Compact actuators

We are developing compact electric actuators as an engineering plastic gear application product. By applying high-strength resin materials and utilizing CAE to reduce stress at the roots of the teeth, we have achieved a smaller gear module. Compared to products currently on the market, it has reduced the actuator's volume by approximately 30%. By miniaturizing the actuator, installation in compact spaces is possible. We design and propose solutions to ensure that the reduction ratio and output characteristics meet the customer’s specific requirements.

EMI shield resin cases

We are developing EMI shield cases that are capable of shielding electromagnetic waves. EMI（Electro Magnetic Interference）is the phenomenon that electromagnetic waves generated by electronic devices affect the operation of nearby other electronic equipment. Modern electrified vehicles utilize various electronic devices and systems, so making EMI countermeasures are increasingly important. Since resin cases typically cannot suppress EMI, we have implemented the following measures to address this issue. We will select and propose the appropriate resins and metals to meet the customer’s specific needs.

・Metal coating

・Insert molding of metal plates

・Enhancing the shielding performance of resin materials through the inclusion of specialized fillers

Large resin cases

We are developing large resin cases with the aim of having them replace aluminum die-cast cases. The aluminum plate insert resin case is a composite case that addresses the weaknesses of standard resin cases: case strength, EMI suppression, and heat dissipation performance. The inverter components for electric vehicles are complex-shaped parts that bring out the excellent moldability of resin materials, and they incorporate various elemental technologies to facilitate heat dissipation. We have introduced an injection molding machine of 600-ton class mold clamping force for development use and are now advancing the development of large resin cases.
