Durante a moldagem por inje\u00e7\u00e3o, a varia\u00e7\u00e3o na contra\u00e7\u00e3o, tanto globalmente quanto ao longo da se\u00e7\u00e3o transversal de uma pe\u00e7a, cria tens\u00f5es internas. Essas chamadas tens\u00f5es residuais (consulte Tens\u00e3o residual) atuam em uma pe\u00e7a com efeitos semelhantes aos das tens\u00f5es aplicadas externamente.

Os materiais cristalinos e semicristalinos s\u00e3o particularmente propensos ao encolhimento t\u00e9rmico; os materiais amorfos tendem a encolher menos. Quando os materiais cristalinos s\u00e3o resfriados abaixo de sua temperatura de transi\u00e7\u00e3o, as mol\u00e9culas se organizam de forma mais ordenada, formando cristalitos. Por outro lado, a microestrutura dos materiais amorfos n\u00e3o se altera com a mudan\u00e7a de fase. Essa diferen\u00e7a faz com que os materiais cristalinos e semicristalinos tenham uma diferen\u00e7a maior no volume espec\u00edfico ( ) entre a fase de fus\u00e3o e a fase s\u00f3lida (cristalina). Isso \u00e9 ilustrado na Figura 1 abaixo. Gostar\u00edamos de salientar que a taxa de resfriamento tamb\u00e9m afeta o comportamento do pvT de resfriamento r\u00e1pido de materiais cristalinos e semicristalinos.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1336\" title=\"Encolhimento e empenamento\" src=\"https:\/\/web.archive.org\/web\/20130131102912im_\/http:\/\/www.moldchina.org\/wp-content\/uploads\/2011\/10\/Shrinkage-and-warpage.gif\" alt=\"Encolhimento e empenamento\" width=\"632\" height=\"404\" \/><\/p>\n<p><strong>FIGURA 1.<\/strong>\u00a0As curvas pvT para pol\u00edmeros amorfos e cristalinos e a varia\u00e7\u00e3o do volume espec\u00edfico entre o estado de processamento (ponto A) e o estado \u00e0 temperatura ambiente e press\u00e3o atmosf\u00e9rica (ponto B).
