High-efficiency production of high-precision metal parts in all fields [Cost reduction through press forming!]
The technology of shaping metal by applying pressure at room temperature is called cold forging. In the machine, wire is cut, and pressure is applied to the metal using molds, deforming it by drawing or expanding it, and automatically processing it into the desired shape. Since there is no cutting process, there are no chips produced, and material loss is minimal. Because it is processed with molds, the processing accuracy is high, and there is little variation in quality. Kagoshima Metal utilizes cold forging techniques and, through multi-stage formers, produces high-precision products in various shapes, including hollow items, items with through holes, and drawn products. The main products manufactured are metal parts for various fields, including automobiles, hydraulic equipment, and industrial machinery, as well as special fastening components, special bolts, and nuts. With a wealth of production equipment, including large machines with a pressing capacity of 400 tons, we achieve high-efficiency production by using the optimal machine suited to the shape and size of the manufactured products. 【Product Fields by Industry】 Automobiles and Motorcycles Low Voltage Equipment Building Materials Steel Furniture Tools Hydraulic Equipment 【Applicable Materials】 Carbon Steel Alloy Steel Boron Steel Stainless Steel Aluminum Copper

We will introduce the phenomenon of fluid leaking from between the flanges due to internal pressure in the container.
This article introduces the troubles that occur at the bolt connections around heat exchangers and piping, specifically focusing on the causes and improvement measures for leaks at flanges. The causes include "insufficient management of axial force (surface pressure)," "displacement and damage of gaskets," and "reduction of axial force due to temperature cycles (essential factors)." There is a minimum surface pressure required to prevent leaks, but due to the above causes, it is not possible to secure and maintain the necessary surface pressure, leading to leaks between the flanges. As an improvement measure, there is the "tensioning method," which allows for management of bending stress and axial force. It can be tightened without rotation, thus avoiding the effects of friction, allowing for axial force management, and preventing displacement by pulling straight. 【Proposed Products】 ■ Superbolt ■ Boltight *For more details, please refer to the PDF materials or feel free to contact us.

Differences in tolerance ranges lead to the existence of grades! An explanation of the differences between old and new screw grades.
Screws have grades due to differences in tolerance ranges. However, the old standards are still strongly present in the field, which can lead to troubles during product acceptance. Additionally, if you do not check your company's inspection standards and management gauges and update them with the latest information, there is a possibility that consistency in screw quality may not be maintained. In this column, we will explain the differences between the old and new screw grades and the background of their mixing. *For detailed content of the column, please refer to the related links.

By reviewing the tolerance settings in the drawings, we can improve production efficiency while maintaining quality!
When manufacturing parts with special-shaped threaded components, how much time do you typically take from drafting to starting production? Is it not the case that after drafting the drawings, you check them, confirm with the factory whether they can be produced, and sometimes receive a notification from the factory that production is not possible, leading to revisions of the drawings, and before you know it, nearly two weeks have passed? In this column, we will focus on the tolerance settings for the length of the threaded part during the drafting of drawings for special-shaped threaded components. *For more details on the column, you can view it through the related links.

Simultaneously solve both "rotational looseness" caused by reverse rotation and "non-rotational looseness" that does not involve rotation!
The "Nortlock X Series" is a product that addresses both "rotational loosening" and "non-rotational loosening" with a single solution. By combining the spring effect (which compensates for the reduction in axial force due to non-rotational loosening) and the wedge locking function (which prevents rotational loosening), it eliminates the need to only address the higher-risk issues or to complicate the work process by combining multiple products. It is used in various bolt fastening applications across the global railway industry, including bogies, couplers, brake systems, outfitting, track maintenance, and sleepers. 【Features】 ■ A single product that addresses both rotational and non-rotational loosening ■ Multi-wedge lock mechanism ■ Numerous certifications, primarily in Europe ■ Size (steel): M6 to M20 *For more details, please refer to the PDF document or feel free to contact us.
