hot runner system development direction
Anole supply hot runner design and hot runner technology for hot runner mould,hot runner injection mould.This file will show the hot runner system development direction.
At present, the hot runner system has some defects, such as complexed mould structure,damaged heater component,high cost of manufacturing,the temperature of the precision control devices, molding resin must clean without sundry, resin change and change color is more difficult, maintenance is more complex and so on, but these defects are gradually be overcome. At present, domestic and foreign mould of hot runner system development direction can be divided into the following several aspects.
The miniaturization of components, in order to realize the small products a model more cavity and large products with many hot runner filling mold. Through shrink the nozzle space, can allocate with more mold cavities,improve of the product yield and injection machine utilization.Hot runner standardization and serialization of components. At present, the user requirements of mold design and manufacturing cycle is more and more short, hot runner components will not only help reduce the standardization of design work and reduce the cost of repetition mold, but also very easy to vulnerable parts of the replacement and maintenance.
Hot runner mould design reliability is improved. Now major domestic and international company pay more attention on the hot runner manifold design and hot runner nozzle connection of pressure distribution, temperature distribution, seal of much emphasis on development.Lapped moulds can effectively increase the number of cavity, and for injection machine and mold force requirements by simply adding 10% ~ 15%. Fold type mould of hot runner in some developed countries have already used for foreign industrialization.
Improve hot runner components materials aims to increase the nozzle and hot runner abrasion resistance and used for sensitive material molding. Such as the use of molybdenum titanium alloy materials manufacturing nozzle toughness, with metal powder injection molding the sintering hot runner components has become possible.
Develop accurate temperature control system. In the hot runner mould molding, develop more sophisticated temperature control system device,It's the effcient measurement to control the manifold temperature and the temperature of molten resin to prevent overheating and product performance degradation resin reduced effective measures.
Through the pipe and hot runner nozzle components of the effective combination of design can make the total molding and the combination with hot runner technologies, thus forming 3 layer, 5 layer is even more layers of composite plastic products.
