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: 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.
