Application Scenarios
Product packaging
Packing
When the ceramic insulator bead is finished, the person will be responsible for the packing.
Moulding
The moulding methods are manual, automatic and dry pressing. Ceramics are made by these three methods.
Sintering
Our company has two kilns, which have advantages in similar enterprises. We can burn more ceramic insulator bead in a short time.
