Realistic-looking texture 

Ultra-Lightweight / Realistic Finishing

INAC produces ultra-lightweight motor coil mockups for electric vehicles, combining multiple manufacturing processes to achieve realistic finishing with exceptional portability. This mockup demonstrates our capabilities in creating exhibition models that accurately represent complex automotive components.

Multi-Process Manufacturing
The motor coil mockup is manufactured using a combination of TSR829 transparent stereolithography 3D printing and polycarbonate machining. This hybrid approach allows us to create complex geometries while maintaining structural integrity. Components are produced individually and assembled to form the complete motor assembly.

Professional Finishing and Painting
After manufacturing the components, INAC applies professional painting techniques to achieve realistic-looking texture that mimics the appearance of actual motor components. The decoration process transforms the transparent and machined parts into finished mockups with authentic visual characteristics. Painting is applied to both coil and stator components before final assembly.

Mockup Advantages
The lightweight mockup offers several practical advantages for exhibition and presentation purposes. No rust will appear, eliminating concerns about corrosion during storage and display. The mockup is easy to carry, weighing approximately one-sixth of an actual motor, making transportation and handling significantly more convenient. Various design approaches can be applied to meet specific exhibition requirements.

Materials and Components
Materials used include TSR829, a moisture-resistant highly transparent stereolithography material, combined with polycarbonate machining and painting. The assembly includes individual components such as coils, stator, and housing elements that are manufactured separately and painted before final assembly.

Applications
This type of mockup is ideal for trade show exhibitions, customer presentations, training models, and design verification where the weight and handling of actual metal components would be impractical. The realistic appearance provides effective visual communication while the lightweight construction enables easy setup and transport.

Please feel free to contact us to discuss your motor mockup and exhibition model requirements.
Our experienced designers provide support from concept through mockup completion, working with your specifications to create exhibition models that meet your presentation needs.

STEP5: Quality Assurance and Precision Inspection

A quality inspection is performed. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Processing and Finishing

Finishing is done by removing the supports, polishing, and applying transparency treatment. It is also possible to paint and apply plating to the formed product.

STEP3: UV-Laser Print Formation (SLA Process)

Output: The product is formed by irradiating the liquid with a laser beam of UV light and laminating it. The conditions of the external environment, such as room temperature and humidity, must be maintained.

STEP2: Model Program Generation and Support Adjustment

A program for model formation is created. Depending on the shape, it may be necessary to adjust the degree of tilt and the position of the supports.

STEP1: CAD File Submission

Upload your CAD to our online quoting platform.

STEP 3: Rendering and Scene Integration

We can also handle exterior modeling and interior structure design based on illustrations. After creating the 3D models, we can create a rendering to fit a scene. We can deliver images even if we do not proceed with production.

STEP 2: Detailed Design and 3D Modeling

Once the design is determined, drawings and 3D models will be created. The structure will be examined, taking into consideration not only the external design but also functionalities such as mating and sliding.

STEP 1: Initial Design Consultation

The first step is a meeting to discuss the project. Drawings are not required for this meeting. We will create a design from a sketch based on the overall image and concept that you have in mind.

STEP5: Quality Assurance and Inspection

We perform quality inspections. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Casting Finishing

Vacuum casting materials are cured and then taken out of the silicone rubber mold. Then we perform finishing such as deburring and gating, and they are made into finish products.

STEP3:Material Injuction

Liquid casting material is injected into the silicone rubber mold in a vacuum environment.　

STEP2: Mold Preparation

The silicone mold is cut open into a male and female mold, and the master model is removed.

STEP1: Mold Creation

The master model is fixed to a wooden frame and silicone is poured to create a mold.
