6. Reasonable adjustment to reduce the total processing cycle.

7. Run the newly transferred conditions for at least 30 minutes to stabilize, and then at least continuously produce a dozen full-mode samples. It is especially valuable for multi-cavity molds to indicate the date and quantity on the ware and place them separately according to the cavities in order to test the stability of the actual operation and to derive reasonable control tolerances.

8. Measure as the sample cools to room temperature and record the critical sample measurement data for its important dimensions.

9. Compare the dimensions of each model sample and note that:

(1) Is the size stable?

(2) Whether some sizes have an increasing or decreasing trend, and the machine processing conditions are also changed, such as poor temperature control or oil pressure control.

(3) Whether the change in size is within the tolerance range.

If the finished product size does not change, the processing conditions are also normal. It is necessary to observe the finished product of each cavity, whether the quality is within the acceptable range, and the size can be changed or not changed within the tolerance. Make a note of the continuous or large or smaller than the average number of cavities to check if the size of the mold is correct.
