with the MMS, Männer says. The company also developed a new hot runner


configurator that allows for 2-, 4- and 8-drop hot runner systems designed with the best-selling nozzles from Männer or its sister company Synven- tive to be created in minutes using 3D data. The hotrunner.shop configurator offers step-by-step instruction that allows customers to generate customised 3D data easily and quickly. The configurator offers an application check, which includes a follow-up with an application engineer when the application is outside of guidelines. The configurator draws on a material database of more than 12,000 resins. Synventive developed a new compact and

Multi-drop Männer expanded its Packaging and Slimline product range with additional valve gate nozzles, according to Lean-Sophie Haack, Event & Commu- nication Specialist for Moulding Solutions. Män- ner’s Packaging range of nozzles for high-speed moulding is complemented by the new MCP-EP, a high-throughput nozzle for high-speed, thin wall applications. MCN-EP is an unscrew type nozzle with a small diameter and permanently centered valve gate pin. The design of the patent pending nozzle tip facilitates high-precision gating and enables the correction of tip protrusion without reworking, the company says. Männer also expanded its Männer Multi-drop


System (MMS) of small multi-drop configurations with a new side gate design. The MMS line is designed for processing parts with low shot weights using technical resins in applications with tightly spaced mould cavities. The system can be designed for use with 2- to 4-point nozzles avail- able with different axis spacing. Standard, wear- proof and special material nozzle types are offered

Thermoplay also updated its 3PK valve gate which is designed for performance applications. The sealings have been improved and the pistons and cylinders have been made smaller while maintaining excellent gate quality and use in fast cycle applications. At the K show in 2022, Thermoplay introduced two nozzles to its TFS series of open nozzles for side injection applications. The new nozzles handle larger part volumes. The company also created nozzles for a 45-degree gate to produce conical parts and has developed multi-tip nozzles for small parts that are gated with several gating points, the company says.


cost-effective electric valve gate that complements its eGate system. Its new eGate Sync features plug-and-play installation and a simple user interface. The design of the electric valve gate improves quality by increasing shot-to-shot consistency, along with significant energy savings compared to hydraulic systems, the company says. The configurator will be extended to incorporate top selling nozzles from Thermoplay, it says. Yudo extended its electric valve pin control technology with a new version that works without a controller required. At last month’s Fakuma show, Luca Nante, Key Account Manager for Packaging in Europe, showed the new YUDrive system in which each servo electric valve pin is connected to its own operating system and can be configured for dynamic opening and closing movements. Yudo configures up to two preset movements of the electric valve pin for the opening and closing strokes, according to user requirements. The pin can open slowly initially followed by fast movement to complete the stroke, or open fast followed by a slow finishing stroke. Closing movement of the pin can also be configured for fast/slow or slow/fast movement, says Nante. Yudo configures the stroke length or time for


each stage of the two-stage opening or closing valve pin movement. Moulders can reduce weld lines or pressure lines on the moulded part by actu- ating the pin in a two-step sequence, Nante says. The movement of the servo pin is triggered by a


signal from the injection moulding machine. That signal can be based on screw position or time, or a pressure sensor or external timer. YUDrive requires 48 V for activation. Yudo also offers YUDrive II which operates with the use of a standalone controller. That model offers up to 16 drops of control and comes with a resin purging function built in. The controller can connect with mobile devices or laptops and can
