Mold-Masters takes Electric Valve Gating to the next level |
Frankfurt, Germany
Dec 3, 2008
Until now, electric valve gating has been limited by factors such as electric piston overheating, limited cycle times, slow pin actuation, high price and lack of closing forces. At the EUROMold Show December 3 to 6, 2008, Mold-Masters announced the introduction of an electric valve gate (EVG) for the hot runner marketplace that has superior performance characteristics to pneumatic systems.
Compared to conventional pneumatic systems and other competitive electric valve gate systems, Mold-Masters new proprietary electric valve gate has a very high closing force which, in some cases, is almost two times higher than pneumatic actuators. The unique design of the actuator allows for pin movement in less than 0.1 second and overall molding cycles below 1 second. EVG is up to 90% 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 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.
EVG systems can be used in many applications such as consumer electronics, medical, packaging, and consumer goods.
The simple touch screen Electric Valve Gate (EVG) controller now allows the molder the ability to easily sequence the valve gates or shut-off a given cavity without altering tip heats - something that is not possible on fluid based systems that are co-joined by gun-drilled lines.
EVG systems are available in 75 and 55 mm piston sizes to allow for tight pitch applications. |
