Product Overview
This is a high-efficiency custom plastic injection mold designed for mass production of PP-based bottom plastic components. Featuring a 1×2 cavity configuration, integrated hot runner system, and precision-polished mold surfaces, this tooling delivers consistent, high-quality parts with exceptional surface finish and dimensional stability. Ideal for medium-to-high volume production, it is engineered to maximize output while minimizing cycle time and material waste.
Key Features
✅ 1×2 Cavity Balanced DesignThe 1×2 cavity layout ensures balanced melt flow and identical part quality for both components in every shot, doubling production output without compromising precision. This configuration strikes the perfect balance between efficiency and cost-effectiveness for bottom plastic component manufacturing.
✅ Hot Runner System for PP MoldingBuilt with a dedicated hot runner system optimized for polypropylene (PP), this mold eliminates cold runners, drastically reducing material waste and cycle time. The system ensures uniform melt distribution to both cavities, preventing common defects like short shots, flow marks, and inconsistent filling.
✅ Polished Mold Cavities for Premium Surface FinishThe mold cavities are precision-polished to a high-gloss finish, resulting in defect-free, smooth surfaces on the final PP components. This eliminates the need for secondary finishing operations, reduces post-processing costs, and ensures the bottom parts meet strict aesthetic requirements.
✅ Optimized for PP Material PerformanceEngineered specifically for polypropylene (PP) resins, including homopolymer and copolymer grades, the mold accommodates PP’s unique processing characteristics—such as low melt viscosity and fast crystallization—to produce rigid, impact-resistant, and dimensionally stable bottom plastic parts.
✅ Robust Mold Construction & LongevityConstructed from high-grade mold steel with precision CNC machining and heat treatment, this tooling offers exceptional durability and wear resistance. The heavy-duty guide pillars, ejection system, and mold plates ensure stable, repeatable performance through hundreds of thousands of production cycles.
