We received a request for spring processing with a wire diameter of φ20mm. The processing was done at a cooperative factory of Aoi Spring Co., Ltd., and after adjustments and inspections in-house, it was delivered to the customer. It is said to be used for the vibration-damping function of equipment. SUP9 is Cr-Mn steel (chromium-manganese steel). It is also referred to as spring steel and is commonly used for large springs. 【Features】 ○ Type of spring: Compression spring ○ Material: SUP9 (chromium-manganese steel) ○ Wire diameter: φ20mm For more details, please contact us or download the catalog.

Wire processing allows for the bending of wire materials into any shape using a wire forming machine. Since it does not use press molds, there is no initial investment required compared to pressed products (although in special cases, costs for tools and jigs may occur). It offers the advantages of rapid response to design changes and reduction of material waste, making it ideal for cost reduction. Aoi Spring will meet your needs with its extensive range of wire forming machines. 【Features】 - No initial investment required - Rapid response to design changes - Reduction of material waste - Capable of handling high-difficulty projects and short delivery times - Processing of special materials is also available, accommodating materials suitable for the usage environment For more details, please contact us or download the catalog.

There are various shapes of leaf springs and pressed products, ranging from those with a small volume and simple shapes to those with complex shapes. The load characteristics may vary depending on the method of installation. We provide precision leaf springs using press and multi-forming machines. 【Features】 ○ Skilled in high-speed production of battery-related components using progressive dies ○ Introduction of ultrasonic cleaning machines enables in-house integrated production ○ Capable of processing both pressed products and spring products in-house, as well as assembly (crimping and welding) For more details, please contact us or download the catalog.

The torsion coil spring, also known as a "kick spring," generates torsional torque (moment) from the central axis of the coil section and is used in a direction that twists the spring wound in a cylindrical shape relative to the coil's centerline. With the latest equipment at Aoi Spring, it is possible to process the shape of the arm section (bending, hooks) into complex shapes. Additionally, by combining two right-hand and left-hand torsion springs into one double torsion spring, there are benefits such as reduced number of parts and improved work efficiency. 【Features】 ○ Kick spring ○ Capable of processing the arm section into complex shapes ○ Benefits such as reduced number of parts and improved work efficiency ○ Ability to propose optimal designs according to the installation location and method ○ Capable of handling high-difficulty projects and short delivery times For more details, please contact us or download the catalog.

Tension coil springs, commonly referred to as "tension springs," have tightly wound coils and hooks at both ends, allowing for tensile loads. The shape of the hooks is determined based on the shape of the corresponding parts. Aoi Spring Co., Ltd. offers load design and safe hook shape proposals tailored to customer applications. 【Features】 ○ Tension spring ○ Tightly wound coil section ○ Hooks at both ends allow for tensile loads ○ Hook shape is determined according to the shape of the corresponding parts ○ Proposals for load design and safe hook shapes are available based on application For more details, please contact us or download the catalog.

Compression coil springs, commonly referred to as "compression springs," have a proportional relationship between the compressive load and the deflection amount. Depending on the application, they come in various shapes such as conical, barrel-shaped, uneven pitch, and long coils (with Aoi Spring achieving a maximum length of 500m). At Aoi Spring, we offer designs tailored to our customers' specific applications. We also process special materials, allowing us to accommodate materials suited for the spring's usage environment. With the introduction of state-of-the-art equipment, we can process springs at a rate of 6,000 pieces per hour, compared to the typical 2,000 pieces. 【Features】 ○ Compression springs ○ Proportional relationship between compressive load and deflection amount ○ Available in conical, barrel-shaped, uneven pitch, and long coil forms ○ Proven wire diameters: φ0.1mm to φ22.0mm ○ Custom designs available based on application For more details, please contact us or download our catalog.
