Product Details

Injection molding bonded magnets must be produced on respective molds, the mold is made of wear-resistant and pressure-resistant tool steel with the very smooth polished mold cavity. The very complex shape of the magnets can be created by the injection molding mold, and the other corresponding components can be molded together with the magnet that made into components. This molding process makes component production in a simple way. At the same time, the process can also meet the product's strict dimensional tolerances requests.

DIRECTION OF MAGNETIZATION

Could be according to customer's requirement to make radially, axially, diameter oriented magnetized etc.
and even for magnetic filed wave, we also could control in the type of sine wave, square wave and dual hump wave etc. 
We have prefect craft guarantee in controlling lower value on magnetic field poles range and keeping 
consistency in magnetic filed.
