ESI Group's PAM-RTM for CATIA V5 is a dedicated Workbench presented inside the CATIA V5 environment; it is a fully integrated software tool to provide trade oriented solutions for liquid composite molding processes (RTM, infusion, ect) directly within CATIA V5. PAM-RTM is a software solution for Liquid Molding processes (LCM) like the RTM process (Resin Transfer Molding). PAM-RTM can be used to design and develop new tooling and processes for composite materials.PAM-RTM was mostly designed over the last 15 years based upon specifications of european aeronautic industry. One can visualize the flow front like if you had a transparent mold. The filling time and the possible air entrapments are predicted. PAM-RTM optimizes parameters that directly impact the presure distribution during the mold filling such as injection pressure, flow rate, closure forces and the position of injection gates and vents.
