The single screw is generally divided into three sections in the effective length. The effective length of the three sections is determined according to the diameter of the screw and the pitch of the
The twin-screw extruder performs all of the above processes through a barrel with a screw and a spiral. The plastic pellets enter the barrel through the hopper at one end of the barrel and are then p
The barrel is increased in diameter due to wear. If there is a certain nitriding layer, the inner hole of the barrel can be directly grinded to obtain a new diameter size, and then a new screw is prep
Extrusion molding is a process in which a compound having a certain plasticity is continuously pressed out through a mouth shape under certain conditions to make it a product having a certain section
The temperature control system of the domestic low-end screw extruder generally adopts the separation instrument control scheme, and the heating mode is the district heating of the electric heating c
Many of the plastic products we see in our daily life are extruded by plastic extruders, such as some door and window seals, plastic tubes, plastic threading tubes and plastic wires.
The temperature of the tube blank extruded from the machine head is high, the plastic extruder is still in a dissolved state, and the shape cannot be fixed. Therefore, the material needs to be cooled
The extruder is a screw extruder, which relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and uniformly mixed, and formed by
The mud is too dry. At this time, the dry mud should be taken out first. It is best to remove the machine mouth and the machine head, start the dry material in the machine draining mud tank, then inst
The small extruder has the advantages of high output, high quality, high speed and high torque. It is mainly used for extrusion, granulation and rolling of wood-plastic materials, uniform plasticizat
Whether the current of the main motor is stable. If the fluctuation is large or rapid, the supply amount should be temporarily reduced. After the main current is stabilized, it will gradually increase
