TOTAL QUALITY MANAGEMENT
In order to meet customers' satisfaction and benefit all company members and the society, LG puts total quality management into practice strictly according to ISO/TS16949:2009 system, which obtains LG as Ningbo Export Products Quality Guarantee Enterprise.
PROFESSIONAL AND EFFICIENT MACHINING ABLITY
Ningbo LG has two machining subsidiary factories. They have inside diameter slicers, wire-cutting machines, flat grinding machines and centerless grinders, etc. The two factories have the ability to machine not only normal blocks, disks and segments, but also especially high precision small blocks and hyper-normal products, through using laser drilling and grinding to machine the SmCo products of thin-wall, deep hole, which has high precision as well as tiny hole.
EXCELLENT GEOGRAPHICAL LOCATION
Ningbo LG is located in Ningbo, an important trading port, which is close to Shanghai and well-known as China's magnetic material production base for long time. This advantage guarantees us to provide customers with kinds of difficult-machining products. With the convenient transportation, LG could ensure you a short delivery time, even your urgent products needs.
Ningbo LG supplies customers home and abroad with kinds of shapes and grades of SmCo magnets with superior quality, competitive price, short lead time and considerate service. We sincerely welcome your visit, contact and negotiation. Ningbo LG Manufacturing Co., Ltd. will be your best partner for business.
INTRODUCTION TO TECHNICAL CONSULTANT
Dr. Hartmut Nagel, who has been technical consultant since the establishment of Ningbo LG. He engaged in the SmCo research work in a global professional material and technology group—ThyssenKrupp—in Germany. Now he establishes a company, which provides NdFeB and SmCo manufacturers with equipments like hydrogen-decrepitating furnaces, pressing machines, etc, as well as technical solutions and innovative services.

NdFeB Magnets Physical Properties:
1. Neodymium Magnets are the strongest magnets in the world., whose temperature resistance can reach 200 centigrade.
2. Neodymium Magnets are easy to machine, compared to Alnico and SmCo magnets.
Not so easy to be scrapped
3. Neodymium Magnets are with high resistance to demagnetization, which makes its property quite
Stable
