1. Increase the injection volume, which is more suitable for the production of multi-cavity products. Tailored according to different requirements, it is more advantageous for the production of packaging, deep cavity and high speed PET preform products.
2. PET special screw signifi cantly increases the melting speed and injection volume,reduces the plasticizing temperature, effectively improves the shrinkage of the preform and improves the transparency.
3. Increase the thimble force and the ejection stroke, which is more suitable for deep cavity PET preform molding.
