please don’t forget Edge gate
please don’t forget Edge gate, it is popularly applied to mold designs of multiple cavities for all shapes of plastic parts, Edge gate is normally located on the parting line, material is feed from the edge side.
but submarine gate has it’s special requirement in injection molding
but submarine gate has it’s special requirement in injection molding, it requires a larger flexibility to accommodate elastic deformation of the gate slug at ejection. […]
introduction to submarine gate
let me introduce a variant of the pin-point gate design, it is so called submarine gate, it can be accompanied with an automatic slug ejection mechanism. […]
Pin-point gate also has it’s disadvantages
Pin-point gate also has it’s disadvantages, pin-point gate has a smaller diameter, it consumes more injection pressure, without compensation, […]
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. […]
