PET Preform Mould
In PET preform manufacturing, most production losses are not caused by machine capability, but by unstable melt flow balance, thermal inconsistency, and poor cavity synchronization.
Description
In PET preform manufacturing, most production losses are not caused by machine capability, but by unstable melt flow balance, thermal inconsistency, and poor cavity synchronization. These issues directly lead to:
- Uneven wall thickness distribution
- Gate crystallization and surface defects
- High cavity-to-cavity weight deviation
- Increased scrap rate and unplanned downtime
Our multi-cavity PET preform mold systems are engineered to eliminate these structural risks at the source, ensuring stable high-speed production, consistent part quality, and maximum line uptime for global bottling manufacturers.
