What should be paid attention when making big fracture fan with mammoth material ?

The mammoth fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan is for high value, mainly because of its high material value and time-consuming and laborious work! pls pay attention as below !

Master Gan Xianhua in Jiuhua fan Studio, who has made many mammoth fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans. The following points are summarized for reference only
Precautions before production:
1. The two mammoth bone with a thickness of 5mm-7mm are generally made of materials cut into slices.
2. Place it in a ventilated and dry place and see the changes. It will generally bend slowly to one side. The longer of time , the greater degree of bending will be. When the bending is obvious,you should mark the inside and outside of the big bone
3. When making the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan, align the internal and external marks, make a large bone surface on the outside, and bend inward. In this way, stick a half beam to prevent the bending degree from increasing inward after ventilation in the future and damaging the stick beam.
4. After the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan is preliminarily finished, the big bone can be polished with wet water, so that the polished luster is smooth and the brightness very full.
Precautions for maintenance of mammoth fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan;
1. When not in use, wrap the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan with plastic wrap and place it in a dry fan box. This can avoid wind and humidity
2. If the bending degree increases after seeing the wind, the clamping force of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan will increase. Of course, it is not easy to open it if it is too tight, so it is best to keep it moderate without deformation.
However, it is much better than bending on both sides like flowering, or bending inward while bending outward.
