Manufacturing chart
In GMAG, we produce all magnets under strict quality control systems, whatever one piece or one million pieces. We believe perfect finished product is produced through step-by-step process control instead of being tested at the last step. Take a look at our Manufacturing Chart:
Quality control
In GMAG, we believe quality product is the first element for the company¡¯s existing and growth. From the beginning of the company¡¯s establishment, we stick to the conception of assuring every unit magnet we offer be high-quality and satisfactory for client. In past years, we got approval from ISO9001:2000. Therefore, every batch of products is manufactured under our strict control system. Each step of raw materials purchasing, production, property test, chemistry test, finish test, store and delivery is recorded and traceable, by which we assure to provide quality products to client.

a. |
Slight unconformity is permitted. Should weak magnetic force tested, the batch of products is considered as unpassed and need thoroughly tested. |
| b. |
Magnetised products are tested after coating while unmagnetised products are tested before coating, then demagnetized and tested. |
