Capable of preheating SMC loads up to 762 mm wide by 2 mm long in under one minute, the Macrowave SMC preheater has a PLC, interfaced to the moulding press, Improved productivity which controls the Macrowave L-200 series preheater for Sheet Moulding Compounds A new preheating system for plastic sheet heat cycle time, moulding compounds (SMC) that uses power level, and radio frequency heating technology has uniform heating throughout the entire conveyor movement to synchronize with been introduced by Radio Frequency Co., thickness of the sheet moulding compound the press operation. For optimizing Inc. of Millis, Massachusetts. This new instantly, without requiring any efficiency, the conveyor can either feed the system is reported to enhance the temperature differential to force heat from SMC charge straight through the press or distribution of reinforcement fibres in the the surface to the centre by conduction. By return it to the feed end after heating. moulding process, thus improving product facilitating the movement and distribution Macrowave™ preheaters comply with quality and strength and reducing press of fibres throughout moulded parts, thus OSHA and FCC standards. cure time by 50%. It is especially effective improving their strength and surface finish, for thicker bosses and structures. this RF preheater reduces press cure time The Macrowave SMC preheater is priced The Macrowave SMC Preheater provides which enables a 100% increase in from $95K up, depending on belt size and other customer requirements. All systems More information are available with RFC's exclusive Founded in 1946, Radio Frequency Company specializes in developing and manufacturing high MacroCare programme for preventive frequency heating systems to improve efficiency in many industrial applications.
