Modeling Service

What We Do

Lightweight cross-sectional model

Manufacturing unique and innovative designs by your designers often requires drawing of built-in mechanisms and housing. 

Well–versed designers in our Design and Development Department can work directly with your designers to make proposals on prototype production as well as mass production.

Why Choose Us

Designing Capability

We will design based on sketching, drawing or concept. We convert your ideas to CAD data to utilize its virtual images and designs and to support you in mechanism designing.

Past Works

Engine Visualization

An Internal visualization model of engines and transmissions used in automobiles/industrial machinery.

The model can be used for observing oil poured inside the transmission. Using simulations, we can perform analysis that is normally difficult such as dropping in oil under its own weight and observing the generation of bubbles.

We also design electrical equipment in-house that can do things such as making a light shine when turning the engine handle, or connecting to speakers to play audio.

e-Axle Electric Sample

This is a mock-up sample of an e-Axle’s internal components with emphasis on movement and design. The loader and gears rotate at three different speeds, and the electrical components are designed to change the color of light emitted according to the rotation speed. This sample is sure to catch the attention of visitors at an exhibition.

What is an “e-AXle”?
The e-AXle is a unit for electric vehicles that combines an electric motor, power electronics, and gearbox. This reduces electric drive complexity while maintaining compactness and light weight.

Cross Sectional Model

A significant reduction in weight can be achieved by manufacturing “cut models” through resin processing and decorative treatments instead of conventional ferrous and nonferrous metals.

The reduction in weight lowers transportation costs and reduces risks in handling. 

Get In Touch!

If you have something you want to make, please contact us. Even a rough idea is OK.

We will give shape to your idea and deliver it to you. Please feel free to contact us.


Yes, our designers will create the 3D models for you.

Yes, please do contact us for electrical designs. We will support you in creating more attractive products such as display samples with LED lights.

We can create all sorts of designs even from rough sketch concepts. Please contact us for mechanical designs, concept designs, electrical designs, or any other problems you would like to solve.

Yes, we can make such accommodations. For parts with matings, modeling is performed with clearances taken into consideration. We check the matings before shipment to ensure a high quality.

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.

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 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.

STEP5: Verification

We have an assortment of manual and CNC coordinate measuring machines, roughness measuring machines, and various other measuring instruments. We are committed to quality, and there’s no better proof of that than the fact that when many of our customers buy INAC’s services and experience the quality, they come back again to place repeat orders.

STEP4: Decorating, plating, printing

Paint and plating treatments can be added to processed products. Few companies are able to handle the entire process up to and including decoration. The ability to deliver everything in a short period of time speeds up product development. Colors can even be reproduced exactly as desired, as in-house color mixing is can be done.

STEP3: Creation

We create things using a variety of manufacturing methods, including cutting, 3D printers, casting, aluminum molds, and lathing. Sometimes, additional work is performed at a machining center to improve the precision of the 3D printed products. Manufacturing possibilities are expanded by making full use of each machine through this process. Or we can meet customer needs by makinng full use of each machine through this process.

STEP2: Proposal for the method of production based on the meeting

In addition to the intended application and operating environment, the delivery time, quality requirements, and target cost are also taken into account when considering production methods. Our sales staff, who are well versed in prototyping with knowledge on which materials and what processing methods to use, will propose the most appropriate manufacturing method.

STEP1: Reception of drawings or data, and meeting on applications and use cases

We will hold a meeting with you to discuss the details. For example, if the purpose of the prototype is to observe the inside of the equipment, we’ll need to gather enough detail to determine things like if any liquids will pass through, what temperatures can be expected, whether there should be any leaks, etc. We consider this meeting to be very important for the process because determining the optimal production method will depend greatly on the intended application among other factors.
