Hot-runner systems have more or less become established for highly automated production of molded thermoplastic parts that are produced in large numbers.the decision to use them is almost always based on economics. Quality considerations, which played a majored role in the past, are very rare now because thermoplastics employed today are almost all so stable that they can be processed without difficulty with hot-runner systems that have been adapted accordingly.

*Economic advantage

Savings in material and costs for regrind. Shorter cycles; cooling time no longer determined by the slowly solidifying runners; no nozzle retraction required.

*Technological advantages

Process can be automated (demolding ) because runners do not need to be demolded.gates at the best position ;thanks to uniform ,precisely controlled cooling of the gate system, long flow paths are possible.
