Mold-Master’s Symfill technology is intended to minimise core shift to improve part quality (straightness) of cylindrical, centre 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.
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.
On recent blood vial applications that leveraged Symfill technology, barrel bow was reduced by up to 90% (as little as 0.15mm) by eliminating core shift. Symfill technology is exclusively available with Mold-Masters hot runner systems.
Minimising barrel bow offers downstream processing advantages which includes enabling tubes to roll concentrically in the labelling machine; increasing final stage throughput and minimising machine downtime.
Mold-Masters is a leading global supplier of hot runners, controllers, auxiliary injection and co-injection systems. The company design, manufacture, distribute, sell and service highly engineered and customised plastic processing equipment that caters to every market.
