Structure and working principle: Vertical injection molding machine: The injection device and the clamping device are on the same vertical center line, and the mold opens and closes in the vertical direction. This design occupies a small area and is suitable for occasions with limited space.Horizontal injection molding machine: The injection device and the clamping …

The differences between vertical injection molding machines and horizontal injection molding machines are mainly reflected in the following aspects: Read More »

As the plastic flows through the injection molding machine and different parts of the mold, there is a loss of pressure on the plastic flow front due to drag and friction. In addition, as the plastic contacts the mold wall, it begins to cool, increasing the viscosity of the plastic and requiring additional pressure to …

1) Viscosity curve The purpose of making a viscosity curve is to select a suitable injection speed injection molding process . When there are slight fluctuations in various parameters, it will not cause a large change in melt viscosity. The fluctuation between each mold should be as small as possible to ensure the repeatability of …

Two-color injection molding technology is also called double-material injection molding technology. This is a technology that uses two plastic materials to be mixed and injection molded to form plastic products. Its technical connotation is actually to use a mold component to shape the shape and mold it in the mold. Welding work, so the basic …
