N\u00e3o h\u00e1 necessidade de equipamento de secagem por cristaliza\u00e7\u00e3o para o tratamento do material. O PET fundido entra na sec\u00e7\u00e3o de parafuso planet\u00e1rio, onde \u00e9 uniformemente cortado por v\u00e1rios parafusos pequenos. A humidade e os vol\u00e1teis no material fundido s\u00e3o mais facilmente libertados. Em conjunto com um sistema de v\u00e1cuo, estes gases e vol\u00e1teis s\u00e3o expelidos de forma eficiente. O comprimento da sec\u00e7\u00e3o do parafuso planet\u00e1rio foi cientificamente concebido para assegurar o cisalhamento, a fus\u00e3o e a homogeneiza\u00e7\u00e3o eficazes, sem cisalhar demasiado o material. Esta configura\u00e7\u00e3o elimina a necessidade de equipamento de secagem por cristaliza\u00e7\u00e3o, poupando energia. Pode reduzir os custos de eletricidade em at\u00e9 $70.000 por ano.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. Qualidade superior do produto: As folhas de PET produzidas por extrusoras de parafuso planet\u00e1rio t\u00eam uma excelente resist\u00eancia, elevada transpar\u00eancia e menos pontos de cristal, o que as torna ideais para copos de pl\u00e1stico formados a v\u00e1cuo. O efeito de moldagem \u00e9 melhor e a taxa de rendimento \u00e9 mais elevada.<\/p>

2. Melhor qualidade para grandes clientes: A elevada qualidade das folhas PET satisfaz os requisitos dos clientes de grandes marcas, facilitando a obten\u00e7\u00e3o de grandes encomendas.<\/p>

3. Melhor do que as extrusoras de duplo parafuso: As folhas de PET produzidas por extrusoras de parafuso planet\u00e1rio s\u00e3o de melhor qualidade do que as produzidas por extrusoras de parafuso duplo, o que aumenta a probabilidade de receber encomendas.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
