Gate design of injection molding
hello, I need help, I have a new tool ( Blower wheel fan ) , but the gate design is not to good , and it is causing a lot of troubles to balance the parts after molding. Due the gate design , the plastics is not moving in to the tool uniformly , and this is causing bad balancing , I trying to find someone that could have experience on this kind of products and share some file and pictures to determinate if have to change my gate design or do something different .
IF this is the case, while the uneven flow appears to be a gate problem, fixing the core location will solve the problem irrespective of gate.
Of course if the gate is not into the fan axis area or it is a flat fan where core shift is not an issue this post is useless.
Also if it is a flat type fan, you might have eneven cooling also causing more restriction to one side. Your support pillars might also be inadequate.
It really epends so much on what6 has not been disclosed.
