In the past years, we have accumulated much expereience in developing differents kinds of  ring neodymium magnets as per customers' requirement. Our currenct manufacturing facility can make:

Size range of ring magnets: Diameter from Ø1 to Ø200mm, Inner diameter from Ø1 to Ø100mm, Height from 0.4mm to 52mm

                                                  Tolerance can be +/-0.1mm, +/-0.05mm,+/-0.03mm

Common sizes of ring neodymium magnets: OD6-ID4x1.5, OD8-ID3x4,  OD10-ID4x1.5, OD10-ID6x1.5,  OD10-ID7x1.5,  OD10-ID8x5,  OD10-ID4x5,  OD12-ID7x2,  OD12-ID9x4,  OD12-ID9x6,  OD15-ID9x5,  OD15-ID12x2,  OD15-ID5x8,  OD20-ID4x2,  OD20-ID10x2,  OD20-ID12x6,  OD19-ID9x6,  OD27-ID16x10,  OD25-OD15x12.5,   OD30-ID6x5,  OD30-ID10x15,  OD40-ID10x10,  OD40-ID20x5,  OD45-ID15x10,  OD60-ID40x20,   OD60-ID30x15,  OD50-ID25x12.5,   OD50-ID15x12.5,  OD100-ID50x12.5,  OD100-ID50x40,  OD200-ID50x48, etc

We are still exploring in making bigger and thinner neodymium ring magnets.


Quality control

Quality is life of company

We view quality is most most important to our company as well as to our customers. So we are very careful of quality control. Our first duty is to deliver qualified block magnets to customers's hand.   We have implemented ISO 90001 since 1999 and got the certification in 2002. We have strictly raw material management, process management, quality control manamgement. 

ISO9001 certificationISO9001 certification

100% no quality cheating

This is our principle of business. It is also our serious promise to all of our customers and potential customers.It is not only for maintaining long term business relationship but also for keep our business principle which we view it as basic business deed. We will not do things like that using cheaping quality material and selling in the name of high quality magnets in order to get high margin. 

Our attitude at quality issues

In the past 10-odd years, attributing to our heavily focusing on quality, we rarely received quality complaints. Like sizes, plating, it will be not a problem any more with our current manufacturing facility and skills. But we are still very carful due to some accidentical quality issues happening like shortage of quantity,some small cracks, some cartons' damage in shipment.

1st case, for shortage of quantity, when clients receive the goods , open the cartons and find the shortage

Our attitude: Yes, it is definetely our fault. We are very sorry. We will make new production to make up for the shortage. Or we return money in relate to the shortage.

(why there is quantity shortage? Actually, it almost cannot happen now. Before packing, the magnets will be magnetized. And magnets will be packed together in very regular shape which is easy for quantity calculation. For each inner box, we will calculate quantity and put labels. Then we total the quantities. So we have been many years for no shortage in quantity.) 

2nd case, for some small cracks, when client receive the goods, open the cartons and find the cracks.

Our attitude:usually small cracks will not reduce magnetic strength, it can go on to work. So  we will negotiate with clients to keep using them. But if they cannot work, we will make new production to make up for the cracks.

(why there is small cracks? Usually, cracks is from plating, packing,magnetizing, shipment. But cracks from plating, packing, magnetizing will be taken out during our final apperance checking. So even there are some cracks, the quantity will be very small. But cracks from shipment is out of our control. Due to vibration in shipment, the magnets have the chance to impact each other and make cracks. The quantity will be also very small because we use soft packing material. For big magnets, due to plating process, magnetizing process, some small cracks are unavoidable. We will view these small cracks as qualified and normal ones. But definetely, we will take out those abnormal cracks to ensure clients can use.).

Buy from us, you do not have worry about quality any more. 

Price & Payment

Best prices and Competitive prices always

Our life-long goal is to supply ecconomic solutions to our customers. So we will think about the cost reduction before cusotmers' worry about cost. Usually, we will check the purpose or application fields of the wanted magnets. Then we will advise suitable magnets. For examples, some customers need magnets for simple industrial purpose, then we will recommend them to use lower grade magnets. Some customers need magnets for commodity products, then we will choose cheap quality magnets. But all these advised magnets should meet the requirement of purpose and application. If customers have high requirement on magnets such as magnets for motors, generators, we will strongly advise to use necessary high grade magnets. Furthermore, we will strictly control our production cost and reduce our margins as possible as can. 

In one words, You will always get best prices from us and competitive prices than from others. Buy ring magnets from us! You will get high ratio of performance to prices!

Delivery for small ring magnets, usually 7-12days.

Delivery for big ring magnets, usually 12-22days. 

In most cases, we can deliver ring neodymium magnets on time. But we have to acknowledge there is some accidental things happened which influence our delivery time like government power shortage and limit,raw material supply shortage, busy seasons,processing failure, etc.  For these accidental things, we will keep customers updated often.

In case any accidental things, we advise customers to start purchase 1 month earlier. 

Shipment ways

We are familar with international transportation. We can deliver ring magnets by air, by sea, by courier.

Packing ways

In the past 10 years, we have much experience in how to packing in order to let goods to arrive at customers' hand safely. 

We mainly use double corrugated grey board cartons inside with foams to anti-vibration. 

Our common packing size: 35*27*15cm/ctn, 0.015m3, average gross weight is 15kg/ctn. 

magnets packing carton

For air shipment , we will add some iron sheets to screen the magnetic force before boarding. 

We can even make pallet and wooden cases to pack these magnets as per customers requirement.
