What is CNC plastic machining?

CNC plastic machining is a plastic parts manufacturing process by using modern computer-controlled machines. It is widely used for prototyping for functional testing and other plastic material parts are also produced using this technology. Some of the major machining operations perform during CNC plastic machining are as below:


Cutting is employed by the manufacturer to cut the plastic material to create a shape and get the desired size of the plastic. This method generates heat that can damage plastic, so this technique requires a professional operator.

CNC turning is a process where the workpiece is mounted on a spindle and then rotated and fed to various tools to gain a certain shape in plastic materials. CNC turning in plastic can carve features such as grooves, bevels, rings, threading, etc.

In CNC milling, the cutting tools rotate to remove the chips from the plastic from the stationary workpiece. There are different milling techniques for plastic techniques among the down-milling is considered best for plastic.


Drilling is used to creating small and large-diameter holes in plastic materials without damaging the structure. This process also requires a skilled operator because it is risky and produces heat during operation.


Grinding is used for surface finishing and smoother plastic products shape. This process is similar to the milling process. The milling process uses intermittent cuts while the grinding continuously cuts the plastic.

Common materials used in plastic machining

CNC machining service provider uses so many plastic materials for parts manufacturing for different industries depending upon the applications. Let’s have a look at some of the plastic materials commonly used in plastic machining.


Acrylonitrile Butadiene Styrene (ABS) is a high-strength and tough material. It is also easy to machine and has good heat resistance with well-finishing capabilities. ABS is used in LEGO toys and prototyping.


Acrylic is mostly used for the application that requires a transparent object. It is inexpensive and can easily be glued. It is scratch-resistant but requires secondary polishing after machining.


This material is a good heat and chemical resistant and maintains its rigidity in different climates. It has good machinability but it poses challenges when tight tolerances are needed.


Delrin is considered one of the most economic plastic because of its excellent machinability and low cost. It has a slippery surface which reduces friction. Delrin is hard to glue and requires secondary finishing.

Plastic injection molding is the process of injection molten plastic into a mold and then cooling it to turn it into solid-state to get the molded product. This method is used for the mass production of plastic products with complex structures. A wide range of products is manufactured using the plastic injection molding method, which can vary in size, complexity to machine, and applications. One of the widely created products through injection molding is plastic housing, because of injection molding's ability to create thin-walled plastic parts.

Rally Precision offers plastic injection molding services for applications that are used in a wide variety of industries. We are experienced in manufacturing high-quality injection molded parts with technological equipment.

Applications of CNC plastic machining

CNC plastic machining is employed for a variety of applications in different industries. Plastic capability to mold easily and take the shape without any additional work makes it the best option for CNC machining and industry to use plastic for their applications. Let's have a look at some of the applications of CNC plastic machining

Medical devices: Plastic machining is an excellent choice for medical components and equipment due to its capability to provide precision and create identical and intricates parts. Many surgical implants, sterilization trays, endoscopic probes, and cardiac implants are created by plastic CNC machining.

Automotive: The use of plastic CNC machining for automotive parts has increased due to various high-performance plastics. From the exterior of the car to the chassis many parts of automotive are created by plastic. Conditioner vent, switches, gauges, dial, and many other parts are created through plastic CNC machining.

Aerospace: The aerospace industry allows no chance for any error, this is why plastic CNC machining is used to get the precise machine parts such as rudders, fuselages, ventilation ducts and so many other parts.

Electronic Industry: There is a limitless application in the electronic industry that uses plastic CNC machining. Switches, boards, electrical insulation materials, mobile phones, and many electronic parts are produce by plastic through CNC machining.

Advantages of CNC plastic machining

CNC plastic machining has increased exponentially to its ability to provide precise and ultra-accurate plastic parts used in different industries. Let's have a look at some of the most highlighted advantages of CNC plastic machining.

Fast Prototype Turnaround: If you need a precise prototype quickly to test your product and ensure its reliability and durability then plastic CNC machining is your go-to option. It delivers faster prototypes with a short lead time.

Economical: The plastic CNC machining process is cheaper than most of the other CNC machining. Plastic CNC doesn’t require molds which is costly and takes lots of resources. Also, the overall cost incurred in plastic CNC machining is less than in other machining.

Resistant to Corrosion and Chemicals: Plastic CNC machines parts have this advantage over other metal material that they are resistant to corrosion and other harmful chemicals that reduces the life of the part.

Tight Tolerance: Plastic CNC machining is the best option if your parts require high tolerance measurements. This type of part is used in high-precision industries like aerospace making CNC plastic machining a crucial CNC machining technique.
