    Unhappy Vented barrel Problem

    Hi, I am new in injection molding. I recently bought a toshiba press which have a vented barrel. It worked fine for a month but now melt has been flooding through this barrel. I have tried to seal it off with a high pressure sheet but it was still flooding. So, I am thinking of sealing it completely by welding. Will it be a good idea because it was beneficial in removing excess gas? Any help would be greatly appreciated.

    Hi Abhishek,
    No, do not weld anything. Find the problem why it is ... using your words 'flooding'. Contact the manufacturer or a processor to find the problem.

    Thanks Suhas for replying. I contacted the dealer. They said it is a pvc screw barrel. That's why there is vented opening. They blocked the opening with a metal block. It's working fine for now.
