SAN POLO DI PIAVE, Italy—HRSflow has developed a special low-height actuator for hot runner valve gate systems, specifically for the construction of stack molds.
The firm said the advantage of its compact stack mold technology is derived from the staggered arrangement of the cylinders to the side of the nozzle and the use of rocker levers to transmit the movement from the cylinder to the needle and tip solution used.
Stack molds made in this way have much lower construction heights than versions in which the cylinders and needles are aligned, according to HRSflow.
Available for PP, ABS and PC/ABS, this new technology mainly is used for big automotive parts such as bumpers and non-automotive applications such as bins or pallets.
Because HRSflow's new, low-height compact mold technology allows thinner plates, the firm said the guide and support elements can accordingly be designed smaller, which saves additional costs.
