Experience exceptional clarity in your prototypes with our unique high transparency treatment, making INAC US the go-to choice for your clear plastic resin machining needs.

Machining Methods

CNC Milling

Resin / metal machining​ : improve a cutting process for a wide variety of materials

CNC Milling is a type of machining method that uses 3-axis and 5-axis machines to remove unnecessary parts to achieve the desired shape. It processes by carving out resin blocks.

CNC Turning/Lathing

CNC Turning is a machining method that rotates the workpiece and applies a fixed cutting tool to shave it. It is mainly suitable for machining cylindrical parts. With a composite lathe, it is possible to machine complex shapes in one machine by combining lathe and milling operations.

Available Clear Plastic Options

Material Description
PC(Polycarbonate) Polycarbonate is an excellent choice for prototyping impact-resistant and transparent parts due to its strength and optical properties. It can be machined, 3D printed, or injection molded, making it suitable for a variety of applications, such as safety equipment, lenses, and lighting components. Our unique transparent processing technology allows us to produce beautiful clear polycarbonate products without requiring extensive polishing work.
Acrylic Acrylic is often used for prototyping transparent parts and models due to its optical clarity and weather resistance. It can be machined, laser cut, or thermoformed, offering versatility in creating intricate designs, especially for light-guiding components, displays, and enclosures.
PMMA PMMA (Polymethyl Methacrylate) is often used for prototyping transparent parts and models, similar to acrylic. Its optical clarity, UV resistance, and weatherability make it ideal for creating prototypes that require a high degree of transparency, such as light-guiding components, displays, and enclosures.
PVC PVC (Polyvinyl Chloride) is commonly used for prototyping pipes, fittings, and other fluid handling components due to its chemical resistance and durability. Its transparency is inferior to that of acrylic or polycarbonate.

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.
