Mold-Masters' SYMFILL Technology reduces barrel bow by up to 90%

Mold-Masters, a leading global supplier of hot runners, controllers, auxiliary injection and co-injection systems, has leveraged SYMFILL Technology on recent blood vial applications. The barrel bow was reduced by up to 90% (as little as 0.15mm) by eliminating core shift.


Mold-Masters enhances part quality by minimizing barrel bow.

SYMFILL Technology is exclusively available with Mold-Masters hot runner systems. It minimizes core shift to improve part quality (straightness) of cylindrical, center injected components having an aggressive L/D ratio. It achieves this by allowing the melt to enter the nozzle runner channel from multiple sides as opposed to the single-entry point of traditional designs.


Minimizing barrel bow offers many downstream processing advantages which include:

  • Tubes roll concentrically in the labeling machine

  • Increases final stage throughput

  • Minimizes machine downtime


Examples of such components that would benefit from this technology include blood tubes, needle shields, over caps and other similar parts from the medical, cosmetic and stationary industries.
