ABSTRACT:
A method for checking or controlling cross linking in products made of elastomeric material has a mold of a fixed volume provided with at least one pressure sensor detecting pressure variations in the mold during cross linking in order to obatin data referring to the progress of the cross linking in the case of laboratory applications, while in manufacturing, it can provide an automatic control of the duration of the various states of the manufacturing cycle by means of microprocessor controlled equipment to which such sensors are connected. The peak pressure reached in the mold is measured and a decrease in its gradient as time passes is detected. Subsequently an increase in the gradient is detected and the time required to obtain a variation of a pre-established order is determined. This data is used to obtain information on how cross linking is progressing and for automatically controlling the manufacturing equipment.
