|---|---|---|---|---|---|---|---|
| PET | 1.4-1.6 | 55-75 MPa | 55-60 MPa | 50-300% | 90-110 MPa | Good | Fair |
PET CNC Machining
PET CNC machining is a process that uses computer-controlled machines to cut and shape plastic parts.
PET, short for polyethylene terephthalate, is a tough, clear plastic that’s easy to work with. The machines use spinning tools to carve the PET into different shapes, following a design made on a computer. This method is great for making precise parts quickly, whether you need just one or many.
PET is often used because it’s strong, doesn’t absorb much water, and resists many chemicals. It’s popular for making things like food containers, car parts, and medical devices. CNC machining PET allows for complex shapes and smooth finishes that are hard to achieve by hand.
available surface Finishes for CNC machined PET Parts
- As-Machined: The natural finish left by the CNC machining process, often with visible tool marks and a semi-smooth surface.
- Polished: A smooth, glossy finish achieved by polishing the surface. This enhances the clarity and appearance of the PET part.
- Bead Blasted: A matte finish created by blasting the surface with small beads. This provides a uniform, slightly textured appearance.
- Textured: A specific pattern or texture is applied to the surface, often for aesthetic or functional purposes, such as reducing glare or improving grip.
- Laser Marked: A surface finish where laser technology is used to mark or etch the part with text or patterns.
CNC Machining PET FAQs
PET offers excellent dimensional stability, low moisture absorption, and good electrical insulation. It’s highly resistant to chemicals and wear, making it ideal for parts that require durability and precision.
Yes, PET can be machined to tight tolerances due to its rigid and stable structure, making it suitable for precision applications in industries like electronics and automotive.
PET is best machined using milling, turning, and drilling processes with sharp, precise tools to achieve a smooth finish and avoid excessive heat buildup that can cause material deformation.
PET can be sensitive to heat, which may lead to melting or warping during machining. Proper tool selection and coolant use are essential to maintaining material integrity.
Yes, PET is often combined with materials like glass fibers for enhanced mechanical properties, but machining such composites may require adjustments in tool selection and machining parameters.
