Key Features

1. High-Efficiency 8-Cavity Balanced Multi-Cavity Design

  • Symmetrical 8-cavity layout with optimized runner flow path, achieving uniform melt filling across all cavities, greatly boosting hourly output and reducing the unit packaging cost for cosmetic mass orders.

  • Balanced injection pressure avoids inconsistent shrinkage, weld lines and dimensional deviation between cavities, guaranteeing high consistency for cosmetic jar batch production and interchangeable matching with cosmetic lids.

  • Built-in reliable side core-pulling mechanism precisely forms the bottom positioning buckle structure, enabling stable stacking, anti-slip placement and tight sealed assembly for cosmetic packaging jars.

2. Mirror Polished Cavity for Premium Cosmetic-Grade Appearance

  • Mold core and cavity adopt 718H / NAK80 pre-hardened mold steel with high-precision mirror polishing treatment, effectively eliminating bubbles, flow marks, foggy surfaces and tiny blemishes, presenting crystal-clear translucent texture for cosmetic containers.

  • The smooth seamless inner and outer surfaces leave no sanitary dead corners, convenient for high-temperature disinfection and cleaning, complying with cosmetic packaging hygiene standards to avoid bacterial contamination of skincare raw materials.

  • Available for multiple cosmetic-grade transparent plastics including PP, PET, PCTG, which can realize frosted, translucent and fully transparent appearance effects to match high, mid and low-end beauty brand positioning.

3. Stable High-Rigidity Mold Structure for Continuous Mass Production

  • Adopts standard high-rigidity mold base paired with high-precision guide pin & sleeve positioning system, resisting high-frequency mold opening and closing force during long-term multi-cavity production to prevent mold deformation and product flash defects.

  • Equipped with synchronous multi-point spring ejection structure, ensuring smooth scratch-free demolding of 8 cosmetic jars in one cycle, protecting the high-gloss surface of cosmetic packaging from scratch damage.

  • Uniform circulating cooling channel layout shortens molding cycle, improves production efficiency, and effectively restrains thin-wall cosmetic jar warpage, shrinkage and deformation.

4. Customized Cosmetic Packaging Solution with IP Protection

  • Support personalized customization of jar capacity, diameter, wall thickness, buckle structure and thread design; brand LOGO, pattern and batch code can be directly engraved on the mold cavity to realize exclusive cosmetic packaging.

  • All matched cosmetic raw materials can provide FDA, RoHS and cosmetic packaging safety certification documents, supporting global brand export and beauty product market access audit.

  • We sign strict NDA confidentiality agreements for all customer cosmetic packaging designs, protecting your exclusive packaging intellectual property and brand competitive advantages.
