Our High-Cavity Food-Grade Jar Bottle Preform Molds are engineered to deliver precision and efficiency for mass-producing jar-shaped preforms used in food, beverage, and household packaging. Constructed from medical-grade P20 stainless steel (ISO 10993 compliant) with electroless nickel plating, these molds ensure consistent wall thickness and thread accuracy while meeting strict hygiene standards for direct food contact applications. The multi-cavity design (up to 96 cavities) maximizes production output without compromising on quality, making them ideal for high-volume manufacturers.
Ultra-High Cavity Density: Patented inter-cavity cooling channels enable uniform temperature distribution across 96-cavity configurations, reducing cycle times by 20% compared to standard molds.
Hygienic Surface Finish: Ra ≤0.4μm polished interior surfaces prevent residue buildup, supported by FDA 21 CFR 177.2600-compliant materials for safe food contact.
Precision Threading System: CNC-machined neck rings achieve ±0.05mm thread pitch accuracy, ensuring leak-proof compatibility with standard jar closures (28/400, 38/400).
Thermal Stability: Heat-treated to HRC 38-42, the molds maintain dimensional stability across 20,000+ cycles at processing temperatures (220-280°C), minimizing wear and tear.
Food Packaging: Used for producing preforms for peanut butter jars, honey containers, and pickling jars, ensuring clarity and structural integrity for shelf-stable products.
Beverage Industry: Ideal for crafting preforms for glass-like PET jars used in premium beverages, sauces, and dressings, enhancing visual appeal through optical purity.
Household Products: Forms preforms for detergent bottles, personal care jars, and storage containers, supporting ergonomic designs with anti-slip ribbing capabilities.
Q: What is the minimum wall thickness these molds can produce?
A: Capable of forming wall thicknesses from 1.2mm to 5mm, with uniform distribution guaranteed via melt flow analysis.
Q: How do you ensure food safety compliance?
A: All mold components undergo FDA/EC 1935/2004 migration testing, with certificates provided for each production batch.
Q: Can these molds be customized for oval jar shapes?
A: Yes, our engineering team specializes in custom geometries, including oval, square, and hexagonal profiles, with lead times of 4-6 weeks for new designs.
