MAINTENANCE AND INSPECTION
Perform a maintenance and inspection program at least once a month to ensure dependable and uniform
terminations. Frequency of inspection can be adjusted to suit your requirements through experience.
Frequency of inspection depends upon:
The care, amount of use, and handling of the dies.
The type and size of the products crimped.
The degree of operator skill.
The presence of abnormal amounts of dust or dirt.
Your own established standards.
Dies can be damaged during shipment. When you receive new dies, inspect them in accordance with the
following instructions.
7.1.
Cleaning
Do not allow deposits of dirt, grease, and foreign matter to accumulate on the die closure surfaces or the
bottoming surfaces of the dies. These deposits can prevent the dies from bottoming fully and cause excessive
wear in the die closure surfaces, affecting the quality of the crimp. Wipe the dies clean frequently with a clean
cloth.
7.2.
Visual inspection
Visually inspect the die closure surfaces for broken, pitted, or chipped areas (Figure 9). Even if the dies gage
within permissible limits, worn or damaged die closure surfaces are objectionable and can affect the quality of
the crimp.
