What is Polyethylene (PE)? CNC Machining

CNC Machining

Polyethylene (PE) is the most common plastic in use today, prized for its chemical and weather resistance. Through our UK CNC machining service, Polyethylene (PE) CNC parts can be produced as one-off prototypes or repeat batches.

It offers a high strength-to-weight ratio and good impact strength at a low cost. Typical uses include piping, packaging and chemical tanks & liners. Its quoted tensile strength of around 31 MPa gives a useful guide when sizing parts. Our team can advise whether Polyethylene (PE) is the right fit for your design, or suggest an alternative.

Parts are CNC milled or turned and available in black or white. Upload your CAD file for a quick quote on CNC machining Polyethylene (PE), with delivery anywhere in the UK. Finish options (as machined) can be confirmed when you order. Every order is checked against your drawing before dispatch.

Frequently asked questions

Is Polyethylene (PE) easy to CNC machine?

Polyethylene machines easily but is soft and has low heat resistance, so sharp tools and careful clamping are needed to avoid deformation.

What tolerances can be held on Polyethylene (PE) parts?

Plastics are softer and expand more with heat than metals, so very tight tolerances and thin walls need extra care. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.

What finishes are available for Polyethylene (PE)?

PE is usually supplied as machined, deburred or bead blasted.

What is Polyethylene (PE) used for?

Typical uses include piping, packaging, chemical tanks and liners, and wear strips.

Should I choose polyethylene or PTFE?

PE is light, tough and economical with good chemical resistance. PTFE offers wider chemical resistance, lower friction and a much higher service temperature, but it is softer and costs more.

How long does it take to make Polyethylene (PE) parts?

The typical lead time shown for Polyethylene (PE) is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
