The injection hole of the mold is used to resist the nozzle during pre-molding to prevent the melt from flowing out of the nozzle when the back pressure is high. After pre-molding, it can prevent the nozzle and the mold ...
The deflection angle of the thread fit and the softer characteristics of stainless steel are easy to cause locking The fit between the screw and the nut is a clearance fit, which has its own implementation of the interna...
Why It's Crucial to Manage Melt-Temperature in a Twin-Screw Compounding Extruder Managing and controlling melt temperature and degradation in a corotating compounding twin is critical to achieve process optimization. For...
It is very difficult to estimate the life expectancy of a screw or barrel. Due to many variables effecting productivity, each barrel and screw is unique. However, the primary cause of premature deterioration is excess we...
Generally speaking the ratio of importance in the selection between the screw and barrel should fall more so on the screw and non-return design/selection and metallurgy. So if you are still keeping score, the need to sel...
The barrel nuts come with a zinc plating to prevent rust. Sometimes this coating builds up inside the threads at the plating facility. Before trying to install fasteners in your bench, thread the bolts fully in and out o...
