Threaded Nozzles

Synventive is an expert in threaded nozzles. They provide maximum leakage protection in high-pressure processes, safety, and ease of maintenance. 


Sliding Nozzles

When your application requires nozzles capable of shorter drop lengths and stack heights, you can easily achieve this without concerns of cantilever deflection.


Single Valve Gate Nozzles

For fast cycle applications that need excellent control, your single valve gate options will give you the necessary flow control.


Single Thermal Nozzles

High-quality molding requires precision components in every phase of your plastic melt flow. Synventive single thermal nozzles set your flow off to a perfect start.

Manifolds Built for Consistency

Synventive manifolds come in any custom shape to cover all possible hot runner injection configurations and mold concepts.




Valve Gate Actuation Solutions That Make Your Job Easier

Hydraulic, electric, and pneumatic actuators all provide the molder a unique benefit. Let us determine which is the best solution to optimize your application process. Synventive helps you plan your molding process before we ever quote your hot runner to guide you to the right actuator and pin control technology for your unique needs. We supply single actuators (hydraulic, pneumatic and electric) and actuator plates (hydraulic and pneumatic).

Hydraulic Valve Gate

Provides independent gate control for hydraulic hot runner systems. Hydraulic actuators are capable of generating high clamping forces required for casting larger parts. Ideal in cascade or sequential molding requiring excellent surface quality and dimensional stability.

Pneumatic Valve Gate

Pneumatic actuators are characterized by their fast response. This is particularly important for smaller shot weights where short injection times are required. They are compact and lightweight and are easy to maintain.

Electric Valve Gate

Electronically controlled hot runner systems offer cleanliness, precision and repeatability.

eGate®Sync electric valve gate hot runner systems feature patented technology to precisely control each valve pin. This technology is available on the Synventive valve gate nozzle sizes 12-22.

From Easy Monitoring to Full, Closed-Loop Pin Control

VMI remotely monitors your valve pin’s opening and closing speed. 

The activeGate® technologies for sequential molding are designed to facilitate perfect surface quality, dimensional stability and reproducibility of injection molded parts:

Synflow® controls the opening speed of the valve pin.
Dynamic Feed® provides completely closed loop presssure control.

Hot Halves Make Hot Runner Technology Easy

Any molding engineer knows that every component of an injection molding process and system has the potential for significant complexities. Selecting a fully assembled hot half system makes those complicated systems a little simpler. Synventive hot halves come ready to drop in and run, making installation and maintenance streamlined and simple.

Synventive hot runner systems are available pre-wired, pre-plumbed, pre-assembled or as a complete hot-half, all allowing for easy plug ‘n play installation.
