Injection pressure monitoring method and apparatus |
摘要 |
A method of monitoring data concerning injection pressure in an injection molding machine is disclosed in which a multipoint sampling technique is used to acquire and store injection pressure reference data in the form of a time varying data curve for a first injection molding cycle. The reference data is used to form upper allowance data which is stored in the form of a time varying data curve having a constant offset from the reference data curve. The upper allowance data is then compared with injection pressure data acquired using a multipoint sampling technique during a second injection molding cycle and an alarm is issued if the data acquired in the second injection molding cycle exceeds the upper allowance data.
