The Causes and Solutions of Warping in Injection Molding

plastic products with warping in injection molding

Warpage, the injection molders‘ nemesis! It’s a common problem, especially during the fine-tuning process. Now picture a part that should match the cavity but decides to deviate, resulting in a warped section. In this scenario, even non-experts can spot the bending or twisting. So what do you do in this situation? Simple: avoid unintentional bending […]

Vacuum Voids in Injection Molding: Unraveling The Most Common Injection Molding Defect

vacuum void in injection molding

Although the plastics manufacturing business has been more productive thanks to plastic injection molding service, its finished products don’t always meet the client’s expectations. From lack of efficiency in managing the injection molding process to operating errors, production errors, and whatnot – different aspects of this production approach can lead to common injection molding defects. […]

Jetting in Injection Molding – Identifying the Cause and Troubleshooting the Defect

jetting in injection molding

Jetting occurs in a molded component when molten material is injected into the mold cavity and starts solidifying before it fills the cavity. It is a type of distortion caused by this premature solidification. Furthermore, jetting is frequently visible as a squiggly line on the surface of the final component, typically leading from the original […]

Got Discoloration in Injection Molded Parts? Here’s How To Fit It!

product Discoloration after injection molding

Injection molding discoloration is a variation from the plastic’s base color. Overheating, contamination, and faulty production could all contribute to this faulty component. The degree to which a flaw in the part’s coloring due to thermal degradation is evident varies with the severity of the degradation. To avoid this problem, it’s important to have a […]

Analyzing The Occurrence of Injection Molding Weld Lines and Their Solutions

weld lines in injection molding

Injection molding weld lines refer to a line on an injection molded part that is generated where the two halves of the mold come together. As a result, the portion has a faint, perhaps undetectable line.  This line does not normally impact the overall shape or dimensions of the item. Still, it can be seen […]

A Deep Analysis of Burn Marks in Injection Molding

burn marks

“Burn marks” are a type of flaw in injection molded parts that manifest as a blackened edge near the very end of the cavity-filling process. Air that becomes trapped in the injection mold’s cavities causes burn marks. As the plastic was pumped into the mold, it compressed the air inside the cavities to the point […]
