When a new project is still in the conceptual design phase, it is often overlooked how the stack-type hot runner molds are selected because many mold designers are not familiar with the technology. Compared with the usual single-sided injection mold, the use of laminated hot runner mold can make the plastic melt evenly distributed to two separate sub-surface, so that the production of injection molding machine more than doubled.

Laminated hot runner molds can increase the yield of the injection molding machine

Parts production doubled

Laminated hot runner mold technology is not by adding more cavity to increase the size of the mold, but to maintain the original mold size and injection molding machine size conditions, add a second layer cavity, with the first layer The cavity is parallel. The injection, compression and cooling times of the stacked hot runner mold are maintained at the same level and only the opening and closing times of the mold are increased throughout the duty cycle.

Reduce the price of parts

The price of the part depends on the working hours of the injection molding machine, and this cost has a direct relationship with the clamping tonnage of the injection molding machine. Compared with single-sided molds with the same number of mold cavities, the use of laminated hot runner molds requires only about 50% clamping tonnage. Such as a set of 8 8 cavity of the laminated hot runner mold can replace a set of 16 cavity design of single-sided mold, and its required injection molding machine only half the size, that is, the use of its mold is smaller, The size of the injection molding machine is also small.

However, its production capacity and production are the same as 16 molds. But a set of 16-cavity single-sided die need to run on a 600t injection press, and a set of 8 8 cavity cavity die only a 300t injection press can be, and this can make injection molding machine The work rate decreased by 43%.
