We would like to introduce our "3D CAD and Analysis Software." By providing conditions such as the number of hinge suspensions and door loads, we conduct strength analysis. This addresses challenges such as exceeding the machining limits of conventional molds when dimensions are excessively long. It helps prevent unnecessary capital investment and is suitable even when there is insufficient installation space in the design. 【Features】 ■ Strength analysis combining 3D CAD and analysis software ■ Analysis possible based on conditions such as the number of hinge suspensions and door loads ■ Achieves strength assurance and downsizing by using appropriate materials *For more details, please feel free to contact us.

The "fuel filler cap hinge" is a product used for the fuel filler cap of custom parts vehicles. Due to the strong opening force of standard hinges, there are issues with contact with the vehicle body, so we received a request to see if we could manufacture a heavier hinge. However, it was specified that a resin-based material could not be used for the fuel filler. To tighten the hinge's inner diameter, we minimized the clearance with the core rod and added an additional process after hinge assembly to apply vertical pressure to the pipe, eliminating the gap between the pipes and increasing the operating weight as a solution to the problem. 【Features】 ■ Hinge inner diameter managed and manufactured to 0.01mm precision ■ Clearance with the core rod minimized ■ A decisive pressing process applied to curl forming to reduce play *For more details, please feel free to contact us.

"Long Hinges (made of iron or stainless steel)" are hinges that can be manufactured in thicknesses ranging from 0.8mm to 4mm. Since the hinge part extends in a straight line, it supports the load along a line rather than at a point. This makes it easier to suppress warping and twisting of the entire door compared to using just a few short hinges. They can be made up to 3 meters in length, and surface treatment is also available. Please feel free to contact us when you need assistance. 【Features】 - Supports the entire door evenly, reducing the burden per screw and making it less likely to wobble. - Easier to suppress warping and twisting, even for thin or tall doors. - Allows for smoother opening and closing, making it easier to reduce rattling and unusual noises. *For more details, please feel free to contact us.

The "Seismic Hinge for Heavy Doors" is a product that can be used as a substitute for existing hinges as a seismic countermeasure for standard steel doors. When an earthquake causes a building to shake, deformation can occur in the door frame, making it difficult to open and close the door. However, by incorporating a spring unit into the internal structure, it can prevent difficulties in escape. It is suitable for steel doors weighing 75 kg or less, allowing for seismic measures without the need to replace the door, and we also accept custom processing for site-specific needs. 【Features】 ■ The seismic hinge is a product developed by our company ■ Suitable for steel doors weighing 75 kg or less ■ Has a track record of use over the past 20 years ■ Seismic measures can be implemented without the need to replace the door ■ Custom processing for site-specific needs is possible *For more details, please feel free to contact us.
