Using a binder in the material! It is possible to create magnets with high freedom of shape and complex geometries.
At Napack Co., Ltd., we handle "bonded magnets." These products are magnets formed by mixing magnetic powder and resin. Since a binder is used in the materials, it allows for high freedom of shape and the ability to create complex-shaped magnets. Additionally, insert molding with metals and plastics is also possible. Furthermore, because the raw materials are in powder form, the material yield is excellent. 【Product Lineup】 ■ SmCo bonded magnets ■ NdFeB bonded magnets ■ SmFeN bonded magnets ■ NdFeB anisotropic compression bonded magnets *For more details, please refer to the PDF document or feel free to contact us.

We operate the company under the corporate philosophy of "Integrity" as our guiding principle and "Good Friends, Good Ideas, Good Work" as our management philosophy. Regardless of the type of work, people are our priority. By expanding the circle of good friends not only within the company but also to our customers, partner companies, neighboring residents, and local government officials, we can broaden the scope and depth of our work. We aim to continue our efforts to expand this circle of good friends, both now and in the future. We also want to engage in work that allows everyone involved to share joy. We are entering an era of increasing change. There may be times when we are tossed about by great waves. We want to overcome these challenges while focusing on "the development, manufacturing, and sales of functional materials and components based on metal powders," paving the way into new fields. We aspire to pursue the mysteries of powders and perfect the creation of products that have never existed before, ones that will impress our customers.
