Precision 28mm PET Preform Mould for Efficient Industrial Output
- Made from high-quality mold steel and undergoing multiple heat treatments, this mold boasts high hardness and wear resistance, minimizing wear during long-term mass production and extending its service life.
- Precision structure and finely polished cavities ensure smooth and precise mold opening and closing, resulting in flawless preform molding and consistent quality across mass production.
- Optimized hot runner and cooling design ensure uniform raw material melting, minimal waste, high cooling efficiency, and faster production cycles.
- Supports custom mold cavity specifications, compatible with mainstream injection molding machines, and offers convenient installation and debugging, meeting the production needs of various bottle types.
1. Melt Injection
Melted PET at high temperature enters the mold runner through a precision injection system, distributing evenly to each cavity to ensure consistent preform dimensions and a smooth surface.
2. Molding and Cooling
The PET within the mold cavity rapidly sets, while an internal cooling system uniformly cools it, maintaining the preform's stable shape and high dimensional accuracy.
3. Demolding and Removal
After the mold opens, ejector pins or a demolding mechanism smoothly remove the preform, ensuring the finished product remains undeformed and achieving high production efficiency.
4. Continuous Cycle Production
After the mold closes, the next injection cycle begins. The multi-cavity design and rapid cooling system support efficient and stable industrial production.
