Product Introduction:

Usually, two or more hot gates are required to fill. For a regular hot pouring system, the gate opens simultaneously at the beginning of injection. This glue feeding method inevitably has fusion defects, that is, when the two molten materials converge at the front, fusion marks are formed due to the incomplete fusion of the two molten materials, which react on the surface of the product, which is commonly known as fusion marks. Although improvements can be made by increasing the melt temperature, increasing the holding pressure, and adjusting the injection molding process parameters, the actual improvement effect is limited.
