12.5g Cavity
Product Features
Integrated Cavity Design Enhances Structural Rigidity
The cavity employs a monolithic precision machining process, ensuring seamless integration between the runner system and molding area. This design minimizes energy loss and turbulence during melt flow, significantly reducing defects such as flash and wall thickness variations caused by traditional split structures.
The unified design bolsters the cavity's fatigue resistance, making it well-suited for continuous operation on high-speed injection molding machines and extending the mold's overall service life.
Lightweight Optimization
Through topological optimization, the runner system reduces excess material accumulation, decreasing the cavity's overall weight and thermal mass. This adaptation meets the low-energy consumption requirements for molding ultra-lightweight preforms.
Rapid Maintenance and Flexible Customization
The cavity features standardized quick-change interfaces, ensuring seamless compatibility with mainstream injection molding machines, including Husky systems. This design shortens changeover times compared to traditional structures, accommodating flexible production scenarios involving multiple product variants.
We offer modular customization services for critical areas such as neck threads and sealing grooves, enabling swift responses to client-specific designs, including non-standard preforms and anti-counterfeiting features.
Application Scenarios
Small-Capacity Beverage Packaging
Designed for ultra-thin wall containers such as jelly cups and yogurt bottles, high-precision mold cavities ensure lightweight bottle bodies and excellent sealing performance, meeting the portability requirements of ready-to-eat food packaging.
Pharmaceutical and Health Products
Suitable for producing preforms for oral liquid bottles and dropper bottles, the mold cavities feature high cleanliness and dimensional accuracy, ensuring tight fits between bottle necks and sealing components, complying with stringent pharmaceutical standards.
High-End Cosmetic Packaging
For products like serum and spray bottles, ultra-smooth cavity surfaces enable the production of preforms with matte or glossy finishes, enhancing the visual appeal and brand value of cosmetic packaging.
