We have released the 2023 magnet calendar!

Understand the basics of magnets! We are giving away a comprehensive catalog of permanent magnets featuring characteristics and product examples, along with the latest inventory list.

This is the "Permanent Magnet Products Comprehensive Catalog" from Niroku Seisakusho, which processes and sells permanent magnets and related products. It includes numerous listings of the characteristics and examples of each type of magnet. 【Featured Products (Partial)】 ◆ Ferrite Magnets These offer the best cost performance. They are brittle but resistant to rust. ◆ Neodymium Magnets These have the highest magnetic energy among existing magnets. They are prone to rust, so they are treated with nickel plating for rust prevention. ◆ Samarium Cobalt Magnets These have high magnetic energy, second only to neodymium magnets. They are brittle but can be used in high-temperature environments. ◆ Other related products/magnetic application devices, etc. For products in stock, orders placed by 5 PM can be shipped the same day with free shipping across Japan for as little as one magnet. Please consult us for custom magnets, including short lead times for basic shapes and production of special shapes. 【Stock List of Featured Products】 We have a wide range of ferrite magnets, neodymium magnets, samarium cobalt magnets, alnico magnets, rubber magnets, cap magnets, and related products listed by various shapes and sizes. For more details, please check with us.

We accept custom orders for magnets. For neodymium magnets (round and square), we may be able to shorten the delivery time to about two weeks.

We will introduce a case study of custom-made neodymium magnets in a round shape with a short delivery time. ■Normal delivery time is approximately 8 weeks In the case of this product, it typically involves procuring or manufacturing the raw material, followed by processing it to the desired size. After that, surface treatment (plating), magnetization, pre-shipment inspection, and packaging are carried out. The overall normal delivery time is approximately 8 weeks. ■Short delivery time is approximately 2 weeks In the case of a short delivery time, existing raw materials are processed to the desired size. After that, surface treatment (plating) is omitted, and magnetization, pre-shipment inspection, and packaging are performed. The overall delivery time is approximately 2 weeks. Although the cost will increase compared to the usual manufacturing method, we can process existing magnets and raw materials consistently domestically, reducing the delivery time to less than half. 【Manufacturing case】 Material: Neodymium magnet N-35 Size: Φ7.2×2 Quantity: 10 pieces For more details, please contact our company.

Challenges Before Implementation A company that manufactures and sells confections using juice was naturally thawing fruit juice stored in drums. The thawing process (natural thawing) took 3 to 4 days in summer and over 10 days in winter, occupying a large space within the factory during that time. Additionally, it required personnel to manage the process, which significantly constrained productivity. There were also concerns about the deterioration of the freshness and color of the juice, leading to a demand for a more efficient and high-quality thawing method. Effects of Implementation The implementation was based on confirming the effectiveness through actual machine tests conducted in the Shinagawa test room beforehand. It was confirmed that the thawing of drums with the Proton thawing machine could be completed in one day year-round. Therefore, a customized proposal for the introduction of a large differential pressure rapid thawing machine and storage facility was made, maintaining high quality without compromising the freshness and flavor of 100% juice. Additionally, the need for a dedicated thawing space was eliminated, allowing personnel to be reassigned to other departments, which significantly improved productivity. The thawing machine received high praise for achieving both quality preservation and efficiency simultaneously. *We are preparing a test machine and look forward to your visit.

The "Proton Defroster" is a system that can defrost delicate fish roe, such as mass salmon roe and red salmon roe, which are sensitive to temperature changes, in a high-quality and hygienic manner. In conventional methods, high temperatures and long operation times were unavoidable, leading to uneven defrosting. Additionally, tanks placed outdoors were difficult to clean and had hygiene issues, such as mold growth. The "Proton Defroster" uses a steam boiler as its heat source, allowing for uniform defrosting in a low-temperature, high-humidity environment with 100% humidity. It eliminates uneven defrosting and prevents color fading and flavor deterioration. With efficient heat transfer through the latent heat of steam condensation, the color of the fish roe remains vibrant, and the flesh stays firm during defrosting. As a result, in the cleaning and trimming processes (deveining), the roe is less likely to be crushed, enhancing the effectiveness of enzyme treatment, improving yield, and increasing work efficiency. The Proton Defroster, which preserves color, shape, and texture without compromising freshness and quality, greatly contributes to quality control and product value enhancement in the seafood processing industry. *We have a test machine ready and look forward to your visit.
