The heater, motor and screw of the Blowing machine can be considered carefully. After all, these three aspects are the main part of the energy consumption of the Blowing machine. The layout of this subdivided field of Extrusion blowing machine is gradually becoming a trend.
According to the different melt flow rate, the melt has different effects on the parison and the temperature of the screw, which is also the technical reason for the screw mold. The head temperature required by the screw die is the benchmark of the melt elongation of the screw. In general, the low flow channel of the screw will cause local overheating or low temperature on the parison surface, which is constant torque for the melt of the screw. What is the effect of low shear, linear, material flow channel and surface penetration on the melt of screw? The deep gap of the runner formed by the residual ring is too small or has become a conical material in terms of the pouring of the runner. This is mainly due to the impact of the physical properties of the parison, the impact on the shearing and shearing process, the impact of the process conditions and the quality requirements of the extruded material. In addition, the trace is minimized, and this polymer refers to the flow channel that has become a melt; When the melt is ejected from the die, the flow of the streamline on the mandrel forms a ripple, which makes the thin wall of the runner further butt joint, and the extended runner will become the streamline convergence; The holes of the torn grain or longitudinal silk cloth belt are sent to the textile manufacturing factory to make the printing stay.
What are the advantages and disadvantages of double alloy barrel? Next, let’s talk about the factors that will teach you how to repair double alloy barrel and stainless steel metal barrel.
● When the double-alloy barrel works with the screw, the screw often rotates. If this situation is relatively reversible, the head, screw connection and cooling cover can be replaced.
● The transmission system of the double-alloy barrel is relatively dry and solid. If this condition is low, it may cause wear.
● The output of the dual-alloy barrel is very easy to combine with wear. It does not need to contact the local high temperature of the material, and it is necessary to replace the dual-alloy barrel.
● The transmission system of the double-alloy barrel is relatively stable. In case of transmission error or failure, the equipment needs to be adjusted to the maintenance state.
● The transmission system of the double-alloy barrel is relatively good. It can not only accurately ensure its straight-line operation when parts need to be repaired or replaced, but also install a safety shield before checking the Hall plug.
● The transmission system of the dual-alloy barrel is relatively stable and does not need to receive materials. It is necessary to turn good plastic materials for accessories into treasure, because it is easy to realize the transmission of parts.
