Fitting the maximum number of cavities within the smallest possible space – Männer's Slimline nozzle demonstrates its outstanding abilities day after day in high-speed, high-cavitation systems for the production of complex small or medium-sized plastic parts, Männer says. Featuring a slim design with a nominal nozzle diameter of only 8 mm, the valve gate nozzle is designed for applications with tight spacing or low accessibility such as direct injection close to core pins or inside injection.

Reliable and gentle processing of PA, PBT, POM, and LCP

At Fakuma 2015, the Männer Group in Bahlingen, Germany was showcasing further developments of its Slimline nozzle to benefit the production of technical parts made of engineered resins, such as semi crystalline or liquid crystalline thermoplastics (PA, PBT, POM, and LCP). The Slimline nozzle has an improved temperature profile along with special-designed nozzle tips for these applications, allowing for longer L-dim - ranging from 39 mm to 164 mm, the company explains.

With the introduction of this added capability, Männer is focusing on ensuring reliable production of functional parts for the automotive, electrical, and electronics industries.

The Slimline nozzle combines heating and temperature distribution in a single component: the newly developed temperature-control element. According to the company, the patent-pending nozzle temperature-control element precisely distributes power over the entire nozzle length, ensuring optimum thermal balance. The integration of these functions eliminates the need for a heating coil and a heat-conducting shell – making it possible to gain 1 mm of space for a more robust nozzle design, while maintaining the same slender installation dimensions.

Furthermore, the more robust nozzle body enhances not only the pressure resistance of the slender valve gate nozzle, but also permits a nozzle design featuring a screw-on tip. The advantages: Männer's Slimline is now available in nozzle lengths ranging from 79 mm to 204 mm in 25-mm increments, the supplier notes. The nozzle tip also houses the pre-centering device for the valve pin, and the easy-to-replace screw-on tip enhances ease of maintenance.
