Alternating Temperature Technology: Variotherm mold temperature control Alternating Temperature Technology (ATT) is a complete system for particularly efficient variotherm liquid-operated temperature control of injection and injection compression molds by means of a near-surface arrangement of heating/cooling channels. ATT combines a customized alternating temperature system with specially designed and manufactured cavity inserts and mold components. Variotherm mold temperature control involves heating the cavity wall prior to injection of the melt to a temperature that exceeds the glass...

STWS Alternating Temperature System SINGLE STWS alternating temperature system operates with two separate circuits that contain thermal fluid with a different temperature. The required temperatures of each circuit can be adjusted to suit the process. Both SWTS circuits contain the same fluid. Water is recommended for temperatures of up to 200° C, while oil is suitable for very rare applications that operate with temperatures of up to 300° C. The system is equipped with an external valve station for switching the two circuits from bypass mode to mold temperature control mode. Signals for the...

SINGLE Temperiertechnik and Sauer Product present ATT as a joint product. SINGLE is responsible for the design and supply of the alternating temperature systems while Sauer focuses on the construction, design and production of suitable mold inserts. Both partners cooperate in the development of complete solutions for customer projects. The individual products and services can also be ordered independently from either one of the partners. SINGLE has been developing, producing and selling high-performance temperature control systems for more than 40 years. The company’s product portfolio...
