Our Features

Our high quality springs are created through elaborate conceptions
and our thorough practice of putting the customer first.

Elaborate Conception

Technical development based on the concept that "Even a single tiny spring is an important part that forms the heart of a precision product".

Our company has manufactured precision springs as both trial manufacturing and mass production.

Our company can manufacture products on any scale from trial manufacturing to mass production. Prototypes are made with automatic machines, and this makes it possible to provide manufacturing with uniform quality even in mass production. We elaborate on springs to make them better, by referring to the drawings that we are given.

Thorough Quality Control

  • Building Quality in the Factory: From the receipt of order to production, a system of thorough controls and checks are implemeted at all stages of production until final shipping, further ensuring high quality.
  • Quality Guarantee: Products are delivered with a "Product Inspection Results Chart" assuring product quality.
  • Product Delivery Management: Computerized thorough product delivery management.
  • Quality Maintenance: All tools and metallic molds are produced in-house, allowing for high precision quality maintenance.

Types of Springs

A thousand technologies for a thousand applications.

TORSION SPRING

A torsion spring is a spring that is subject to
twisting load (torque) about the axis of a coil.

Manufacturing performance   Wire diameter : 0.03㎜〜1.8㎜

COMPRESSION SPRING

In this type of spring, also generally known as a pushdown spring, the compression load (the load on the coil axis) and the deformation are proportional.

Manufacturing performance   Wire diameter : 0.02㎜〜1.5㎜
Shape track record : long winding coils、conical、barrel、
irregular pitch, irregular outer diameter

TENSION SPRING

A tension spring can be thought of as essentially the same
as a compression spring (the coil is generally a tight coil).

Manufacturing performance   Wire diameter : 0.08㎜〜0.7㎜

WIRE FORMINGS

Moldings using various forming machines
(Formed wire springs).

Manufacturing performance   Wire diameter : 0.1㎜〜2㎜

Material

TypePiano wire, Stainless steel wire, Platinum wire, Phosphor bronze wire
ShapeRound wire, Flat wire
