Injection Molding Troubleshooting: Common Defects in Injection Molding and Plastic Injection Troubleshooting and Solutions The purpose of this Video is to identify a broad range of molding problems that can arise in injection molded parts. This is intended as a guide only and may not be the optimum solution for every application. When troubleshooting, it is important to remember that the first step is to identify the “true” issue. When making processing changes, make one change at a time and allow two cycles, at a minimum, before moving on. If the change made does not fix the problem, then you should put that setting back to it’s original setting before making the next change. When it is necessary to request technical service, please have the following information available. 1. What type of problem, ie molding, part failure 2. Material type and lot number 3. Injection molding parameters 4. Nominal wall thickness, gate size, number of cavities 5. Material handling procedures, regrind percent used, drying times and temperatures 6. Shot size versus barrel size Visit plasticinjectionmouldingdesign.blogspot.com for the updated information. 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. The above information on injection molding defects and troubleshooting is always …
