We would like to introduce our "Engineering" services. In concept design and vehicle design, we can assist you with high-level skills from sketches to design mock-ups and parts design. Additionally, prototyping is our core business, and without a doubt, we prioritize delivery time and precision. Our motto is to deliver satisfactory products through methods tailored to your objectives. 【Design Lineup】 ■ Concept Design ■ Engineering Design ■ CAE Simulation ■ Tool Design ■ FEM Simulation *For more details, please refer to the related links or feel free to contact us.

"Why is a car prototype company making drones?" At Topia's Kanagawa office, we manufacture various carbon products daily to achieve weight reduction in vehicles and more. Our range extends to four-wheeled vehicles, two-wheeled vehicles, welfare, sports, aviation, and space. Weight reduction in drones is a crucial factor directly related to "payload" and "flight time." We have gathered our existing technologies to take on the challenge of drone development. 【Japan Drone 2025 Exhibition】 Date: June 4 (Wednesday) - June 6 (Friday), 2025, 10:00 AM - 5:00 PM Venue: Makuhari Messe Booth: AL-18 *We will be showcasing the drone itself at the exhibition mentioned above. We look forward to your visit. For more details, please download the catalog or feel free to contact us.*

We handle changes in destination for prototype vehicles and operational vehicles, modifications and replacements of old and new ENG units, motors, and batteries for regulatory compliance and advanced development, as well as measures for regulatory compliance, changes in destination, and durability testing. Please feel free to contact us when you need our services. 【Business Activities (Partial)】 ■ New vehicle assembly ■ Modification for change of destination ■ Modifications for regulatory compliance ■ Modifications for advanced development unit replacement ■ Alignment inspection, measurement, and adjustment *For more details, please download the PDF or feel free to contact us.

In the sports equipment industry, there is a constant demand for lightweight and high-strength products. In particular, durability that can withstand intense exercise and lightweight properties that enhance performance are crucial factors that influence product competitiveness. Traditional welding methods have faced challenges such as shape changes and strength reductions due to thermal distortion. The synchronous stirring welding (SSW) that our company has introduced enables high-speed welding with low heat input, addressing these issues. 【Application Scenarios】 - Bicycles requiring high-strength and lightweight frames - Skis that balance durability and design - Impact-resistant protectors 【Effects of Implementation】 - Performance improvement through product lightweighting - Enhanced durability due to high joint strength - Suppression of shape changes caused by thermal distortion - Increased design flexibility
