World-class technology and achievements for catheters and semiconductor testing equipment.
Currently, the demand for small springs is rapidly increasing. There are various applications, including contact springs, connector springs, and coil springs used in medical catheters, among others. Among these, the springs used in semiconductor testing equipment are particularly in demand in the microscopic world. They serve the purpose of checking whether current is flowing through the electronic circuits of semiconductors. These are ultra-fine springs with an outer diameter of less than Ф100μm, and there are only a limited number of companies in Japan that can produce them.

Company information
Microspring Co., Ltd. flexibly responds to customer requests and produces fine springs with high precision. Currently, we are stably supplying fine springs in various fields such as electronic components, mobile phones, automotive parts, and medical devices. One of our representative springs is a precision spring with an outer diameter of about 1 millimeter that supports the metal ball at the tip of a ballpoint pen from the inside. At Microspring, we continuously produce precision springs using our self-developed NC machines. This unique NC machine was developed through repeated efforts to create a numerical control method that does not rely on molds or the skilled hands of craftsmen. We have accumulated know-how in "spring making" that cannot be imitated elsewhere. We have installed our self-developed NC machines, which do not require craftsmen, in each group factory to produce and supply stably close to our customers. We ensure meticulous discussions from the prototype stage and promise rapid responses up to mass production.
