traditional industrial production, artwork needs to be copied on the drawings and the basic model can be established before the sample of finished products can be produced. This not only consumes time and manpower, but also appears due to the error between the actual and the drawing design The proportion of finished products is not coordinated, which increases unnecessary processing procedures and causes waste of cost. The application of molding manufacturing technology in art manufacturing can bring positive effects. It can not only accurately present the design data of artworks, but also shorten the forming time of artworks, and bring certain benefits in various aspects of cost. Even if the external structure of the artwork is complex or the inner shape of the artwork requires high material requirements, it can also achieve production and ensure the quality of production. According to the art design prototype, and with the help of computer technology and design software to calculate the relevant data of artwork, designers can easily make samples anytime and anywhere. In addition, art designers can also transmit relevant data of art design to manufacturers or production workshops through network platform or information technology, so that manufacturers can quickly receive data and shorten the time consumed in product production. At the same time, it is also conducive to communication between designers and production personnel, and timely find and solve problems, which can ensure efficiency, It can guarantee the quality. This can not only speed up the production time, but also maximize the avoidance of errors, improve the efficiency of art production, reduce the cost of waste.
