6. MAINTENANCE
TE Connectivity recommends that a
maintenance/inspection program be performed
periodically to ensure dependable and uniform
terminations. Frequency of inspection is dependent
upon operator skill and care of dies, amount of use,
presence of abnormal amounts of dust and dirt, type
and size of products being crimped, and your
company’s established standards.

possible damage to die closure surfaces are shown in
Figure 6.
6.3. Die Closure Inspection
Every die set is inspected for proper die closure
before shipment. However, inspection of die closure
for excessive wear is required on a periodic basis
depending upon usage and conditions.
The die closure inspection is accomplished using
GO/NO--GO plug gages. A suggested plug gage
design and the GO/NO--GO dimensions for plug gage
members are provided in Figure 7. TE does not
manufacture or market these gages. The following
procedure is recommended for inspecting the die
closure.
1. Clean oil or dirt from die closure surfaces and
from plug gage members.

6.1. Die Maintenance and Certification
All dies are thoroughly inspected prior to shipment.
Because of the possibility of damage in transit, new
dies should be inspected in accordance with the
information provided in this section and be inspected
at regularly scheduled intervals to ensure their
conformance to standards.
Dies are coated with a preservative to prevent rust
and corrosion. Wipe preservative from dies,
particularly from crimping areas, prior to use. Do not
allow deposits of dirt, grease, or other contaminants
to accumulate on the die closure surfaces. These
deposits may cause excessive wear in the die closure
surfaces, thereby affecting the quality of the crimp.
Wipe dies frequently with a clean dry cloth and store
them in a clean, dry area when not in use.
6.2. Visual Inspection
Visually inspect die closure surfaces for broken,
pitted, or chipped areas. Although dies may gage
within permissible limits, worn or damaged die closure
surfaces can affect crimp quality. Examples of
