Hardware Network HC: Seamless welding technology Mold Demonstrated excellent welding performance, improved part accuracy, finish and appearance of the observability, reduced
Mold The manufacturing cycle. As the global market demand for high-quality components increasing, people can improve part accuracy and seamless welding technology more and more popular. Recently, Japan Makino Inc. (Makino) coalition partners successfully developed a new type of seamless welding technology, which can effectively eliminate the seam between mold, transfer line and parting lines. The key to this process using advanced technology and vertical machining centers can be used in new ways to produce molds, while injection molding process, the use of a highly efficient heating and cooling cycle. This new technology is not yet patented, Makino for its development of related processing applications.
Using seamless welding technology can not only help eliminate mold seam, but also a corresponding increase part accuracy, finish and appearance of observability. At the same time, seamless welding technology in injection molding process of implementing a highly efficient control, shortening the processing cycle of the mold. As the technology products with excellent surface finish, so do not need to use secondary plating and annealing, thus avoiding the contraction caused by the size of secondary changes. This technique applies to most of the plastic resin and glass-filled materials, particularly suitable for automotive instrument panels, laptop computer case, TV and digital camera processing devices such as shell, is also applicable to large-scale display devices and automotive exterior parts processing.
New mold seamless welding technology Mold production technology in the past, the cooling lines near the surface arranged in the mold, the product is not always uniform surface finish. In some relatively new technology, through the mold core and cavity cooling water pipeline set in the resin near the injection region, can produce a better product quality assurance.
New seamless welding technology used in modern machine tools and some new technology. According to the new technology, process requirements, processing similar to the mesh of the mold core and cavity, in order to prevent its movement and the second fixture, use the fourth-axis milling machine, this can increase the tolerance of dimensional precision. Board room cooling fins, and water pipelines are more widely used, and further improve product quality and seamless weld finish.
Manufacturing process of the mold
Emergence of new welding technology to enable seamless die channel design changes and use a variety of facets of vertical machining center milling possible. Forming in the actual molding process, the die channel design changes can help control heating and cooling of the best mold temperature. In diameter through the important infiltration of milling rooms, you can keep the temperature fluctuations within 60 . The infiltration chamber was in the back cavity milling, the same shape and mold cavity can be used as high-pressure steam and cooling water channel, could play the role of cavity surface thermal conductivity, so that a more uniform temperature distribution, so as to maintain temperature control rate of temperature fluctuations.
