Mold parting-line sensor

K control must be exercised from anywhere, apart from screw penetration, then most molders will go for line pressure control as this is easier, simpler and the system is less prone to damage it is also virtually maintenance free. The use of mold parting, which occurs on injection, is now a commercial option. This is a very easy system to fit as, no machining is required as the sensor location is on the outside of the mold. However, it is probable that with the development of suitable nozzle pressure transducers that, control will be exercised in future from this part of the machine. 

The aerospace industry has recognized the major benefits associated with fiber-rein-forced composite materials [1]. The more popular techniques available for composite production are the traditional wet layup or autoclave and resin transfer molding. Efforts to further reduce processing time and improve part quality have focused on improved process control. To date, this has been based on off-line techniques. The need for online cure monitoring is widely recognized, and this will require the development of suitable in-mold sensors. The Engineering Composites Research Centre has investigated and concentrated on the specific problems encountered in the aerospace industry.
