CNC Machining Plastic Materials
Choosing the right plastic for CNC machining requires consideration of many factors, such as corrosion resistance, machinability, weight and appearance. The plastic you choose is critical to your ultimate success.
CNC plastic machining is the current trend in manufacturing plastic parts and components. Because of the process’ ability to produce uniform, high-precision parts with tight tolerances, Allied Metal offers a wide range of plastics for CNC machining in a variety of industries. Ideal for one-off prototypes and end-user customized parts.
Excellent impact resistance, high strength, good stiffness, good Paintability and machinability, low cost.popular for prototyping
High-performance thermoplastic, very high strength, thermal and chemical resistant. Excellent thermal and electrical conductivity,low friction coefficient.
Superior impact and creep resistance, high strength and stiffness, low coefficient, excellent machinability, dimensional stability, low moisture absorption.

Process Selection Of Plastic CNC Machining
Process | Benefits | Limitations |
CNC Turning (Lathes) | Produce the parts at a lower cost compared to CNC Milling | Can only produce cylindrically shaped parts |
CNC Milling (3-axis) | Manufacturing parts with simple geometries quickly and precisely and at a low cost | Manual repositioning of workpieces reduces the achievable accuracy |
Mill-turning CNC centers | Lower cost than 5-axis CNC machinine. | Tool access and workpiece clamping design restrictions apply |
Indexed 5 Axis (3+2 ) | Eliminates the need for manual repositioning. | Higher cost than 3-axis CNC milling |
Continuous 5 Axis | Manufacture complex parts with an accuracy that cannot be achieved by any other process. | Highest cost of all CNC machining. |
Frequently Asked Questions
Plastics machining refers to the fabrication of plastics parts or products by CNC plastics machines. It is a controlled subtractive manufacturing process for cutting raw materials into a desired final size and shape. It involves milling machines, lathes, drill presses, and other CNC machines.
You can make a variety of plastics parts and products with CNC machines, from small bolts and nuts to large automotive, aerospace and defense industry parts and more.
With CNC machines, you can also create plastics artwork through etching and engraving processes.
There is really no fixed cost for plastics CNC machining. The cost range depends largely on factors such as the number of parts to be machined, their construction, materials, processes and tight tolerances.
Although there is no fixed cost reference, there are quite a few ways to reduce the cost of CNC machining, such as choosing the right materials and machining methods.
