the number of molding cycles is higher than 1M repetitions, used to produce plastic parts at high volume. The molding area( including the slides and lifters in contact with melt plastic materials) is hardened. Best mold materials are used. Additional requirement are listed below: […]
there are many versions in mold grade description, actually, molds are subject to normal wear during it’s use, until the plastic part fails to meet it’s quality requirement. […]
you know, some material are difficult to mold, when we have to choose one of them to mold our product, do you know what to do? […]
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.
Pin-point gate also has it’s disadvantages, pin-point gate has a smaller diameter, it consumes more injection pressure, without compensation, […]
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. […]
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, […]
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, […]
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, […]
