introduction to pin-point gate
pin-point gate is also known as needle gate, it has smaller sectional area, typically with d=0.5—1mm, it applies to plastic part materials that flow well in injection molding. […]
subsprue gate and spoke gate are two variants of the disk gate design
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
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
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, […]
