disk gate is a variant of direct gate design
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
but direct gate also has it’s own disadvantages, at first, it is more difficult to remove the slug from a direct gate, […]
introduction to direct gate of injection mold
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. […]
a gate also balances the resin filling activities amount cavities
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
a gate will elevate the temperature of the cooling resin by friction as it flows through the narrow gate, […]
the function and purpose of a gate is to control the amount and flow direction of the melt resin
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.
what will be considered when we design a gate?
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, […]
the most important part in a feeding system is 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. […]
a special runner is single cavity runner
a special runner is single cavity runner, typical single cavity mold designs use a central feed approach, […]
unbalanced runner designs have some advantages
unbalanced runner designs have the advantage of shortening runner’s total length and thus enjoy an extensive application in the industry.
