2022年10月28日 · Gate blush refers to the deposition of plastic material on the gate after the injection process is complete. It's a visual imperfection that appears as light smearing or discoloration around the gates. And with a gate blush issue, time is your enemy – which means that you should know how to fix the issue as soon as it is detected.

2017年9月19日 · What’s known in the plastic injection molding business as “gate blush” or simply “blush” is a cloudy or hazy discoloration of the plastic on a finished part. It is most often found near gate locations, where material enters the part.

Plastic injection molding is a critical process used in manufacturing to produce parts with complex geometries and tight tolerances. One common issue that arises during this process is gate blush—an aesthetic defect characterized by a discoloration or hazy appearance around the gate area, where the molten plastic enters the mold cavity. This ...

If you’re experiencing blush, it could be due to the molding process, mold itself or the machine. See below for possible causes.

2019年5月3日 · Blush can be defined as a clouded discoloration normally found at gate locations, but they can be found anywhere on the part surface. These visually defective areas have very weak physical properties due to loose molecular structure. Remedies: One solution is to adjust the fill speed rate until the optimum has been achieved.

2024年9月20日 · Gate blush is a common molding defect that occurs at the gate location of injection-molded parts. It manifests as rings or ripples in the mold cavity surrounding the gate area. This defect arises when plastic material flows across the mold cavity instead of forming a fountain flow and freezing to the mold cavity.

2019年5月24日 · A molded piece with blushing is often very structurally weak due to the loose molecular structure. This can be caused by an improperly sized gate hole, a high injection speed, low injection pressure, improper melt temperature, …

A blister is a delamination that produces a bulge on the surface of the part. This bulge is usually regular in shape and can range in size from 1/8 to 10 inches. A blister is caused by the presence of gases under pressure within the substrate, forcing the skin away from the glass. Can be seen on painted or unpainted parts.

2020年2月18日 · A molded piece with blushing is often very structurally weak due to the loose molecular structure. This can be caused by an improperly sized gate hole, a high injection speed, low injection pressure, improper melt temperature, …

2021年9月24日 · Gate blush is a molding defects commonly caused at the gate location of injection molded part, It shows as rings or ripples in the mold cavity surrounding the gate area. This defect occurs when plastics material flow across the mold cavity rather than forming a fountain flow and freezing to the mold cavity.
