Something You Need Notice When Renewing Items of Extruder

It is very convenient to open twin screw extruder for checking abrasion level of elements and barrel inter-sheet, which achieves to change and repair items effectively and this avoids unnecessary consumption. If electric stoppage happens and the extruder stops heating, it need to re-heat and maintain the temperature before opening the extruder when electricity recovering. Related to the heating process, we often heat the heating zone individually. When zone reach the temperature point, however, the die head does not reach the temperature( die head has thicker steel coating and larger…

Filler Masterbatch Advantage and Disadvantages

So-called plastic masterbatch for easy operation, is the granules or powder fiiled and mixed with resin. Main content of filling masterbatch is the filler, which is mainly applied for PP or PE processing and we also called it PP or PE filling masterbatch. Advantage Firstly, manufacturers choose filling masterbatch for cutting cost. Secondly, filling masterbatch can decrease shrinkage ration. For example, since large shrinkage ration performed by PP, dent may appear on the surface of product when producing good with high thickness, which influences the appearance of product. Thirdly, filling…

Knowledge of Screw & Barrel

Extruder screw and barrel is the most important component of Twin Screw Extruder. It directly decided the lifetime of extruder. The screw and barrel of twin screw extruder adopt segmented design. Different combination of barrel decide the extruder L/D; different combination of screw decide the extruder function. Extruder Barrel: Extruder barrel is made with bushing and cylinder, bimetallic treatment. Bushing is made of α101, cylinder is made of #45 steel matrix. Extruder Screw: Extruder screw is composed of shaft and screw elements.Shaft is made of 40CrNiMoA, elements is made of  W6Mo5Cr4V2. Screw elements include conveying unit,…
