About This Product

The Mini Runner System was born from the well-known fact that even with an open nozzle, resin may not leak depending on the type of resin.

The MSK mini runner system has a structure in which the nozzle tip is always in contact with the mold, and this allows heat to escape to the cold side of the mold, lowering the nozzle tip temperature. The surface cools and hardens, forming a thin resin film regardless of the resin. This membrane does not cause drawling even under exhaust pressure or residual pressure, and is easily destroyed at the start of the next injection to start injection filling, making continuous molding possible.

In addition, the MSK Mini Runner System can handle all types of resins, including super engineering plastics and highly fluid resins, as well as resins that could not be molded using conventional open nozzles.

Mini runner features
■High cost-effectivenessMini runner systems can be introduced at a lower cost than hot runner systems, so they are attractive in that they are cost-effective even for short-term molds.

■Compatible with various resinsIt can handle resins such as super engineering plastics and highly fluid resins that cannot be molded with conventional open nozzles, making it highly versatile and improving the flexibility of production lines.

■Reduction of cycle timeThe mini-runner system reduces shot weight and reduces cycle time, leading to increased productivity.

■Easy to adjust mold balanceEven a mold with poor injection balance can be modified to a well-balanced mold by using the mini-runner system, which leads to stable quality.

■Improving energy efficiencyMini runner molds are environmentally friendly because they eliminate resin waste, shorten cycle times, and require less energy to produce.
