東洋ゼンマイ List of Products and Services

Our company supplies "spring products" that are active in a wide range of fields from consumer to industrial as a specialized manufacturer of springs. What we are introducing this time is the "bamboo shoot spring." It is a spring made by winding rectangular cross-section plates into a conical shape. It is capable of obtaining a large load and absorbing energy relative to the volume of space it occupies. We can handle everything from design to prototyping and mass production. Please feel free to consult us even for a single piece! 【Common Materials】 Hardened steel strip (SK85M, SK95M) Stainless steel strip (SUS301) 【Main Applications】 Ball screw covers

Our company supplies "spring products" that are active in a wide range of fields from consumer to industrial applications as a specialized manufacturer of springs. 【Examples of Products (Partial)】 ■ Contact-type spring… A standard spring suitable for applications with high rotation speeds. ■ Non-contact type spring… Has low energy friction loss, and torque changes linearly. ■ Constant output spring… Output load and output torque are almost constant. Additionally, we offer products such as "hardened steel strips," "stainless steel strips for springs," and "spring assemblies," all of which showcase our technology! *For more details, please refer to our catalog. Feel free to contact us as well.

The heat-treated steel strip is a steel strip that has undergone "slitting," "edge processing," "deoxidizing heat treatment," "tempering," and "coloring" on polished special steel. It is a material that combines high hardness, high elasticity, wear resistance, and high flatness. Since rust can occur, rust prevention measures such as applying oil are necessary. The strip width can be manufactured from an extremely fine 0.8mm. The hardness can be adjusted within the range of 480 to 590 HV. We also accept orders for small lots. For more details, please contact us or refer to the catalog.

Non-contact spiral springs are spiral springs in which adjacent coils do not touch each other. There is no energy loss due to friction, and the torque changes linearly. Due to the fewer number of turns, they are used in applications with low rotational speeds. We offer comprehensive support from design and prototyping to mass production. We also conduct torque tests and fatigue tests. Additionally, we provide assembly services. For more details, please contact us or refer to our catalog.

The contact-type spring is a widely used spring in general. It is used housed in a case. When housed in the case, the adjacent coils are in contact with each other, resulting in energy friction losses; however, the torque remains stable. Due to the high number of turns, it is used in applications with high rotational speeds. We can provide comprehensive support from design and prototyping to mass production. We also offer torque testing and fatigue testing. Additionally, we can assemble cases and other components. For more details, please contact us or refer to our catalog.

Founded in the 5th year of the Showa era ≪Pride and technical expertise as a long-established Japanese spring manufacturer≫ - We accommodate "small-lot production of various types." - We support "prototype design of springs and spring mechanisms." Please feel the potential of springs. ● Energy-efficient springs ● Springs for new applications ● Springs used in various places ● Environmentally friendly springs Currently, they are used in toys, cord reels for home appliances, timers, as well as in diverse fields such as roll screens for homes and buildings, seat belts in cars, reclining seats, and drink holders. Although we do not directly see them, springs are actively involved in various aspects of our daily lives. Moreover, not only springs but also fields utilizing heat treatment technology for special steel strips are highly regarded. Toyo Spring aims to further specialize in two business areas: spring manufacturing and heat treatment technology. ◇◇ For more details, please request materials or download the catalog ◇◇
