If you have been troubled by a lots of problems and errors during injection molding and looking for fast ways to troubleshoot them, then do not worry, you are at the right place. We will discuss about a lot of common errors that occur in injection molding cycle.
1.) Air bubbles in Injection Molded part/Blisters on part surface
A blister is a raised area on the plastic surface, very similar to the medical condition of the same name. Many people have no clue as to what's the reason of air bubble in injection molded part.It is generally the product of too much heat on the tool or by inadequate cooling or venting. Depending on the type of tool, you can also find areas where full coverage is not working. For instance, if the injector has a flow pattern issue, it might not inject all the resin at once, allowing air bubbles to enter the molten resin. A hot runner tool might also suck air into the die because of area constriction, slowing the passage of the resin.
