Automotive mold hot runner occupied a very big portion in hot runner market, more and more main engine plants always adopt hot runner to inject automotive parts. Due to the strong competition in the 21st century, product requirement become more demanding, the testing of processing become particularly important. when choose supplier of automotive mold hot runner they have high standard of hot runner professional degree.

Here I list a simple analysis: auto part included interior trim part and outer part. relatively speaking, interior trim part has low requirement of its appearance, but it has strict requirement to the assembling parts. We always make use of open gate hot runner system, small product will choose pinpoint gate nozzle, direct gate nozzle will be chosen by big products certainly. What’s more, some undemanding parts can use cold runner expect luxury vehicle. Outer parts has high demand of welding line problem don’t exclude a small number of interior trim part. Some key position must not be allowed to exist welding line. At this time, hot runner manufacturer will use sequence valve gate hot runner system to adjust welding line position.

Many clients vibrated between open gate and valve gate. Of course, open gate has an abuse that in case welding line turn up, there is no method to adjust it. But sequence valve gate is much more advanced than open gate. Of course, valve gate system is much more expensive than open gate, so benefit-risk balance is very important.
