Hot runners play a mission critical role in the injection molding process. Hot runner systems are a means to convey molten plastic from injection molding machines into molds, ensuring proper flow rate and pressure, while maintaining optimum temperature levels. They are essential to managing and controlling melt distribution in the injection molding process while enhancing productivity, product aesthetics/function, energy efficiency, performance, reduced part cost and reduced raw material wastage. Hot runners are integral in ensuring flawless part quality and part surface finish. Integrated into the mold and completely custom, any product design changes create the need for a new mold and hot runner system.
As the first company to introduce hot runners to the industry, Mold-Masters is recognized as the global leader in hot runner technology. We continue to build upon our extensive knowledge and experience, expanding our product line to also include temperature controllers, advanced flow control and other related products that incorporate the latest forward thinking technologies.
