• The influence of the length of the screw of the injection molding machine on the injection range

    The influence of the length of the screw of the injection molding machine on the injection range

    The length of the screw is generally not measured in absolute length, but in length relative to the diameter. In this way, screws of different diameters can also be compared in length. This length is called the aspect ratio, represented by L/D. The length of the screw is of course only the part with... read more

  • Cooling method of extruder screw when working

    Cooling method of extruder screw when working

    The screw needs to be cooled when extruding the material, mainly to ensure the smooth progress of the production and prevent the material from decomposing due to the excessively high plasticizing temperature. For example, cooling in the feeding section of the screw is to prevent the temperature of t... read more

  • The effect of corrosion on the screw barrel of injection molding machine

    The effect of corrosion on the screw barrel of injection molding machine

    Strictly speaking, corrosion and wear are two completely different phenomena. The prerequisite for wear is the existence of forceful action and relative motion. Corrosion is just a chemical reaction. Even if the screw does not rotate, the melt will cause corrosive damage to the surface of the screw.... read more

  • Why does the screw of the injection molding machine slip?

    Why does the screw of the injection molding machine slip?

    For hygroscopic materials (such as nylon), the high water content of the resin can also cause the screw to slip. Improper drying will be significantly lower The viscosity of the material and the generation of water vapor in the barrel will reduce the conveying power of the screw. In fact, there are ... read more

  • How to set the low pressure and high pressure clamping position of the injection molding machine

    How to set the low pressure and high pressure clamping position of the injection molding machine

    The clamping process is usually divided into three/four stages, roughly fast/slow-low pressure-high pressure; Quick clamping, according to the structure of the mold, it is flat, or there is a slider. Different molds first set the pressure/speed/position during rapid clamping, and set the appropriate... read more
