PE foam film extrusion screen changer

Impurity Filtration PE raw materials may be mixed with impurities such as dust, metal shavings, gel particles, etc. during the production process. The screen changer intercepts these impurities through the screen and prevents them from entering the downstream equipment (e.g., molds, melt pumps), thus reducing defects such as surface imperfections, bubbles, and holes in the products. For example, in the production of XPS foam sheet, the screen changer can reduce the content of impurities to less

Structure and performance of PVC hydraulic screen changer

PVC hydraulic screen changer adopts straight-through runner design, no dead corners, no material hiding, more suitable for PVC and other high-viscosity materials, can ensure smooth material flow, reduce the time of material retention in the runner, reduce the risk of material degradation. PVC hydraulic net changer its structure is relatively simple, the whole is more compact, occupies a small space, easy to install and maintain, can be used with different specifications of the PVC production equ

Extruder Screen Changer Installation Guide

1. DISASSEMBLY OF THE DIE First of all, we have to disassemble the die. Remember to preheat the enamel where the extruder and the die are connected, and wait until the temperature is right before stopping the machine to dismantle it. Otherwise, the material in the runner will solidify and cant be disassembled. Safety first, prevent the mold from falling and hitting your feet. Remove all the bolts from the enamel. 2. Panning the mold or the main unit Next, we have to pan the mold or the main unit

Do rubber extrusion lines need to use screen changers?
