Twisted spring, phosphor bronze wire, C5191, Φ1.4

Bronze wire develops "springiness" through heat treatment.

Material: Phosphor bronze wire, C5191W Wire diameter: Φ1.4 Springs are sometimes required to have properties such as non-magnetism, electrical conductivity, and corrosion resistance. It is often difficult to satisfy these properties with iron-based or stainless steel spring materials, so copper alloys are chosen. The most commonly used material for coil springs is "phosphor bronze wire." Phosphor bronze wire exhibits "springiness" only after heat treatment, so it must undergo heat treatment after forming. The heat treatment temperature is around 250 degrees and is referred to as low-temperature annealing. (For more information on phosphor bronze wire, please refer to the related links.)

Introduction of case studies on the manufacturing of coil springs for automotive parts!

Introduction of case studies on the manufacturing of coil springs for automotive parts!

I will introduce a case where we supported a company that was troubled by production stoppages at overseas factories by providing domestic production and alternative mass-produced products.

Our company can accommodate various metal press products such as flat springs, coil springs, disc springs, wave springs, thin plate springs, and precision presses. We also handle insert molded products, clinched press products, and heat-adhesive press products. 【Production Case Introduction】 In 2021, due to the lockdown caused by COVID-19, our customer faced difficulties as production at their overseas factory came to a halt. As our company has a wealth of experience in processing various automotive spring products, we received an urgent request from the customer for the production of automotive spring products. We produced approximately 300,000 pieces for this urgent request, while also managing other mass-produced items, and we were able to meet the customer's requirements and deliver the desired production quantity. By supplying approximately 300,000 parts this time, we were able to contribute to the Japanese automotive industry by providing alternative parts supply to Japanese automotive manufacturers without stopping their production lines. As a result, we responded quickly to the urgent short-term request and maintained high quality, earning a "Special Contribution Award" from the customer. *For more details, please download the PDF or contact us.

Spring design - Prototyping, short delivery time

Spring design - Prototyping, short delivery time

If you provide us with the general design requirements, we will design and prototype within a short timeframe.

The twisted spring in the photo was designed and prototyped by our company. We proceeded with the design based on the following specifications you provided: 1) Coil inner diameter, 2) Load at installation to maximum angle, 3) Durability (1 million cycles) The designed spring can be prototyped in a short lead time. The spring in the photo was delivered about one week after the order was placed. We can manufacture from a quantity of one. Our company accepts the manufacturing, design, and prototyping of various springs. If you provide us with rough design conditions, we will propose the optimal specifications and produce a prototype. We understand that some may be unsure about how to specify the design conditions for the spring. Our technical staff will respond carefully, so please feel free to consult with us.

Deformation and sagging of springs: Causes and countermeasures.

Deformation and sagging of springs: Causes and countermeasures.

Introducing the causes and countermeasures for deformation and wear of springs in spring troubles!

"Settle" refers to the phenomenon where the material of a spring undergoes plastic deformation during use, resulting in a change in the dimensions of the spring, primarily caused by insufficient material strength. The adequacy of the material's strength can be calculated based on the spring's usage conditions. Countermeasures for "settle" involve changing the material to one with higher durability, increasing the wire diameter, and other specification modifications. In doing so, care is taken to select specifications that do not alter the spring's force characteristics (spring constant or load), but if there are space constraints for the spring, discussions with the customer will be necessary. If there are no issues with the strength calculations, potential causes of "settle" may include: 1) improper heat treatment after spring formation, or 2) use in an environment exceeding the heat resistance temperature. Our company addresses spring-related troubles. If you send us the deformed item, we will verify its strength and durability and propose improvement measures. Our technical staff will respond carefully, so please feel free to consult us. Tsurugaoka Spring Co., Ltd.

Causes and countermeasures for spring breakage and damage.

Causes and countermeasures for spring breakage and damage.

The clues to identifying the cause of the damage are the lifespan calculations and strength calculations.

The clues for identifying the cause of breakage are lifespan calculations and strength calculations. If a spring breaks below the calculated results, the cause of the breakage is suspected to be "stress concentration" originating from scratches or machining marks. When we examine the springs upon consultation, we often find scratches or machining marks caused during processing. In this case, reworking with attention to these scratches can lead to improvement. If the timing of the breakage aligns with the calculations, the cause of the breakage is thought to be insufficient material strength. The countermeasure for breakage in this case is to change the specifications of the spring. Specifically, this may involve changing the material to one that is more durable or increasing the wire diameter, while considering the balance to avoid altering the spring's force characteristics (spring constant, load). Our company addresses spring-related issues such as breakage and sagging. If you send us broken samples, we will propose countermeasures and, if desired, we can also produce improved prototypes. First-time customers are also welcome to consult with us without hesitation. In fact, most of the customers who consult with us have never done business with us before. We look forward to your inquiries.
