Who knows about the temperature regulation method of extruder?

Summary. Hello dear! The extruder is divided into several temperature zones according to different models, generally divided into barrel temperature zone, head temperature zone, barrel temperature zone is divided into several temperature zones according to different stages, most of them are automatic temperature control instruments, when the temperature is lower than the set value, the electric heating ring will automatically cut off the power after the heating reaches the set value, and after the shear heat is overheated, air cooling or water cooling is adopted.

The screw extruder relies on the pressure and shear force generated by the rotation of the screw, which can make the material fully plasticized and evenly mixed, and formed through the die. Plastic extruders also belong to one of the categories of plastic machinery. According to the direction of material flow and the angle of the screw centerline, the extruder can be divided into right-angle head and beveled head.

The shell of the machine head is generally fixed on the fuselage with bolts, the mold inside the machine head contains the mold core base, and then it is fixed on the inlet port of the machine head with a nut, the inside of the mold core seat is also equipped with the mold core, and the center of the mold core and the mold core seat have holes, and its function is used to pass through the core. According to the different types of pressurization methods, the extrusion process can be divided into two types: continuous extrusion and intermittent extrusion. The equipment used in the former is a screw extruder, and the equipment in the latter is a plunger extruder.

In this case, screw extruders can be roughly classified into single-screw extruders and multi-screw extruders based on the number of screws. Hope it helps!

Plastic extruders also belong to one of the categories of plastic machinery. According to the direction of the material flow of the machine head and the angle of the screw centerline, the extruder can be divided into a right-angle head and an oblique head. The shell of the machine head is generally fixed on the fuselage with bolts, the mold inside the machine head contains the mold core base, and then it is fixed on the inlet port of the machine head with a nut, the inside of the mold core seat is also equipped with the mold core, and the center of the mold core and the mold core seat have holes, and its function is used to pass through the core.

The electromagnetic heating of the plastic extruder can be increased to a maximum of multiple degrees.

Hello dear! The heating temperature of ABS plastic extruder is generally 100-150 degrees Celsius, I hope it can help you!

1) Air-to-mold: Adjust the mold before production, adjust the distance or gap between the mold core and the mold sleeve evenly with the naked eye, and then tighten the mold matching screws.

2) Running glue to the mold: after the plastic plasticization is good, adjust the mold screws, according to the number of the circumferential direction of the mold mouth, one side of the glue, one side of the adjustment, the adjustment should first loosen the thin screw, and then tighten the thick screw; At the same time, take samples to check whether the thickness of the plastic ant is eccentric, until it is evenly adjusted, and then tighten the die screws respectively.

3) Wire matching: suitable for small cross-section wire and cable mold adjustment. The wire is passed through the mold core, connected with the traction wire, and then the glue is run for fine-tuning.

After the glue is run, adjust the screw and traction speed, start the car and route the sampling hall, and then stop, observe whether the thickness of the plastic layer of the sample is uniform, repeat several times until the adjustment is uniform, and then tighten the screw.

4) Lighting mold: suitable for polyethylene plastic wires and cables. Use the light to irradiate the insulation layer and the sheath layer, observe the thickness of the upper, lower, left and right sides, adjust the die alignment screws until they are evenly adjusted, and then tighten the screws.

5) Sensory modulus: It is an empirical method of modularity. Feel the thickness of the plastic layer by touching it and adjust the mold. It is suitable for the outer sheath of large cross-section wires and cables.
