METO Machinery is a leading manufacturer and supplier of high-precision bottle cap molds for the global packaging industry. Specializing exclusively in the design and production of advanced bottle cap tooling, we provide comprehensive, customized solutions for manufacturers worldwide. With years of technical expertise and a strong commitment to research and development, we offer state-of-the-art molds that enable customers to produce high-quality plastic caps efficiently and cost-effectively.

METO Machinery proudly presents our Heat-Resistant Bottle Cap Molds with Vertical Anti-Slip Ribbing—precision-engineered tooling solutions designed specifically for caps used in hot-fill and high-temperature applications. These caps feature vertical ribbed grip patterns that provide superior handling security, especially important when dealing with hot-filled products . Manufactured from heat-resistant materials, our caps maintain dimensional stability and sealing integrity even under elevated temperatures.
1. Heat-Resistant Material Compatibility
Our molds are optimized for high-temperature applications:
PP (Polypropylene) material – Withstands temperatures up to 120°C for hot-fill applications
Heat-stabilized formulations maintaining dimensional stability during filling
Minimal shrinkage ensuring consistent thread and sealing performance
2. Vertical Anti-Slip Ribbing Design
The vertical ribbed pattern offers significant functional advantages:
Enhanced grip security – Increases friction between fingers and cap surface
Easy opening – Particularly beneficial for hot-filled products requiring immediate handling
Consistent rib definition – Sharp, uniform pattern across all cavities
Optimized rib spacing and depth – Balancing grip performance with structural integrity
