Based on the previously established industry standards for hot runner response speed, the required equipment, and the step-by-step operation procedures, the following core considerations should be taken into account:
Environmental Condition Control: Testing must be conducted in a constant temperature workshop at 20-25℃. Avoid direct exposure to cold air on the hot runner to prevent ambient temperature fluctuations from interfering with the heating time data.
Equipment Accuracy Verification: A standard platinum resistance thermometer must be calibrated before testing to ensure the equipment's accuracy meets standards and avoid inaccurate response speed determination due to measurement errors.
Ensuring Consistency of Operating Conditions: During testing, the hot runner must be in an empty mold state without molten material, consistent with actual production conditions. This prevents molten material from absorbing heat and slowing down the heating rate, resulting in distorted results.
Safe Operating Procedures: High-temperature protection must be implemented throughout the testing process. After the hot runner has heated up, direct contact with metal parts is prohibited to prevent burns.
These precautions ensure accurate and reliable test results, fully complying with industrial-grade testing specifications.
