Subsprue gate and spoke gate are two variants of the disk gate design. Subsprue gate is due to flow distribution through a cone, the flow turns at a smaller angle, thus smoothing the flow. […]
a detail need to be considered when our designer design a disk gate, because a disk gate forms a sealed space with the cavity, […]
Disk gate is a variant of direct gate design, melt material flows through the sprue with regulation to reach cavities through the gates in a disk shape, the material inflow is homogenous, […]
but direct gate also has it’s own disadvantages, at first, it is more difficult to remove the slug from a direct gate, […]
in an injection mold, there is a typical direct gate, which locates at the mold center, that is so called direct gate, it has a larger sectional area and less flow resistance. […]
I add more details, actually a gate also balances the resin filling activities amount cavities, via adjusting the gate size, the gate location, size and quantity are decided with input from the plastic part shape, appearance, […]
a gate will elevate the temperature of the cooling resin by friction as it flows through the narrow gate, […]
actually the function and purpose of a gate is to control the amount and flow direction of the melt resin, seal the resin inside the cavity until the parties sufficiently solidified enough for injection, and prevent it from flowing back.
when we design a gate for a mold, in general, it is easier to full up the cavity with a gate of a larger sectional area. But it will take a longer time to cool and seal the gate, […]
hey! Every one, actually the most important part in a feeding system is gate, because gate is the end of the runner, it is the entrance to the cavity. […]
