Past Works

PTFE Lathing

Lathing PTFE material is available, aside from CNC machining and 3d printing. 

Material: PTFE

Please feel free to contact us.

Adequate support will be provided by our experienced designers until prototype completion.

Finishing Options

Coloring/Painting

We offer a wide range of colors and finishes including solid color, metallic, clear, and gradient color.

Our in-house toning ensures that we can match the color sample you provide, and we always secure approval for the toned test pieces before proceeding.

Precision Masking

Need specific areas of your part to remain untouched during the finishing process?

Our precision masking has got you covered. Utilizing a high-precision cutting machine, we meticulously mask off areas that require protection during painting or other finish applications.

Metallizing

We use advanced aluminum vapor deposition techniques to create a metal-like finish on your parts, enhancing both their visual appeal and durability.

Composite decorations, including painting and masking on aluminum evaporation, are also available.

Pros and Cons of CNC Milling

Advantages

  • High Precision and Accuracy: CNC turning is highly precise, able to create intricate details and maintain tight tolerances consistently across multiple parts.
  • Versatility: It can work with a broad range of materials, including various types of plastic and metal.
  • Scalability: It’s suitable for both low-volume prototyping and high-volume production.

Disadvantages

  • Limited Geometry: CNC turning is primarily used for creating parts that are rotationally symmetrical. It’s not as versatile as some other processes for complex, asymmetrical designs.
  • Material Waste: Compared to additive manufacturing methods like 3D printing, CNC turning can create more waste because material is removed rather than added.

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.
