“Icy River” molds represent a specialized category of injection tooling designed for products associated with cold consumption and preservation — from ice cream containers and ice cube trays to cold beverage packaging, ice pop makers, and ice maker components. This sector demands molds that excel in food-grade safety, rapid cooling cycles, high-cavity productivity, and exceptional release performance, ensuring flawless part quality even in the most demanding production environments.

Much like the cold, flowing water of an icy river, these molds must enable smooth, continuous production. They must also adapt to the growing global emphasis on sustainability. Consumer demand for creative designs, combined with commercial applications like creating crystal-clear ice balls or themed ice molds, pushes the boundaries of conventional molding. Our molds are engineered to handle these challenges with high-speed, thin-wall molding capabilities, sophisticated unscrewing mechanisms, and corrosion-resistant materials suited for low-temperature or humid manufacturing environments

Product Features

• High-Speed Thin-Wall Molding:Optimized for injection speeds up to 500 mm/s and dry cycles as fast as 1.5 seconds, maximizing output for high-volume seasonal demand
• Superior Release Performance:Precision-polished cavity surfaces (Ra ≤ 0.025 μm) and optimal draft angles ensure easy part ejection without sticking, critical for frozen confections
• Corrosion-Resistant Construction:Utilizes stainless steel grades like S136 and 2316 to withstand moisture and aggressive cleaning agents in food production environments
• Multi-Cavity Configurations:Supports high-cavity layouts (up to 64 cavities) for high-volume production, consistent with commercial PET preform systems used in the beverage industry
• Advanced Demolding Mechanisms:Incorporates specialized slides, lifters, and ejector systems (including inclined guide posts and auxiliary cores) to handle complex parts like ice maker shells and bottle-neck clamping pieces
