SINGLE ATT 'Alternating Temperature Technology' is an inpidually configured system solution for liquid-operated variotherm temperature control of injection moulds, compression moulds and other mould types. As the active system fills moulds alternately with warm and cold thermal fluids, it can actively heat or cool processes in defined alternation. Variotherm temperature control used in combination with suitable mould inserts allows variations in temperature of more than 100 °C in critical areas or in complete moulds. In order to achieve this, the SINGLE ATT system operates with two separate circuits that contain thermal fluid with a different temperature. Both ATT circuits contain the same fluid. Water is recommended for temperatures of up to 200 °C, while oil is suitable for applications that operate with temperatures of up to 350 °C. The system is equipped with one or several external valve stations for switching the two circuits from bypass mode to mould temperature control mode. Signals for the switch-over from cooling to heating are transmitted by the machine control via programmed I/Os according to process requirements. 什么是ATT？ SINGLE ATT“变温技术”是为注塑模、压铸模和其他模具类型的液体操纵变模温而单独配置的系统方法。作为热冷流体交替填充模具的动态系统，它能够准确而频繁地变换加热和冷却的过程。变温控制与适当的模具镶嵌结合，在模具的关键区域甚至整个模具，温度变化可以超过100 °C。为了达到这点，SINGLE ATT带两个独立的回路运行，这两个回路含有不同温度的热流体，但流体是同一介质。温度高达200°C时推荐用水作为介质，温度高达350°C时推荐用油作为介质。系统装备了一个或几个外部阀站，用于从旁路模式到模温控制模式的两个回路的切换。用于切换从冷却到加热的信号是机器按照工艺要求编程后的I / O（进/出）进行控制。 Areas of application 应用领域： • Injection moulding of thermoplastics 热塑性塑料的注塑成型 • Production of components made from fibre-reinforced composites 用纤维加强的复合材料生产部件 • All cyclic processes with temperature profile 所有带有温度曲线工艺的循环加工过程 Your benefits of ATT for plastics injection moulding processes: ATT用于注塑生产后，您的利益： Higher cost-efficiency 更高的成本效率 • ATT homogenizes the cooling time required over the complete mould.
