Why Choose Plastic CNC Machining for Your Projects?

Plastic CNC machining uses computer-controlled tools to cut plastic materials into precise shapes. This makes parts that are very accurate and can be made quickly. Whether you need one test part or thousands of parts, our cnc machining service is perfect for you.

Materials We Work With

We can machine many types of plastic to fit your needs:

Material	Special Features	Best Uses
ABS	Strong, easy to machine	Electronic cases, toys
PEEK	Heat-resistant up to 340°F	Medical tools, airplane parts
Ultem®	Flame-retardant	Safety equipment
Nylon	Tough and flexible	Gears, bushings
Polycarbonate	Clear and impact-resistant	Windows, shields
PTFE (Teflon)	Very slippery, chemical-resistant	Food equipment, seals
HDPE	Food-safe, water-resistant	Containers, cutting boards
Acrylic (PMMA)	Clear like glass	Light guides, displays
Delrin®	Low friction, strong	Gears, bearings

Our team at Istar Machining can help you pick the best plastic for your project. Need medical-grade materials? We have FDA-compliant options too!

Selecting the Right Plastic for the Job

Different applications demand different material properties. Here’s a quick guide:

For High-Temperature Environments

If your part operates in heat, PEEK or PTFE are excellent choices, capable of handling continuous temperatures up to 260°C (500°F).

For Transparent Components

Need visibility? Polycarbonate (PC) offers exceptional impact strength and clarity, while Acrylic (PMMA) provides excellent optical clarity and aesthetics.

For Low-Friction or Sliding Applications

For parts that need to move smoothly against others, Delrin (POM) and UHMW-PE offer excellent lubricity and wear resistance.

For Food-Safe Applications

When parts come into contact with food, specific grades of UHMW-PE or Delrin (POM) are suitable, meeting regulatory requirements.

For Outdoor Applications

For components exposed to the elements, PVC offers good weather and chemical resistance, while Polycarbonate (PC) provides UV resistance and toughness.

Applications of CNC Machined Plastic Parts Across Industries

Aerospace Industry

Aerospace components demand lightweight yet high-strength materials. PEEK is often used for its excellent mechanical properties and low density.

Medical Devices

Medical tools and equipment require biocompatibility, sterilizability, and precision. PEEK and Delrin (POM) are common choices.

Automotive Sector

Car parts need durability and resistance to heat and fluids. Nylon 6/6 and Delrin (POM) are frequently used for mechanical and fuel system components.

Electronics

Components for electronics often require dimensional accuracy and electrical insulation. PTFE and Acrylic (PMMA) are used for insulators, housings, and light guides.

Industrial Machinery

Factory equipment requires robust parts that withstand continuous operation. UHMW-PE and Nylon 6/6 provide excellent wear resistance for rollers, guides, and bearings.

How Precise Are Our Plastic CNC Machining Services?

At Istar Machining, we make parts with amazing precision:

Standard Tolerance: ±0.001″ (thinner than a human hair!)
Ultra-Precision: ±0.0002″ for critical parts
Maximum Part Size: 24″ x 48″ x 12″
Surface Finish: Mirror-polish or textured as needed

This means your parts will fit perfectly and work just as you designed them. Our 5 axis machining can create complex shapes that other companies can’t make.

Tips for Designing Optimal Plastic Parts for CNC Machining

To ensure the best results and cost-effectiveness for your machined plastic parts, consider these design tips:

Maintain uniform wall thickness where possible to minimize warping.
Incorporate radii on internal corners rather than sharp edges.
Avoid excessively thin walls that may be fragile or difficult to machine accurately.
Consider how the part will be securely held (fixtured) during machining.
Remember that different plastics have unique machining characteristics.
Consult with us early on complex geometries to ensure manufacturability.

Sustainability in Plastic CNC Machining

We care about the environment at Istar Machining:

Recycled Materials: Options like Econyl® recycled Nylon
Chip Recycling: We recycle all our plastic waste
Eco-Friendly Options: Biodegradable PLA for appropriate applications

Frequently Asked Question

What's the difference between plastic CNC machining and 3D printing?

CNC machining cuts away material from a solid block, while 3D printing builds up material layer by layer. CNC gives stronger parts with better finish but can waste more material.

How fast can I get my plastic parts?

Standard time is 3-5 days for prototypes. Need it faster? Our rush service can deliver in as little as 72 hours!

What's your minimum order quantity?

Zero! We can make just one part or thousands. That’s the beauty of cnc plastic machining.

Can you match special colors?

Yes! We can match most Pantone colors with colored plastic or painting services.

How do I know which plastic to choose?

Our experts will help you select the best material based on strength, temperature, chemical resistance, and cost needs.
