The cold crimping technology is widely used in
the fields of wire harness manufacturing, aerospace, new energy vehicles, rail transportation, connector manufacturing, because of its characteristics of high
reliability, simple operation, cost saving and
no pollution. This makes manual crimping tools more widely used in related manufacturing industries. Then, do you know how to better use crimping tools to extend tool life? Here I will take M22520 series hand crimping pliers
for example to tell you a few about the use and maintenance of crimping pliers.
Tip 1 Crimping pliers are
precision tools which can not be transferred to other uses and can not operate
the tool indiscriminately. Please crimp with the appropriate force.

Tip 2 The right crimping tool should be chose to crimp the terminals and wires. When
the size of the terminal does not match that of the crimping pliers, there may
be insufficient crimp or excessive crimp. Do not insert rigid steel contacts or solid cylindrical contacts into the
crimp hole, otherwise it may cause damage to the crimping pliers.

Step1 Put the terminal into the crimp hole.
Step2 Insert the wire into the terminal.
Step3 Press the crimping pliers
handle properly to complete crimping.

Tip 3 Use with suitable positioners. Install and remove the crimper positioners with the correct method. When you install or remove the positioner, the tool must be in fully open position. After crimping, remove the positioner carefully and store it securely.

Tip 4 Do not twist the wire to be crimped.
Otherwise it will affect the terminal and wire crimping effect, affecting the
tension value.

Tip 5 Keep the indenter tips clean
and carefully remove any remaining deposits, but do not immerse the tool
directly in
cleaning solution.

Tip 6 Crimping pliers should be
cleaned and stored in a clean, dry place to prevent dust and impurities from
entering the crimp
frame, or it will affect the performance of pliers.

Be sure to store it carefully
and keep it safe.
Tip 7 Crimping pliers must be regularly inspected and maintained. After being used for a certain period of time, it is necessary to check the
accuracy of the crimping pliers with a Go-NOGO gauge. As shown in the picture, operate
the tool to the fully closed position. If
the “GO” gage end can pass freely, but the NO-GO
end can not pass completely, it means the tool is still qualified.

Choose the right one to detect.
Tip 8 If the crimping pliers are broken, parts are scattered or any
abnormality is found, stop using them. Do not transform the crimping tool. Do not attempt to disassemble tool or make
repairs. Please contact the factory's technical service personnel for repair.
All these use and maintenance knowledge of crimping tools, have you
gotten it?
