O isopor é um material versátil e flexível. Mas ao se tentar serrar ou cortar com uma faca comum, ele pode se despedaçar e soltar muitas bolinhas.

Um jeito mais simples de cortar isopor é aquecendo uma faca quente. Preferencialmente uma de cabo de madeira, para evitar o calor na mão.

Outra maneira é usando um fio de Níquel Cromo de 0,8mm. Fios mais finos tendem a queimar o molde, formando dentes. Mais grosso não esticam adequadamente.

Aprenda a Como Cortar o Isopor

O isopor é um material versátil e flexível. Mas ao se tentar serrar ou cortar com uma faca comum, ele pode se despedaçar e soltar muitas bolinhas.

Um jeito mais simples de cortar isopor é aquecendo uma faca quente. Preferencialmente uma de cabo de madeira, para evitar o calor na mão.

Fio dental também é ótimo para fazer cortes em placas bem finas de isopor. Basta segurar a placa com uma mão e puxar o fio dental.

Outra maneira é usando um fio de Níquel Cromo de 0,8mm. Fios mais finos tendem a queimar o molde, formando dentes. Mais grosso não esticam adequadamente.

Para controlar a tensão elétrica no fio, utilizo um regulador (dimmer) ligado diretamente à tomada na parede.

Faça marcações no dimmer para calibra-lo para os próximos cortes. A prática, neste caso, é a grande aliada.

Lembre-se de isolar-se do fio, para evitar tomar choque e também para evitar por fogo. O máximo de perigo é estourar o fio (Não deixe-o ficar muito vermelho).
