HOT RUNNERS
Canadian Plastics
Mold-Masters is introducing an electric valve gate (EVG) for the hot runner marketplace that offers closing force almost two times higher than some pneumatic actuators.
Mold-Masters is introducing an electric valve gate (EVG) for the hot runner marketplace that offers closing force almost two times higher than some pneumatic actuators.
The design of the actuator allows for pin movement in less than 0.1 second and overall molding cycles below one second.
EVG is up to 90 per cent more energy efficient than traditional actuators for valve gates and is ideally suited to cleanroom applications, as it produces almost no particulate pollution.
In addition to the energy savings, plate costs are reduced on EVG systems because there is no requirement for gun-drilling technology showcase of air or hydraulic channels, plugging of the gun-drilled lines, or need for water/ hydraulic fittings.
The EVG system is standardized and modular in design so it can easily be removed and used on future molds.
The EVG touch screen controller allows the molder the ability to easily sequence the valve gates or shut-off a given cavity without altering tip heats.
EVG systems are available in 75 and 55 mm piston sizes to allow for tight pitch applications.
