How to cut PVC

How to cut PVC

PVC is easy to cut and saw. You can cut sheets up to 5 mm thick with Stanley knives (box cutters). As well as the necessary protective equipment, use a steel rule to cut straight. Move the knife along the cutting line in three steps; it is better to cut lightly a few times than firmly at once. This is better both for safety and the cutting line. Foamed PVC, also called foam board, can often be cut in one cutting movement. You can also cut foamed PVC on a sheet metal cutting machine or cut it on a plotter machine. The maximum sheet thickness depends on the capacities of the cutting or plotting machine. Contact the machine manufacturer for the maximum sheet thickness of foamed PVC. Cutting with a waterjet (water cutting) is suitable for both hard and foamed PVC.

Sawing hard PVC

PVC can be sawn with different types of machines: with band saws, circular saws, plate saws and jigsaws. The key to a good cut is a high cutting speed (rotation speed) and a gentle feed through the material. It is very important that the sawing machine has a dust/chip discharge. We offer the following guidelines for the various types of saw:

Jigsaws: A connection for dust extraction is necessary. Take a saw blade for plastics. Use medium to high speed and gently move the saw through the material. Good guidance and support of the sheet is necessary so that it does not vibrate during cutting.

Circular saws: Choose an HSS saw blade with alternating teeth, suitable for plastics. The clearance angle of the teeth must be between 10 ° to 15 °, the rake angle up to 6 °.

Band saws: Choose a fine-toothed saw blade, with tooth pitch approximately 2.5 millimetres. Maintain a high cutting speed, but ensure a smooth passage of the PVC sheet along the saw. Good guidance and support of the sheet is necessary.
