Injection Molding Weld Line: Its Causes, and How to Avoid It
网页2023年12月14日 · A weld line, often referred to as a knit line, represents the junction where two flow fronts converge during the molding process. This line typically emerges when these fronts are unable to seamlessly merge or “weld” together.
注塑最头疼的问题——熔接痕(Weld Lines)缺陷分析及排除方法
网页什么是熔接痕 (Weld Lines)？. 熔接痕 (Weld Lines)，在注塑成型制品的众多缺陷中，熔接痕是最为普遍的，除少数几何形状非常简单的注塑件外，发生在大多数注塑件上（形状通常为一条线或V形槽），尤其是需要使用多浇口模具和嵌件的大型复杂品。. 熔接痕不仅使得 ...
Weld line - Wikipedia
网页In manufacturing, the Weld line or Knit line or Meld line is the line where two flow fronts meet when there is the inability of two or more flow fronts to "knit" together, or "weld", during the molding process. These lines usually occur around holes or obstructions and cause locally weak areas in the molded part. [1]
注塑熔接线：产生原因以及如何避免 - RapidDirect
网页熔接线，通常称为熔合线，代表成型过程中两个流动前沿汇聚的交汇处。. 当这些前沿无法无缝合并或“焊接”在一起时，通常会出现这条线。. 熔接线通常出现在孔或障碍物周围，表明模制部件内强度降低的区域。. 机械师普遍使用的关于熔接线的另一个术语是 ...
熔接线和熔合线有什么区别，为何如此重要？ - RJG, Inc.
网页2020年7月7日 · 三个经常混淆的术语是熔接线（weld line）、熔合线（meld line）和熔接缝（knit line）。 熔合线和熔接缝实际上都是不同类型的熔接线。 让我们回顾一下是什么导致了熔合线和熔接缝的缺陷，它们是如何影响零件耐久性的，以及它们之间的区别是什么。
Weld Lines – EngineeringTechnology.org
网页Weld lines are a common defect encountered in injection molding, characterized by visible lines or seams on the surface of molded parts. These lines occur when two or more molten material flow fronts meet and rejoin during the injection molding process.
Welding Lines Explained: Production and Solutions
网页2023年8月19日 · The welding line, also referred to as the fusion line or bonding line, is formed when the cooled molten resin from the leading edge fails to fuse completely at the joint, resulting in a visible line. This phenomenon is commonly observed at the point where two streams meet, or where one stream converges after bypassing certain geometric shapes ...
Understanding Injection Molding Weld Lines: Causes, Effects, and ...
网页2023年6月9日 · The injection molding weld line, also known as a knit line, is a visible line or mark that occurs in an injection-molded part where two or more melt fronts meet and fuse together during the molding process. It happens when the molten plastic material flows around obstacles, such as inserts or cores, and rejoins on the other side.
Weld Line in Injection Molding: Causes and Solutions
网页Weld line, also known as knit line or meld line, is a visible line or mark on the surface of a plastic part where two or more flow fronts of molten plastic meet and fuse together. Weld line can affect the appearance, strength, and functionality of injection molded parts.
Weld‐lines and its strength evaluation in injection molded parts: A ...
网页2023年8月31日 · Weld-line is a defect that arises in injection molding when two or more flow fronts collide. The weld-lines are undesirable from both aesthetic and functional points of view and their effect is different for varied materials, process conditions, loadings, forms of weld-line, etc.
