JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Monitoring, open and closed-loop control of RTM and SMC processes.
The large-scale repeatable production of lightweight structures is a key technology for the future mobility. The production of lightweight components and composite structural parts is a challenge for process monitoring and quality assurance. Kistler’s new special sensor for Resin Transfer Molding (RTM) is the key to optimizing the processing of crosslinking molding compounds for polymer lightweight applications in automotive and aeronautical engineering.The sensor Type 6161AA… measures cavity pressure levels of up to 200 bar and is therefore ideal for industrial applications, particularly for monitoring, open- and closed-loop control of RTM processes, high pressure RTM (HP-RTM) and SMC (Sheet Molding Compound) processes involving pressure levels of up to 150 bar.Typical application examples are the recognition of filling errors or the control of cascade filling processes via several gates. Other applications for the new sensors include processing of low-viscosity polymers such as liquid silicone (LSR) and elastomers. In addition to pressure measuring, the sensor is also suitable for measuring the vacuum in the evacuated cavity. This way, this sensor records the condition of the relevant process.About the Kistler Group:The Swiss-based Group is a leading global supplier of dynamic measurement technology for pressure, force, torque and acceleration. Kistler’s technology is used to analyze physical processes, control industrial processes and optimize product quality.Kistler has a full range of sensors, electronics and systems for engine development, vehicle technology, assem-bly technology, plastic and metal processing as well as for biomechanics.More information: www.kistler.com
