Warpage deformation is when the shape of the injection molded product is different from the shape of the mold cavity. It\u2019s one of the common defects in plastic products. There are many reasons for warpage deformation, and just using process parameters to solve it is usually not enough. This article will talk about the causes of warpage in injection molding and how to solve them.<\/p>\n

When you make plastic parts with injection molding, you have to fill the mold with melted plastic. Then the plastic cools and turns solid inside the mold. This is a very important part of injection molding. The temperature, pressure, and how fast the plastic flows all affect how good the parts are and how fast you can make them. When the pressure is high and the plastic flows fast, the plastic gets stretched out in the direction the plastic is flowing. It also gets stretched out in the direction that is not the flow direction. This is called the \u201cfrozen effect.\u201d The \u201cfrozen effect\u201d makes the plastic parts have stress inside them. The temperature also makes the plastic parts bend.<\/p>\n
