Coating process for a spring with a wire diameter of φ40μm (about the diameter of a hair).
For compression springs that require delicate handling due to their thin wire diameter, we apply a coating that has good adhesion (*1) and is according to the specified film thickness (in sub-micrometer units) (*2). *1 To prevent the coating from peeling off due to the expansion and contraction of the compression spring. *2 To ensure that the thickness of the coating does not compromise the load value of the spring.

Company information
Our business at Ibaraki Plating Industry involves applying plating to metal parts entrusted to us by our customers, in accordance with their requests. Our plated products are utilized in various fields, including sensor components in automobiles, electronic devices such as smartphones, digital cameras, and wearable devices, as well as medical equipment. In recent years, we have focused on "gold plating" of components for semiconductor inspection jigs, as well as micro contacts (plungers) and fine precision springs, which we consider our "strength." We aim to be a company that is trusted and can contribute to our customers, employees, and the local community, and we strive to be a group of engineers specializing in the plating processing field. In particular, we will pursue plating technology for precise and fine electronic components. We kindly ask for your warm support and assistance.
