RESIN CUTTING

This portfolio showcases cross-sectional “cut models” produced by INAC using precision resin cutting and decorative processing. By using resin instead of traditional metal, these cut models are lighter and easier to handle, reducing weight and transportation costs while enabling cost-effective prototyping.

Internal Visualization Through Resin Cutting
Resin cutting reveals hidden internal structures and allows visualization of mechanisms, fluid flows, and component interactions that cannot be observed in assembled products. By making the internal mechanisms visible, engineers can perform fluid analysis, confirm mechanical operation, and validate design decisions during the development stage.

Precision Form Representation
Our precision resin cutting capabilities, including polycarbonate and acrylic cutting technologies, enable sharp geometric definition and accurate dimensional representation. This precision is particularly valuable for design verification, as detailed edges and fine features can be reproduced without requiring extensive post-processing, making resin cut models ideal for design review and concept validation.

Material Flexibility and Cost Advantages
By replacing metal with resin, INAC delivers cut models with significant weight reduction and lower manufacturing costs compared to traditional metal tooling. Resin materials offer excellent optical clarity when needed and can be combined with decorative finishing techniques — including painting and plating — for enhanced visual presentation.

Applications

  • Internal mechanism visualization for automotive and industrial machinery
  • Fluid flow analysis and hydraulic system verification
  • Design review samples for product development
  • Exhibition and presentation models
  • Educational and training models
  • Component functional verification

Diverse Manufacturing Capabilities
INAC uses 3-axis and 5-axis CNC machining centers to process a broad range of resin materials with precision. Our accumulated expertise allows us to deliver complex geometries and detailed surface features that meet demanding quality standards while maintaining cost efficiency.

Please feel free to contact us to discuss your cut model and internal visualization requirements.
Even a rough idea is a great starting point. Our experienced designers provide support from concept through completion.

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.
