We will also introduce examples of issues where black resin remains on the product terminal during the color change from black to beige!
Hot runners eliminate the need for unnecessary runners during molding because the gates are always molten. However, this means that material remains in the runner at all times. If you try to mold a different color resin using the same hot runner, what happens is that if the previously molded material was black, switching to beige will still leave black resin behind, resulting in defective products. To resolve this issue, it is necessary to discard 20 to 30 molded products, which poses significant challenges in terms of both environmental impact and cost. Therefore, we began the development of the Twin Way Valve Gate (TWVG), which can switch between two different types of materials in one go. *For more details, please refer to the related links or feel free to contact us.*
