When to Prefer CNC Plastic Machining over 3D Printing
- Precision and Accuracy: When it comes to precision, CNC plastic machining is the way to go. The high-speed cutting tools used in CNC machining allow for exact results with tight tolerances that can be difficult to achieve through 3D printing.
- Identical Parts: CNC machining is the ideal choice for high-volume production runs. 3D printing, on the other hand, is better suited to low-volume production and prototyping.
- Large or Complex Shape: 3D printing has come a long way in recent years, but CNC machining still offers more flexibility and control when creating complex shapes and structures. CNC machining also allows for the cutting and shaping materials that 3D printing cannot handle, such as metals or composites.
Post Machining Services for CNC Machined Plastic Components
Post-machining processes offer additional benefits to CNC-machined plastic components, such as improved surface finish, strength, and durability. At Rally Precision, we provide a range of post-machining services, some of which are below.

Engraving
Engrave your CNC machined plastic components with text, logos, or artwork for a professional finish and improved aesthetic. It is a cost-effective way to enhance the look and feel of your plastic parts.

Etching
Etching is a great way to add texture and depth to your parts while also improving their durability and grip. Our etching process uses chemical or mechanical methods to create patterns on the surface of your parts.

Polishing
Do you want to give your parts a glossy finish? Our polishing services can help you achieve just that. We use advanced machinery to achieve a smooth, glossy finish on your parts that will last for years to come.

Coating
Rally offer custom coating solutions for your CNC plastic machined parts. This will help protect them from wear, abrasion, and corrosion. You can also choose a color or texture to give them a more attractive look.
A Complete FAQ Guide
Still have some questions about CNC plastic machining? Here are some of the most commonly asked questions. In case of any other queries, feel free to contact us and our team will be happy to assist you.
1. What is CNC plastic machining?
CNC plastic machining is a subtractive process of cutting, shaping, and forming plastics using computer numerical control (CNC) machines. It is most commonly used for producing prototypes and small to large-batch runs.
CNC machines, such as 3-axis or 5-axis, offer precise control over the machining process, resulting in parts with high levels of accuracy and repeatability.
Rally Precision is one of China's leading CNC plastic machining service providers, offering high-quality parts with fast turnaround times at competitive prices.
2. What are the advantages of CNC machining plastic?
CNC machining plastic is incredibly versatile and cost-effective for creating complex parts. It offers many advantages over traditional fabrication processes, including:
- The high degree of accuracy and repeatability.
- Ability to produce complex shapes with tight tolerances at a low cost.
- Ability to create parts that are more resistant to wear and tear.
- Greater flexibility in design compared to traditional methods such as injection molding.
- Fast turnaround times and low setup costs.
- Potential for automation, reducing labor costs, and increasing production speeds.
- Reduced need for post-processing and finishing. Holes, threads, and other features can be machined directly onto the part.
3. How much does plastic CNC machining cost?
CNC machining plastic costs depend on complex design, material type, quantity, and quality requirements. Generally speaking, you can expect to pay anywhere from $10 to $100 per part for simple plastic parts and up to several hundred dollars for more complex designs.
At Rally Precision, we also offer discounts for bulk orders, so if you need a large quantity of the same parts, you could be eligible for a reduced rate.

5. Are plastic parts durable?
There is no one-size-fits-all answer regarding the durability of plastic parts. It largely depends on your material and the machining process employed.
For Example - Polycarbonate (PC) machined parts are much more durable than Polypropylene (PP).
So, choose your material wisely or consult us to find the best material for your application.
6. What is the machining process for plastic?
The machining process for plastic differs from the machining process for metals. Because plastic materials are generally softer than metal, the cutting tools needn’t be as strong or durable and can be replaced more often.
Furthermore, plastic machining requires different cutting speeds and feeds than metal machining. CNC turning, milling, drilling, tapping, and reaming are all machining processes that shape plastic parts.
