Residence time of plastic material inside of hot runner system

Residence time of plastic material inside of hot runner system

Hello,

 

I would be glad to see the possibility to display a result showing the residence time of plastic material inside hot runner system (how many shots, for each branch of the hot runner system we need to renew material)

Indeed, some material like POM doesn't accept a long residence time because of their high thermal sensitivity. Then, in case of low shot weight, we can face critical situation.

Units of this result could be expressed in "Number of shots" then we don't integrate the notion of cycle time which is sometimes difficult to know before launching cooling analysis. In term of result, only elements corresponding to hot runner system should be displayed (same spirit than result "Throughput").

 

Thanks.

Hi Xavier,

 

Great request, and with some additional screw/barrel size machine information the residence time of the complete process cycle can be estimated.

 

Greetings,

Ramon
