61Trends in the packaging industry indicate that green packaging and technological innovation are important directions for the future. The application of two-color injection molding machines is in line with this trend, as it can reduce the use of materials and improve production efficiency, while producing more attractive and functional packaging products. As technology advances and market demand grows, the application of two-color injection molding machines in the packaging industry will become more widespread.
KraussMaffei Technology Center has launched a new electric multi-component injection molding machine, which applies two-color injection molding technology in the same injection molding machine, through the two injection process, two different colors or different materials of plastics are fused together to form a complete product, the opening and closing of the mold is driven by electric power, with higher precision and faster response. QianTian Intelligence equips the injection molding machine with a magnetic mold changing system based on the need for fast mold changing, which realizes fast mold opening and closing through the cooperation of electromagnetism and permanent magnetism.
Through the preliminary communication, the difficulties faced by the customer in the process of mold change using the two-color injection molding machine mainly include the following aspects:
? Frequency and time of mold change: two-color injection molding machine is usually used for multi-species, small batch production. The current mode of mold change is 30min for a single change. Customers want the mold change process to be fast and efficient in order to reduce the time of production interruption;
? Uniformity of mold dimensions: In the process of mold change, the non-uniformity of mold dimensions increases the labor intensity of workers. Therefore, standardization and modular design of molds are crucial to improve mold change efficiency;
? Safety issues: The traditional mold change method of bolt locking molds used in the field is not only time-consuming and labor-intensive, but also poses safety risks;
In the end, QianTian's magnetic mold changing technology team provided 250T magnetic plates for on-site mold changing experiments after program research and analysis.
QianTian magnetic mold changing MMC system adopts round magnetic poles, which is easy to realize standardization and modularization, and the adjacent square magnetic poles are N/S poles, which are direct independent magnetic poles, and the two poles always keep the balance of working polarity, and the magnetic force is concentrated and non-scattering, and at the same time, the substrate is neutral and does not participate in the external magnetic transmission, so the magnetic scattering phenomenon (i.e., the magnetic leakage phenomenon) does not occur, so there is no any effect on the machine and the normal work of the mold, the machine templates, tie rods, top bars, and the mold. Machine templates, tie rods, top rods, thermocouples, and mold cores will not be magnetized.
? Switching of 5 molds with completely different sizes, weights and products on the press is accomplished by the magnetic mold changing system;
? The single die change time was reduced from 30min to 10min, improving the efficiency of on-site die change by 60% and realizing production automation;
? The original mold switching arrangement of two machine watchers was reduced to one, and the mold change operation can be completed by only one person in 10 minutes;
In addition, QianTian magnetic mold changing system has three other major advantages:
? Achieve fully automatic mold locking or unloading: QianTian magnetic mold changing system compared to the traditional platen, only need to installers through remote operation of the handheld terminal, you can achieve mold locking or unloading. The whole process is completed in a few seconds, saving more than 90% of mold loading and unloading time on average compared with the traditional clamping method;
? Structural optimization, targeted to solve equipment problems: QianTian Magnetic Die Changer System improves the number of magnetic poles and structural strength by 20% by optimizing the structure of the system, based on the fit with the customer's equipment;
? Improvement of stability: QianTian Magnetic Die Changer System has an all-steel surface, which is oil- and water-resistant. Since the equipment is a two-color machine, rotary action will occur during the working process, the alignment and structure of QianTian magnetic mold changing system supports special settings, which meets the customer's customization needs in all aspects;
The cooperation between QianTian Intelligence and KraussMaffei Technology Center on this magnetic mold change project will not only enhance the technical level and market competitiveness of both parties, but also bring new development direction and opportunities for the injection molding machine industry. Looking forward to the future, QianTian and KraussMaffei will jointly open a new chapter in injection molding machine technology, providing customers around the world with more high-quality and efficient products and services.
