• The card, amount of use, and handling of the dies.
• The degree of operator skill.
• The presence of abnormal amounts for dust and
dirt.
• Your own established standards.
All dies are thoroughly inspected before packaging.
Since there is a possibility of die damage in shipment,
new dies should be inspected in accordance with
Section 4 when received in your plant.
4.1. Cleaning
Do NOT allow deposits of dirt, grease, and foreign
matter to accumulate in the die closure surfaces and
on the bottoming surfaces of the dies. These deposits
may prevent the dies from bottoming fully and may
also cause excessive wear in the die closure surfaces,
thereby affecting the quality of the crimp. The dies
should be wiped clean frequently with a clean cloth.
4.2. Visual Inspection
Visually inspect the die closure surfaces for chipped or
pitted conditions. Although dies may gage within
permissible limits, worn or damaged die closure
surfaces are objectionable and can affect the quality of
the crimp. Examples of possible damaged die
surfaces are show in Figure 5.

†Die closure dimensions apply when dies are bottomed but not under pressure.
‡Material - Tool steel.
Figure 6
2. Assemble dies so they are bottomed but not
under pressure. See Figure 7A.
3. With dies bottomed, inspect the die closure using
the proper plug gage. Hold gage in straight
alignment with the die closure and carefully try to
insert without forcing, the GO member. See Figure
7B. the GO member must pass completely through
the die closure. Try to insert the NO-GO member.
The NO-GO member may enter partially, but must
not pass completely through the die closure.
4. If the dies meet GO / NO-GO gage conditions,
the dies are dimensionally correct.
5. If dies do not meet the GO / NO-GO gage
conditions, contact your local TE Representative.

4.3. Die Closure Inspection
Every die is inspected and tested for proper die
closure before packaging. An inspection should be
performed periodically to check the die closure for
excessive wear.
Die closure inspection is accomplished using GO /
NO-GO plug gages. TE neither manufactures nor sells
plug gages. A suggested plug gage design and the
GO / No-GO dimensions of the plug gage members
are listed in Figure 6. The following procedure is
recommended for inspecting the die closures.
1. Clean oil or dirt from the die closure surfaces,
bottoming surfaces, and plug gage members.
