In the hot July, we visit our partener factory. The weather is so hot, but we ares enthusiastic.
We received hosptiable reception and we have meating, communicate freely and worked out solutions to our clients' problems.
Our partner take the six of us on a tour of the sample showroom.

High precision and small enameled flat copper wire
Corona resistance series
Ultra-thin Enameled flat copper wire
Conductor size: 0.020*0.15mm
Insulation thickness: 0.003mm
Self bonding layer thickness: 0.001mm
The outside layer in the abov picture is the insulation layer
-It covers the conductor uniformly and thinly
-The corners has thicker insulation although the conductor is extremly thin
-On the premise of ensuring performance, requirments of 0 pinhole quality can be met

Then we visited the litz wire workshop, these are enamelled single wires in storage.
This is the stranded wire being wound.
This is the mylar litz wire workshop, and a multi-strand wire is being produced.
The engineer answer our questions patiently.
This is the production line of silk covered litz wire.
The quality control department displays various testing equipment to ensure product quality.
Then, we visited the large production workshop of enameled copper wire.
There are smart production lines for thick enameled wire, thin wire and ultra-fine wire.
Robots replace manual labor, improving efficiency and reducing costs.
Three days is a short trip， but We know products better after this visit.
We are full of confidence and move on!
