Master Releases New Hot Runner Technology that Reduces Warpage by 90%

The world's leading hot runner company, Mold-Masters, recently launched a hot runner SYMFILL technology that can be applied to injection molding of blood collection tubes
.
This technology reduces the warpage deformation (barrel bow) by 90% by eliminating the core offset, which can be improved from 1.
5mm to 0.
15mm
.

According to reports, SYMFILL technology is dedicated to Master hot runner systems
.
It minimizes core offset to improve part quality (straightness) in cylindrical, center-injected parts with positive L/D ratios
.
It allows the melt to enter the nozzle runner channel from multiple sides rather than the single entry point of traditional designs to achieve this function
.

According to Master, the reduction in warpage yields numerous downstream processing benefits, including: concentric rolling of the tube in the labelling machine, increased throughput in the final stage, and minimal machine downtime
.
The technology can be applied to blood collection tubes, needle shields, caps and other related components of cosmetic packaging and stationery in the medical industry
