We will introduce one of our core technologies, the winding process, with accompanying illustrations.

Small winding resistors are one of the main products of Rikyu Electric. We provide an illustrated introduction to the most important process of winding fixation for winding resistors. If you are looking for alternatives due to the discontinuation of existing model numbers, or if you are interested in the winding process beyond just resistors, please take a moment to read our materials. We also undertake partial processes, not just finished product sales. If you are interested, please do not hesitate to contact us. Flow after downloading the materials: 1. In addition to the automatic reply email, we will send an email from the Ipros site. 2. If you have specific interests, please reply with details about the items you are considering for use and any current issues you are facing. *We will only proceed to the next steps if we receive contact from you. 3. We will respond to your inquiries and discuss future meetings. 4. We will visit your company for meetings (web meetings are also possible. For custom products, we would prefer to meet in person if possible).
