20 Cavity Wide Mouth PET Preform Mould for Jar preform mould factory | DEBODI MOULD
20 Cavity Wide Mouth PET Preform Mould for Jar preform mould factory | DEBODI MOULD
DEBODI MOULD presents a high-performance 20 cavity wide mouth PET preform mould specifically engineered for jar applications – including food jars, supplement containers, cosmetic pots, and other wide-neck packaging.
Compared with standard narrow-neck preform moulds, this jar mould features an enlarged neck finish diameter (typically 38mm to 120mm), allowing easier filling, scooping, and de-molding. The 20-cavity configuration offers an ideal balance between high output and manageable mould footprint, making it suitable for medium-to-large injection molding machines.
Each mould is precision machined from premium tool steel, heat-treated for extended service life, and equipped with an advanced cooling system to reduce cycle time while maintaining preform dimensional accuracy and thread integrity.
