Männer Molding Solution | Hot Runner

Signature Line
Valve Gate Systems

The Signature Line with the Original Männer Cylindrical Valve Gate Technology provides impeccable surface quality, part-to-part consistency, and process reliability.
All hot runner systems are tailored and designed to meet the specific needs of our customers.

1.) Cylindrical Valve Gate: superior gate quality and perfect positioning for maximum performance, 2.) Insulating Ring: provides thermal insulation, ensures precise nozzle centering, and offers a reliable sealing function, 3.) Nozzle Heater Band: ensures uniform heating of the nozzle for consistent melt flow and improved part quality, 4.) Replaceable Valve Pin Bushing: integrated into the nozzle to prevent bending of pin during thermal expansion of manifold, 5.) Manifold Heater: tubular heating elements embedded in heat transfer cement to ensure long life and uniform temperature distribution, 6.) Leakproofed Manifold: ensures reliable, temperature-independent sealing with balanced melt flow and no stagnation, hardened block for long durability, 7.) Insulation Plate: reduces thermal radiation, 8.) Valve Pin: installation/removal possible without dismantling the mold, 9.) Pneumatic: cleanroom-compatible tandem cylinder, small unit size with high closing force.

Precentered Cylindrical Valve Gate

During the closing movement, the valve pin is first precentered by an angled guide area and then positioned perfectly in the gate orifice by means of a cylindrical guide. Nozzle and valve pin are designed to provide maximum performance and extreme durability.
- Superior gate quality
- Large gate cross section
- Minimal pressure drop
- Low shear rates
- Extreme durability wear and maintenance
- Defined opening and closing of the gate orifice
- Processing of demanding materials with narrow processing windows
- Short cycle times
- Individual heating control
- Clean room compatible
