Occasionally customer want to use the magnet on their projects for the first time, they usually do not know what kinds of magnets is suitable,
absolutely our engineers can help offer you a best solution as per your applications, however you should consider below guidelines:
Highlights:
1. Counter sunk holes tolerance control:
(1). in the process of grinding and cuting, controlled by high precise machines.
(2). after plating, 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
(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.
