Plastic/Resin for Prototyping

CFRP lightweight resins cutting
CFRP lightweight resins prototyping

Take a look at INAC US’s plastic/resin prototyping services that cater to various types of resins.

In addition to machining, we also offer modeling and casting methods, allowing you to choose from a wide variety of materials and processing techniques.

The sample on the left was machined using a high-precision 5-axis machining center to create a CFRP (Carbon Fiber Reinforced Plastic) machined product.

Available Resin/Plastic Options

MaterialDescription
ABSABS is a popular choice for prototyping due to its excellent balance of strength, toughness, and ease of processing. It can be easily machined, 3D printed, or injection molded, making it suitable for a wide range of prototypes, from consumer products to automotive components.
POMPOM (Polyoxymethylene) is a preferred choice for prototyping precision parts and mechanical components due to its excellent stiffness, low friction, and wear resistance. It can be easily machined or injection molded, making it suitable for creating prototypes of gears, bearings, and moving parts in various industries.
PPPolypropylene is a versatile thermoplastic polymer that is highly appreciated for its excellent chemical resistance, elasticity, and fatigue resistance. This makes it a prime choice for creating prototypes that require durability in bending and flexing, such as living hinges, containers, and automotive parts. PP can be processed through various methods, including machining, injection molding, and 3D printing, allowing for flexibility in prototyping applications across industries.
NylonNylon is a family of synthetic polymers, known for its high strength, temperature resistance, and abrasion resistance. These properties make nylon an ideal material for functional prototypes that must withstand wear and tear, such as tool parts, functional gears, and high-stress components. It can be processed by machining and is particularly well-suited for 3D printing, providing prototypes with a fine balance of strength and durability.
PEEKPEEK is a high-performance engineering thermoplastic with exceptional mechanical, thermal, and chemical resistant properties. It is often used for advanced prototypes that require robustness in harsh environments, such as aerospace, medical, and automotive applications. PEEK can be machined and 3D printed to produce prototypes that must maintain structural integrity under high temperatures or in chemically aggressive environments.

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.
