Valve-Gate Sequencer Controls Mold-Filling Sequence
PCS Company has introduced the Polimold Valve Gate sequencer to control the opening and closing of hot runner valve-gate pins.
PCS Company, Fraser, Michigan, has launched the Polimold Valve Gate Sequencer, providing injection molders with more precise control of the mold-filling sequence when using valve-gate hot runner systems.
PCS says each module of the Polimold Valve Gate Sequencer controls two zones, with the option to control up to 14 zones. In addition, multiple sequence injection capabilities enable the valve gates to be opened and closed simultaneously or individually.
Modular and compact, the Polimold Valve Gate Sequencer can be used for both pneumatic and hydraulic valve-gate systems, enabling molders to move weld lines on cosmetic surfaces or to improve part strength.
It can also eliminate flash and short shots with precisely controlled material flow, while reducing the amount of clamp force needed. Cosmetically, sequential valve gates can also decrease flow marks on the part surface.
