Plastic Molding defects
Common Defects in plastic injection Molding Read this to know about common defects related to plastic injection molding process. Futech machines helps you in a best way to resolve all of these defects
Injection molding is a widely used manufacturing process that produces plastic parts in various shapes and sizes. As effective as it is, various defects can occur during injection molding. Some of the most common plastic injection molding defects are:
- Flash: Flashing occurs when excess material is forced out of the mold during the injection molding process, causing a thin layer of plastic to form around the edges of the room.
- Short shot: A short can occur when the mold is not completely filled, resulting in an incomplete part or missing elements.
- Sink Marks: Sink marking occurs when the plastic cools and shrinks unevenly, creating indentations or indentations in the surface of the part.
- Warpage : Warping occurs when plastic cools and shrinks unevenly, causing parts to warp or bend.
- Burn Marks: Burn marks can occur when plastics are overheated or burned, leaving dark or discolored marks on the surface of the part.
- Weld line: A weld line occurs when two or more plastic flow fronts meet and form a visible line on the surface of the part.
- Brittleness : Brittleness occurs when the plastic becomes too brittle and breaks easily, making it difficult to use the part for its intended purpose.
- Void: Void is the presence of air pockets or bubbles inside the plastic during the injection molding process, making the part weak or having a hollow cross-section.
- Flow marks: Flow marks appear when the plastic flows unevenly through the mold.
