Surface blurriness in injection molded products refers to the unclear areas formed on the product's surface due to poor mold interior surfaces or excessive use of mold release agents. So, how should we address the issue of surface blurriness in products?
Regarding plastic injection molds, thorough mold polishing and improved mold release are essential steps.
Additionally, injection molding machines can also contribute to this phenomenon. How then should we identify the causes from the injection molding machine's perspective?
Overheating caused by factors such as excessively fast injection speed or high temperature settings can lead to plastic material decomposition, resulting in surface blurriness.
Setting the mold temperature too low during injection molding can also produce this effect.
Insufficient drying of the plastic material, leaving moisture within the plastic, often leads to this issue as well.
