Main form and solution of runner system?
Once the plastic melt enters the mold, it flows through a distribution system, also known as a runner system, and then through the gate into the mold cavity.There are two main types of runner system: cold runner system and hot runner system.
The flow inlet system is now in a cold flow inlet system, and a new flow inlet is generated at each molding cycle.This part of the plastic that forms the runner can usually be reprocessed and used for forming again.Any type of injection molding machine can use cold runner.
The circulating hot runner system is now in the hot runner system, from the nozzle to the gate
Plastic is always hot.The melt temperature in the heat channel is usually the same as that in the nozzle.Instead of heating the plastic, the heat runner keeps it cool and at the required temperature.
