CNC machining in Polyethylene
CNC machining in Polyethylene is typically done with a milling machine. A milling machine has a rotating cutting tool that removes material from the workpiece. The milling machine can be programmed to create specific shapes and sizes. The programming is done using computer software.
CNC Machining Polyethylene Materials

CNC machining of polyethylene materials can be done using either a CNC milling or CNC turning process. Both methods are effective and can produce high-quality parts. Milling is typically used for larger parts, while turning is better suited for smaller parts.
Polyethylene has a number of characteristics that make it ideal for CNC machining. It is a soft material that is easy to cut, and it has a low melting point, which makes it easy to work with. Additionally, polyethylene is resistant to most chemicals and is not affected by moisture or humidity.
Available Materials
HDPE
HDPE is a high-density polyethylene plastic that is used in a variety of applications. It is strong and durable, making it an ideal material for many different types of products.
