Core Record Required Fields:
Basic Information: Keep track of the calibration date, calibrator's name, Husky temperature controller serial number, matching hot runner mould number, and calibrated thermocouple serial number and graduation number, clearly identifying the calibrated object's unique identification.
Calibration Parameters: Record the original temperature deviation, cold junction compensation parameters, temperature offset compensation value, and error correction values for each temperature point in multi-point calibration. Keep all parameter change records.
Verification Data: Take measurements of standard thermocouples at three or more temperature points, compare them to the displayed values of the Husky temperature controller, and analyse the temperature fluctuation range after 30 minutes of constant temperature.
Verification Conclusion: Indicate whether the temperature measurement accuracy met the standard after calibration, whether it passed verification, and the next scheduled calibration date. The calibration professionals must sign to affirm, completing the closed loop.
Record Format and Retention Methods
Paper Version: Use a standard temperature control equipment calibration record log. Fill out the record by hand and store it in the equipment maintenance file to meet the industry quality system's traceability requirements. Electronic Version: Enter calibration data into the production line MES system or equipment maintenance electronic ledger while uploading temperature curve screenshots during the calibration process to ensure long-term data traceability and facilitate subsequent retrieval and comparison.
Additional Compliance Requirements: The record must include the calibration certificate number of the standard temperature measuring equipment used in this calibration, demonstrating that the instrument is still valid and ensuring the legality and validity of the calibration results.
All calibration records must be categorised and kept for at least three years to meet the product quality traceability and auditing requirements of high-end injection moulding industries including automotive and medical.
This record-keeping system completely meets the quality management requirements for hot runner temperature control equipment and can be used immediately to archive and monitor Husky temperature controller calibration results.
