At Aoi Spring Co., Ltd., we received a request from a plating contractor and manufactured a plating jig for aluminum wire. The material used is A5052-H34 with a wire diameter of φ0.3mm, and the product size is approximately 250mm x 180mm. It was processed using a wire forming machine. Our company is capable of handling wire processing products of such large shapes. In addition, we have various past production achievements, including "wire processed products for coffee cups," "fishing hardware," and "plating jigs." [Production Achievements] ■ Wire processed products for coffee cups - Wire forming processing - Type of spring: Wire processing - Material: SUS304-WPB φ3.0mm ■ Aluminum wire φ3.0 wire processed products - Type of spring: Wire processing - Material: Aluminum wire A5052-H34 φ3.0mm *For more details, please refer to our catalog or feel free to contact us.

At Aoi Spring Co., Ltd., we received a request from a client in the medical field and designed torsion springs and kick springs to compensate for insufficient rebound during door opening and closing. Since the counterpart was already completed, the hooking area was limited, resulting in a complex shape. However, we confirmed the workability during assembly, and it was adopted for mass production. 【Production Achievements】 ■ Medical Torsion Spring Kick Spring SUS304-WPB 　・Type of Spring: Torsion Spring 　・Material: SUS304-WPB Stainless Spring Steel 　・Wire Diameter: φ0.9mm 　・Processing Method: Single-shot processing with a spring forming machine *For more details, please refer to the catalog or feel free to contact us.

At Aoi Spring Co., Ltd., we manufacture long-length tension springs using our equipment in a single process. If we were to manually process one side of the hook, the costs would increase. Our company is committed to cost reduction by processing even large springs in a single operation with our equipment. Additionally, we have a variety of past production achievements, including "tension springs with a tight D/d on one side of the coil," "twisted hook tension springs," and "prototype tension springs in U-hook shape and conical coil." 【Production Achievements】 〔Type of Spring: Tension Spring〕 ■ Free length 350mm tension spring ・ Material: SWP-B φ0.3mm ■ Tension spring with a tight D/d on one side of the coil ・ Material: SWP-B φ2.6mm ■ Twisted hook ・ Material: SUS304-WPB φ1.8mm ■ Prototype tension spring in U-hook shape, conical coil ・ Material: SUS304-WPB φ0.6mm ■ Medical tension spring SUS304-WPB ・ Material: SUS304-WPB (TF) glossy material φ0.6mm *For more details, please refer to our catalog or feel free to contact us.

At Aoi Spring Co., Ltd., we manufacture compression springs based on requests from home appliance manufacturers. The wire diameter is φ0.3mm, with a small coil diameter of φ3.0mm and a large diameter of φ5.5mm. Since the seating part has a square shape, we used a wire forming machine for production. In addition, we have various past production achievements, including "conical springs SUS304-WPB φ0.2mm," "prototype compression springs for toys," and "compression springs for machine parts SWC-80c." 【Production Achievements】 〔Type of Spring: Compression Spring〕 ■ Compression Spring Wire Diameter φ0.3mm Battery Spring - Material: SWP-B φ0.3mm ■ Conical Spring SUS304-WPB φ0.2mm - Material: SUS304-WPB φ0.2mm ■ Prototype Compression Spring for Toys - Material: SUS304-WPB φ1.4mm *For more details, please refer to the catalog or feel free to contact us.

We received an order for spring processing with a wire diameter of φ20mm. The processing was done at a cooperating factory of Aoi Spring Co., Ltd., and after adjustments and inspections in-house, we delivered it 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 known 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 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 arise). It offers the advantages of rapid response to design changes and reduction of material waste, making it ideal for cost reduction. Aoi Spring's extensive wire forming machines can accommodate your needs. 【Features】 - No initial investment required - Rapid response to design changes - Reduction of material waste - Capability to handle 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 small volumes 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, and assembling (riveting and welding) them 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 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 a single double torsion spring in the installation environment, there are advantages such as reducing the number of parts and improving work efficiency. 【Features】 ○ Kick spring ○ Capable of processing the arm section into complex shapes ○ Advantages such as reducing the number of parts and improving work efficiency ○ Proposals for optimal designs based on 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.

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 conical shapes, barrel shapes, uneven pitches, and long coils (with Aoi Spring achieving a maximum length of 500m). At Aoi Spring, we offer designs tailored to our customers' applications. We also process special materials to accommodate the material requirements suited to 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 shapes, barrel shapes, uneven pitches, long coils, etc. ○ Proven wire diameters: φ0.1mm to φ22.0mm ○ Custom designs available based on application For more details, please contact us or download the catalog.
