Preform mold & Blowing mould injection molding characteristics and requirements:

PET Preform injection molding PET is a hygroscopic material, If the moisture content is too high, hydrolysis will occur under high-temperature processing. The PET molecular chain is broken and thermally decomposed to produce acetaldehyde, which has reduced mechanical properties and accelerated crystallization rate. Breaking and thermal decomposition of PET molecular chain to produce acetaldehyde, reduce … Continue reading
