A knit line is formed when two or more plastic flows collide and solidify or knit together in the middle of a part during the injection molding process.

Present no problem at all, be a cosmetic issue, or cause a potentially serious structural problem. It happens when the molten plastic material flows around obstacles, such as inserts or cores, and rejoins on the other side.

When these areas are visible, it can pose no problem at all to the piece, be nothing more than a cosmetic flaw, or can be a source of major structural problems for your piece. They appear around holes or seams of an injection molded part, and some may call them “flow lines” or “weld lines”. Web a knit line is any line, visible or not, where two resin flows meet.
