AT-Machining offers a diverse range of plastic for CNC machining, with applications in a variety of industries. Ideal for one-off prototypes as well as end-use custom parts.
Choosing the proper plastic for CNC machining involves considering some factors. The plastic you select is critical to the final success. For example, the plastic may need to be resistant to high temperatures or bend or break under pressure. When choosing the correct plastic, corrosion resistance, workability, pricing, weight, and visual look all play a role.
Good chemical resistance; easy to weld and machine; durable.
Plastic CNC machining is a subtractive manufacturing process that involves placing a solid block of plastic material against a mobile cutting tool to remove materials from it. A digital design file guides the path of cutting tools, ensuring the final product takes the desired shape.
CNC plastic machining is the current manufacturing trend in making plastic components and parts. This is due to the ability of this process to create parts with uniform, high precision, and tight tolerances.
Plastic turning is a manufacturing process that spins the workpiece to allow a stationary cutting tool to precisely remove excess material and create shapes as per the desired design.
Plactic CNC milling is a machining process that the workpiece is mounted onto a table, and the cutting tool is held in place by a rotating spindle to remove plastic material from multiple axes.
There are several reasons why plastic manufacturers choose CNC plastic machining over other forms of plastic manufacture. Here are some advantages of plastic CNC machining
The type of plastic fabrication process used for machining depends on several factors. So, when do you use CNC machining as opposed to 3D printing?
3D printing large plastic parts are not feasible because it takes a long time, sometimes hours. However, fabricating large parts using a CNC mill only takes a few minutes.
If you design a component in a material such as PVC, POM, PEI, or PEEK, 3D printing is not an option. Instead, these materials can be sourced in blocks and bars for CNC machining.
CNC machining is the better choice for manufacturing precise parts with intricate details because it can achieve an extremely tight tolerance down to ±0.005mm, but 3D printing only can achieve ±0.1~0.5mm.
When parts require tiny details that cannot be made with 3D printing, CNC machining is the best choice. Small details, such as intricate optical patterns, can have a radius as small as R 0.05 mm, and this level of detail is difficult to achieve with 3D printing.
CNC machining is a popular method for fabricating high-precision plastic parts used in the medical industry, such as medicine dispenser components, handles for surgical tools, and components for medical devices. There are many medical-grade materials available for CNC machining.
CNC-machined plastics are ideal for producing parts used in the food and beverage industry, such as valves, nozzles, and seals. These parts are used in food processing and packaging machines.
The semiconductor industry relies on plastic CNC machining to create precise parts from high-performance engineering plastics. These intricate parts require extremely tight tolerances and good surface finishes that would not be possible without the precision of plastic CNC machining.
Plastic CNC machining is one of the best ways to manufacture high-performance CNC-machined plastic components for use in the aerospace and automotive industries. The reason is that plastic machining can fabricate most plastic materials that meet the strict regulations and requirements needed by these industries.

Plastic CNC machining is a process of using computer numerical control (CNC) machines to shape and cut the plastic material into the desired shape. This technique is highly accurate, allowing for the production of complex designs with intricate detail or complex geometries.
The cost of plastic CNC machining depends on many factors, including the material used and the expertise of the machining services provider or CNC milling machine shop. However, the cost could be as low as $10 per hour.
The best plastics for machining include; Acetal, PEEK, and PVC. The reason is that they have a high degree of machinability and offer good dimensional stability.
Also, these different plastics are readily available at a low cost and have the potential to resist chipping and melting. They are also impact-resistant and have high impact strength.
