how to detect plastic mandrel when it breaking?
my company manufactures hydraulic hoses.
it has three layer.
1st layer is tubes(inner rubber tubes)
2nd layer is wire braid (brass coated)
3rd layer is cover (rubber)
plastic mandrel is using to produce tube at 1st process.
plastic mandrel is important part to shaped the tube for first process.but plastic mandrel easy to break and it give our problem when to extract from hoses (last process).if hard to extract plastic mandrel still in the hoses.so operator need time to find breaking point with the hoses 200meter length.hose thickness 2cm.
i think ultrasonic sensor is the best solution, but i dont know it can detect or not material from plastic. so,any suggestion to use high performance sensor for solve this prblem.
