3. Procedure Summaries
There are 6 types of dry pressing ferrite powder for customers: YXC-C1, YXC-C2T, YXC-C3T, YXC-C1, YXC-C2. The procedure summaries for making magnet are as follows:
- The necessary secondary additives have been added into the powder during the grinding process. Customers only need to add proper quantity of binders and lubricants. The powder must pass through 120 mesh sieve before pressing, so as binders to be uniformly distributed for better orientaton
- Please take care of the cleaning of the equipments. Any other materials and impurity should mot be mixed into the powder
- During pressing, the pressure required is ≥5000N/cm2, and the magnetic field density is >7000 Oe(560KA/m)
- The sintering temperature for reference is between 1220 °C and 1270 °C. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill
