Electric Valve Gate Hot Runner System
Once the pressure in the accumulator is below set point the hydraulic pump replenishes the accumulator.
Electric valve gate hot runner system. Embossed doors not embossed bumpers luggage. Pneumatic valve gate sequencer. This control is based on pump on demand technology. Today the mold masters hot runner product line has expanded and represents the broadest selection of hot runner products from any manufacturer.
Compatible with both commodity and engineering grate resins accu valve meets the demanding needs of many medical packaging personal care and many other applications. This technology is recommended for medium to large size parts obtained through sequential moulding such as. When the valve gates are fired oil is used from the hydraulic accumulator. Because the needle drive is positioned in the clamping plate the total height of the system is similar to a normal hot runner system see figure 7.
Egate electric valve gate hot runner systems feature patented technology to precisely control each valve pin s position acceleration velocity and stroke allowing processors the unique ability to control the flow rate out of each nozzle gate at any time during the fill process. Hydraulic valve gate sequencer. Individual stem actuation and plate actuation. This technology is now available on all synventive hot runner nozzle sizes.
We ve come a long way since that first design. Standard injection gated manifolds. The standard valve gate is of importance when a low system height is required. The right device to reduce flowmarks in sequential filling.
Within these groups valve gate hot runners are available in pneumatic hydraulic and electric models each of which has its own advantages and disadvantages for certain types of applications. Egate electric valve gate hot runner systems feature patented technology to precisely control each valve pin s position acceleration velocity and stroke allowing processors the unique ability to control the flow rate out of each nozzle gate at any time during the fill process. Electric valve gate system. Flexspeed technology has been developed to avoid the generation of flowmarks on the part surface generated by the instability of the plastic flow front in sequential moulding.
The pump then rests until oil is needed again. Throughout our history mold masters innovations have continued to drive the plastic industry forward. Dual capability valve gate sequencer. However when using this method the manifold of the hot runner system must be specially adjusted to the valve gate.
