Company Profile

Hangzhou Spanner Science and Technology Co. Ltd. (abbr. SPN) was established in April 2008 which specializes in manufacturing, producing and selling permanent magnet Ferrite magnet and NdFeB magnet, which serves for the motor industry. The company is located in Lin′An Qingshan Science and Technology City, Hangzhou, which covers over 120 Mu, with 120 employees and the registered capital of the company is 589, 260, 52.00 RMB. SPN was appraised " High and New technology enterprise in Zhejiang Province" in 2016 and has passed ISO9001 & ISO14001 certification in 2017.

The product range of company covers high level anisotrop ferrite multi-poles magnets, ferrite segments, ferrite blocks and hot pressed NdFeB magnets, Sintered NdFeB radiation ring magnets as well as magnetic assembly. The R&D and management teams of SPN consist of experts with over 30 years′ experience in Ferrite and NdFeB, who have devoted to building a large high-grade multipole ring magnet base.

SPN adopts high performance materials to make excellent and high quality magnet like FB6, FB9, Y30, Y35. Now, there are over 100 specifications. In particular, the surface magnet strength of ferrite anisotropic can reach 2000GS. (The diameter is from OD10mm to OD74mm with 2poles to 48poles. ) The products match the international level in line with the excellent properties and consistency. SPN also provides various specifications of dry pressure and wet pressure ferrite segments, horn magnets, NdFeB low weight loss products as well as low temperature coefficient NdFeB products, etc.

The products of SPN are famous for the accurate size, stable performance and good quality by using unique technique to provide magnet solutions for customers. The products are widely used in brushless DC motor, air conditioning fan motor, precision servo motor, EPS motor, new energy automobile motor and other new generation permanent magnet motors.

SPN insists on an attitude of "pursuing excellence and perfect for serving customers". It has successfully served for many large corporations such as Mitsumi Electric Co. Ltd, Welling, Sanhua Co., Ltd, Huayi compressor Co., Ltd, Johnson Electric, etc. The products are exported to the United States, Italy, Poland, Japan, India, Pakistan and other countries.
