Computer balanced hot runner manifold system ensures uniform plastic flow

Article-Computer balanced hot runner manifold system ensures uniform plastic flow

New Yudo hot runner manifold systems are rheologically computer balanced to achieve optimal volumes and pressures throughout, and thermodynamically balanced to ensure a uniform plastic flow to all mold cavities. Thermal balance is achieved by using sheath heaters, attached to both sides of the manifold and capped by a silver-copper alloy, to maintain gate area temperature within ±1 percent. And the manifold is manufactured from a low-conductivity, powdered metal composite material that minimizes heat transfer between the manifold and the mold.

The manifold systems are available in three types of steel and three standard thicknesses. For special applications, the manifolds may be supplied in an edgeless design to maximize injection velocity or self-cleaning for use with problem plastic formulations, such as PVC and PBT. All of the systems are custom engineered and manufactured. Standard delivery is four weeks.
