How do you cut plastic without cracking it?

To cut plastic without cracking it, use a fine-toothed saw, apply slow and steady pressure, and support the material firmly.

Cracking often occurs when plastic is cut too quickly, with a dull blade, or without proper support. A fine-toothed saw helps reduce stress on the material during cutting.

Always secure the plastic trim firmly to prevent movement, which can lead to uneven cuts or stress fractures. Cut slowly and evenly, allowing the teeth to do the work. Avoid forcing the blade, as too much pressure increases the risk of cracking.
