Customized Countersunk Magnets , Ndfeb Round Magnets With Hole In Center

customized round magnets with hole in center , OEM countersunk ndfeb magnets

The Temperature Coefficient of Br is given on the product data sheets (see NdFeB - sintered). This is the average rate at which losses are expected.

This published data is based on conservative estimates. The data implies that the loss rate is a linear function, however, tests show that this loss is nonlinear.

The loss function is difficult to characterize, therefore formula to predict this behavior has not been developed. The temperature coefficient,

however, has been shown to have a correlation to the material's intrinsic coercivity value at RT.

T = Temperature above RT

RT = Room Temperature (20℃)

Highlights:

1. Counter sunk holes tolerance control:

(1). During the process of grinding and cuting, controlled by high precise machines.

(2). after plated, we will check the magnet tolerance as per drawings based on AQL standard.

2. Non-magnetism protective package:

(step 1). sorting the defect product after magnetized

(step 2). check the total quantity as per client order, and packed one by one with good spacer.

(step 3). Vaccum packing based on magnet size and inner box

(step 4). Inner box packing and put the shipping label on the inner box

(step 5). Foam protection packing, and then iron packaging to finish the Non-magnetism protection

(step 6). Exporting carton with table tie and then pallet, post magnet Grade, size, quantities or special requirements

3. Customer feedback:

we will have the Customer Satisfaction Questionnaire from most of our customers.
