PC(Polycarbonate) Prototyping Methods

CNC Machining

CNC Machining provides precise, repeatable results when working with polycarbonate (PC) materials. 

Thanks to its strength and dimensional stability, PC is well-suited for milling, drilling, and other subtractive processes. 

CNC Machining can achieve tight tolerances and fine surface finishes, making it ideal for complex parts that need reliable structural integrity and detailed features.

Lathe Processing

Lathe Processing is an excellent option for producing rotational or cylindrical PC parts. 

By spinning the material and removing excess via cutting tools, it’s possible to craft smooth, consistent shapes with high precision.

 Polycarbonate’s impact resistance and machinability allow lathe operations to shape components like shafts, housings, or cylindrical enclosures without compromising overall part durability.

FAQ about INAC US's PC(Polycarbonate) Prototyping Service

A. Lead times vary based on part complexity and finishing requirements, but most PC prototypes can be delivered within 5–10 business days. Expedited services may be available for urgent projects.

A. Yes, we offer various surface treatments, including vapor polishing, anti-scratch coatings, and painting. These treatments help enhance clarity, durability, and overall aesthetics.

A. Absolutely. Polycarbonate is known for its exceptional impact strength, so prototypes are typically suitable for mechanical stress testing and real-world operational evaluations.

A. We can provide sanding, polishing, vapor polishing, painting, and assembly services. We can also add inserts, seals, or other components to finalize the prototype.

A. Yes. Polycarbonate inherently possesses high transparency. Although it becomes cloudy after machining, it can be easily restored to its original clarity through a solvent-based polishing process. This makes it ideal for producing experimental models for visualizing internal flow paths or display pieces that showcase internal structures.

Guide to PC(Polycarbonate) Prototyping

What Is PC(Polycarbonate) Material?

Polycarbonate (PC) is a strong, transparent thermoplastic known for its exceptional impact resistance, high optical clarity, and good heat resistance. 

It finds wide applications in industries such as electronics, automotive, aerospace, and consumer goods. 

Grades of PC(Polycarbonate) Material

Grade Value
General-Purpose Polycarbonate (PC) General-purpose polycarbonate provides outstanding impact strength, high clarity, and moderate heat resistance. It’s often used in safety guards, housings, and transparent panels, striking a balance between cost, toughness, and optical quality.
Reinforced Polycarbonate (Glass-Fiber or Carbon-Fiber Filled) Reinforced (glass or carbon-filled) PC offers increased stiffness, strength, and dimensional stability. Used in structural or load-bearing components, it can replace metal in applications like automotive brackets and industrial machinery parts.
Optical-Grade Polycarbonate Optical-grade PC boasts superior clarity with minimal distortion, making it ideal for lenses, protective visors, and transparent security enclosures. It retains PC’s impact resistance while ensuring excellent light transmission.

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.
