Most common type of defects related to Plastic Parts and Assembly quality control in China
- Material Incompatibility: Issues caused by using incompatible or low-quality materials that may lead to weak parts, poor chemical resistance, or premature degradation.
- Warpage: Distortion or bending of the plastic parts due to uneven cooling or improper ejection from the mold, resulting in dimensional inaccuracies and compromised functionality.
- Splay Marks: Surface blemishes caused by the presence of moisture or volatile substances in the plastic material, resulting in visible streaks or discoloration.
- Gate Vestige: Residual marks or remnants left behind at the gate location after removal, affecting the appearance and smoothness of the plastic part.
- Poor Molding or Assembly Quality: Defects arising from issues during the molding or assembly process, including improper alignment, insufficient clamping force, or misaligned inserts.
- Defective Mold Design or Tooling: Flaws in the mold design or tooling, resulting in defects such as uneven material distribution, poor gate placement, or inadequate cooling.
- Flow Lines: Visible lines or patterns on the surface of the plastic parts caused by variations in the flow of molten plastic during the injection molding process.
- Over-packing or Under-packing: Excessive or insufficient material injected into the mold, leading to overfilled or under-filled areas within the plastic part.
- Ejector Pin Marks: Indentations or marks left on the surface of the plastic parts due to the ejection process, impacting the aesthetics and potentially compromising structural integrity.
- Sink Marks: Depressions or dents on the surface of the plastic parts caused by uneven cooling or inadequate material flow.
- Air Traps: Trapped air pockets or voids within the plastic parts, leading to weak areas or cosmetic defects.
- Contamination: Foreign particles, such as dust, debris, or impurities, embedded in the plastic during the manufacturing process, affecting the appearance and performance of the parts.
- Poor Assembly Fitment: Inaccurate mating or alignment of individual plastic components during assembly, resulting in gaps, misalignments, or loose connections.
