A Mecmesin fornece soluções para testes em produtos ou materiais que exigem a medição de sua resistência física. Normalmente, isso envolve aplicar e registrar a força para separar, empurrar, girar ou girar.

Dividimos esses testes nos amplos tipos de tensão , compressão , textura e torque, conforme listado abaixo.

Alguns testes são mais bem executados com instrumentos menores de mesa, outros exigem estruturas de teste maiores. Tudo depende das amostras a serem testadas, seu tamanho, forma e as forças mínimas / máximas necessárias.

Ajudaremos a explicar um pouco mais sobre o que está envolvido em cada tipo de teste e orientá-lo em nossos sistemas e instrumentos de teste.

Fale com um de nossos especialistas se precisar de ajuda para descobrir qual teste você pode precisar e o equipamento mais adequado para fazer o trabalho.
