The University of South Carolina McNAIR Center is interested in developing a custom compression molding machine for consolidation of thermoplastic composite materials. We are currently seeking to procure the induction heated platens for this system. Specifications for Induction Heated Platen System The Contractor will provide a 200kw or greater induction heated platen system (≥100kW for top plate, ≥100kW for bottom platen) for consolidation of thermoplastic composite materials. The system must be capable of supporting peak temperatures of 800 Fahrenheit (427 Celsius) and 300psi (20 bar). Heated Platens and Elements The heated area of the system is required to include top and bottom heated and cooled plates sized 30 x 40in. (760 x 1016mm) and must fit within an overall dimension box of 43 x 56 x 17in. to be compatible with designed press. The induction coils should be directly integrated into the platen tooling and system to include compatible induction generator. Heating and cooling integration should both be included within each platen to ensure uniform heating and cooling properties, efficiency, and compactness of size to fit within hydraulic press. The system must include thermocouples (TC) for process controls, a minimum of one TC for each platen and the ability to locate the thermocouple in multiple locations as desired. Ability to manage heat in top and bottom platens separately to accommodate asymmetric tooling. Heating Rate Expectations: Target heating rate is 68-77 °F/min (20-25C/min) for base platen molding surface. Supporting Equipment: The system must include the following supporting equipment: 1. Human Machine Interface controller (HMI). 2. Cooling system and thermoregulated unit(s) (less supporting infrastructure). 3. All other pertinent peripheral equipment and connections needed for setup of the system.
