Metal powder Laser modeling composite processing technology can be one-time and integration to complete processing a profiled internal waterways and exhaust functions. It is integrated with materials technology, computer software technology, laser technology and CNC machining technology. It can effectively reduce the mold cooling time, improve product yield and reduce development costs.
Composite processing technology of metal powder integrated compact laminated molding process of metal powder selective laser melting with the traditional high-speed machining process. It is a compound processing technique with a laminated shape and removing the opposite direction. It integrates with materials, technology, computer software technology, laser technology and CNC machining technology. The past simple metal powder selective laser melting than laminated modeling technology, which is characterized once and integration to the completion of processing with internal the profiled waterways and exhaust function, but the shape of the surface complex, difficult to implement the subsequent processing of precision mold parts. Processing dimensional accuracy of 0.005mm, material hardness after heat treatment can be achieved Hrc54. Resulting from the processing of mold parts can be extremely effective in shortening the manganese powder mold cooling time, eliminate trapped air within the mold, to improve injection molding efficiency, and improve the purpose of the plastic parts quality.
Characteristics of metal powder compact composite processing technology: it can create extremely complex and close to the finished surface of the waterway designed mold cooling water through the forming of metal powder sintering is also called shaped waterway, the cooling water channel as the product with the and change. With the shaped waterways advantage is balanced cavity temperature, speed up the mold cooling time, shorten the mold cooling time at the same time improve the quality of plastic products.
At the same time, the metal powder compact shape of composite processing technology can be one-step processing of precision mold parts to improve the efficiency of the molding. In the face of complex mold cavity, the traditional processing methods after the first rough machining center, and then finishing, encountered in the copper powder(FCu) processing center can not be processed in place, the traditional approach is through the demolition of the electrode, then the electricity spark to processing. Metal powder compact modeling of composite laminated molding process and the traditional high-speed machining process integration can process step out of the cavity of arbitrary shape, to avoid the traditional EDM.
It also can measure the cavity internal exhaust and can be applied to gas-assisted injection molding. Mold venting plays a crucial role in the mold injection. Bad exhaust will directly lead to the surface of the product burns or incomplete products due to trapped gas. Metal powder compact modeling composite processing technology can make within the cavity exhaust system and directly leads the gas in the mold cavity to external injection.
