ナパック List of Products and Services

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 would like to introduce the "gears and pulleys" that we handle. Rotational transmission components (gears, toothed pulleys, ratchets, etc.), which are one of the important mechanical elements, have recently required high precision due to advancements in control technology through electronics. Our company is also committed to enhancing technology development and equipment to meet this demand. 【Materials】 ■ Iron-based ■ Stainless steel-based ■ Copper *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "machine parts" that we handle. Sintered machine parts allow for complex shapes and significantly reduce machining, enabling substantial rationalization for customers, including cost reduction. We continuously research and develop various types of materials according to the applications and performance requirements of our products. 【Materials】 ■ Iron-based ■ Stainless steel-based ■ Copper *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "oil-impregnated bearings" that we handle. The function of oil-impregnated bearings is to maintain a small amount of oil, less than a drop (0.05cc), without losing or damaging it within a limited space, ensuring the designated bearing lifespan, which is a significant challenge. We continuously research and develop the "technology of harmony" regarding the shape, material, pore structure, and impregnated oil of oil-impregnated bearings.

Powder metallurgy is a manufacturing process that involves placing metal powder into a mold, compressing it to solidify, and then sintering it at high temperatures to create parts. It excels in producing complex and high-precision components in large quantities, offering excellent cost performance. Because the raw material is in powder form, the material yield is outstanding. 【What Napak Can Do】 ◆ Oil-impregnated Bearings The challenge with oil-impregnated bearings is to maintain a small amount of oil, less than a drop, within a limited space without losing or compromising it, ensuring the specified bearing lifespan. We continuously research and develop the "technology of harmony" regarding the shape, material, pore structure, and impregnated oil of oil-impregnated bearings. ◆ Mechanical Components Sintered mechanical components allow for complex shapes and significantly reduce machining, enabling substantial rationalization, including cost reduction for our customers. We continuously research and develop various types of materials according to the applications and performance requirements of the products. ◆ Gears and Pulleys Rotational transmission components, which are one of the important mechanical elements, have recently required high precision due to advancements in control technology through electronics.
