A multi-machining of mold manufacturing process - with DMLS technology, processing technology and high-speed 5-axis EDM EDM technology in a seamless automated continuous production process to produce the corresponding cooling mold.
When it comes to injection mold and blow mold tooling design and manufacture, the higher the level of cooling, the better its performance, the cooling channel can control the mold temperature is kept in check state. Optimized cooling channel can improve the quality of the mold, to extend the life of the mold, molding to improve the overall efficiency.
However, some mold out of shape, it is impossible to optimize mold cooling channels. For the production of golf cylindrical mold can be used as a perfect example. For the mold, the mold cooling channels in the best shape of the equivalent cylindrical mold cavity mirror, or with the cylindrical shape of the mold cavity is consistent.http://www.prmindustry.com/Abstract...Articles section For the production of such a cooling channel mode, using the traditional processing methods difficult to meet the technical requirements. In essence, only the selected point of the hole is the only option. However, due to adopt a multi-process machining of the mold, it will direct laser sintering (DMLS) technology, high-speed 5-axis machining and EDM technology combined to make production of the corresponding cooling the mold to become a practical continuous process automated production processes.
This production process chain run, from design to finished product manufacturing process is actually continuous. In this process machinery and equipment used in a network connection, a 3D CAD model by the same operation and running, has been from beginning to end, not only improve accuracy, reduce setup time. Mold maker can basically work from a 3D model, and around it to create a mold plug-in, it is perfectly consistent with the position of the cooling channel.
Corresponding cooling the mold has been well established, and has many high-end manufacturers to reduce production cycle time by up to 40%. DMLS technology that uses molds to improve product quality and prolong the life of the mold, and optimize the cooling effect, but also improve the efficiency of the molding process. For mass production, the time and it saves costs and energy saving effect is considerable.
Those who profit from the DMLS technology mold manufacturer, with a corresponding cooling channel manufacture of molds, so they have many success stories. However, in a production chain, high-speed milling and EDM EDM combination of methods, allowing DMLS technology easier to implement, especially those engaged in mass production injection mold and blow mold operations especially manufacturers.
In multi-machine production process chain, DMLS system created with the corresponding full set of mold cooling channels and subsequent stages of processing all the necessary fixtures. Then, the mold production process chain will be transferred to the second part, which includes high-speed machine tools and EDM EDM process, whether it is mold cutting machine tools, machine tools or wire type.
DMLS technology is a significant advantage is that it can produce a nearly one-time operation of the network components, the second part has yet to finish production. Then a single fixture systems, secondary operations, reduce the amount of manual work fitter to ensure that the surface finish to maintain the accuracy of the 3 ~ 5μm level. The reduction process by reducing the number of mold in the manufacturing process involved the gradual operation of law, this approach started from a block of raw material production, so that the scrap rate to the lowest level.
DMLS technology to make the part surface finish machining excellence, high-speed milling machine will be sent to die on the parting line without flash (no leaks) surface machining, mold and other surface precision machining. Then sent to die on the EDM EDM, like high-speed milling machine as using the same fixture clamping mold, the mold cavity within the precision machining. Then using a wire EDM to cut off the mold fixture, this time, the mold can be readily used for actual production. In the mold production process, all operations, including DMLS technical processing, 5-axis high speed milling and EDM will run simultaneously. Group for pallet workholding help reduce the overall process of time plays a key role.
For some geometry, the processing machinery in DMLS fixture with a dedicated solution that ensures the future of the correct positioning of parts manufactured. Thus, to achieve two basic objectives: to ensure the accuracy and base parts parts easily transferred from the high-speed milling machines to EDM discharge.
DMLS processing technology and high-speed milling and EDM EDM combined, not only to ensure accurate mold components from one processing by another processing technology, but also help to improve the mold cooling channels and the corresponding components of the overall production characteristics. As more and more mold manufacturers using these optimized cooling channel, so this can provide a continuous integrated process automation systems and more demand will continue to increase.
