Problem
Fiber snaps when
mold top lowered.
Material flows
excessively outside
of mold cavity or
does not flow down
mold cavity
("puddling").
Rev. A, August 14, 2024
Possible Cause
Recoat mold not properly
aligned to fiber.
Grooves on recoat mold plate
and cap do not line up.
Recoat mold plates are dirty.
Fiber is not taught in FHBs.
Grooves on recoat mold plate
and cap do not line up.
Solution
Check that the fiber is seated in the FHB V-grooves
correctly. Check that the Tension Fiber Process is in
the splice sequence and that it has been allowed to
execute.
Ensure that the FHBs and Transfer Jigs used are not
those from another machine.
Align mold to single piece of stripped fiber stretched
between FHBs in transfer jig.
Contact Thorlabs for splicer servicing.
By far the most common cause of recoat problems.
Dirt between quartz mold plates will not allow them
to lay flush, causing the acrylate to flow excessively
outside the mold cavity. The recoat mold plates
should be cleaned as described in Section 7.2.
Set up Post Splice Tension or ensure that the Post
Splice Tension process executes before removing the
Transfer Jig from the Splice Station.
Contact Thorlabs for servicing.
