Plastic Packaging Engineer, HDPE Bottle Structural Design

A comprehensive structural design and 3D CAD modeling project for a High-Density Polyethylene (HDPE) bottle, engineered for optimal durability, material efficiency, and consumer ergonomics. This project bridges the gap between aesthetic product design and rigorous mechanical engineering, ensuring the packaging is both visually appealing and fully optimized for the blow molding production pipeline. Key Engineering Features Optimized Wall Thickness: Engineered precise wall thickness to maintain structural integrity and impact resistance while minimizing plastic usage to reduce mass-production costs. Precision Neck & Threading: Highly accurate mechanical modeling of the neck finish and thread profiles to ensure a leak-proof seal and seamless cap integration. Design for Manufacturability (DFM): Carefully calculated draft angles, parting line placement, and undercut avoidance for efficient ejection during the injection blow molding process. Rapid Prototyping Ready: CAD files fully drafted and prepared for 3D printing, allowing for physical evaluation of ergonomics, volume accuracy, and mechanical fit prior to full-scale tooling. Technical Specifications Primary Tools: SolidWorks, AutoCAD Material: HDPE (High-Density Polyethylene) Focus Areas: Structural Analysis, DFM, Fluid Volume Optimization
