【Echo Tech】 New way of using “Welding bar ZH54”?
Today, our boss find new technique of using Welding bar ZH54.
He had request from wedding dress design company for cutting test on cloth that uses in wedding dress.
There were 6 types of cloth which has different pattern, thread type, thickness, and softness that we had sample from the customer.
The customer were using normal scissors to cut the cloth, but because it frays, the appearance becomes bad.
He looked for a tool that doesn’t make cloth fray, and asked us for cutting test. At the work, we also have requested to not burn cloth.
(Ultrasonic cutter cut materials with high frequency vibration, and the friction heat burns thread)
We tried cut with 1. Standard blade(HA04), 2. Round tip blade(ZH09), 3. Thin blade(ZH14), which affects less to cloth.

３． 
We confirmed that cloth doesn’t get burn, cutting with those blades, but it couldn’t prevent fraying. We concluded that cloth’s softness disturbs blade, applying power to one place.
It able to cut without making fray by stretching cloth, but it needs heavy, big size, and metal made weight. We kept find other way, and finally our boss has found answer.
That is, “Welding bar ZH54”.
Line on cloth with welding bar to make flat cloth surface and easier to apply power in one place. Because the cloth surface becomes hardened, it could prevent cloth fraying.
We were only recommended to use welding bar for plastic welding, not for cloth.
The one of fact why it succeeded to weld cloth were pertaining to cloth “thickness”.
The more cloth is thinner, welding bar become more easily to weld cloth.
Please try once, if you have cloth working material.
Such a new discovery has always found in new challenge.
