Hello everyone,
I am a new with injection molding process and just started. Currently, I am having a problem with the molded parts, there is a join line on the surface of the finished parts. Before we have been running with same parameters and conditions but the parts still good. I dont know why this time it happened. Please kindly see the below picture:
Can anyone know and give me some advice on how to solve this problem?
Thank you in advanced!
Rob
