What is the two stage extruder used for?

Publish Time: 2021-11-01     Origin: Site

The two-stage extruder is composed of two single-screw extruders or is composed of a twin-screw extruder and a single-screw extruder. the primary stage screw of the two-stage extruder encompasses a larger diameter, a deeper screw groove, and a bigger heating power. primarily for conveyance and plasticizing materials. The second-stage screw encompasses a smaller diameter and a shallower groove. The heating power is smaller than that of the first stage, however, the quantity of revolutions is on top of that of the first stage. it's primarily to advance the plasticization of the materials sent from the primary stage and complete the extrusion molding of the homogenization well. Then, let's introduce well what's the 2 stage extruder used for?


Here is that the content list:

Thermometer automatic adjustment

The two-stage extruder transmission box is advanced in style and compact in structure, which realizes the characteristics of high speed, high output, high torsion, and stable operation. The barrel of the two-stage extruder adopts bimetal sleeve wear-resistant alloy with high hardness. The screw of the two-stage extruder adopts high-speed alloy steel, which will increase the wear and tear resistance and prolongs the service life.

Two-stage extruder temperature management meter realizes automatic management, every temperature zone is controlled accurately, the action is sensitive, display, and therefore the degree of automation is high. The machine head is provided with a soft temperature measurement thermometer and pressure sensing element, that is additionally appropriate for varied materials. method needs for process.

Tracking detection

Two-stage extruder start-up temperature interlock; operating pressure protection and interlock; synchronous management of the transmission magnitude relation of the 2 major elements of extrusion and traction; synchronous management of take-up and traction; on-line detection and feedback management of outer diameter; in step with varied the one machine and therefore the whole machine chase management of various elements area unit needed. Through the detected gauge reading, you'll recognize the pressure state of the plastic throughout extrusion, and usually take the thrust limit worth and alarm management.  Two-stage extruder is widely used in plastic material processing.

Suitable for different materials

Different two-stage extruders have completely different uses. Pipe extrusion: appropriate for PP-R pipes, letter of the alphabet gas pipes, PEX cross-linked pipes, aluminum-plastic composite pipes, ABS pipes, PVC pipes, HDPE chemical element core pipes, and varied co-extruded composite pipes.Sheet and sheet extrusion: appropriate for the extrusion of PVC, PET, PS, PP, laptop, and alternative profiles and sheets. Extrusion of assorted alternative plastics like silk, rods, etc.Extrusion of profiles: Adjusting the speed of the extruder and ever-changing the structure of the extruder screw is appropriate for the assembly of assorted plastic profiles like PVC and polyolefins. changed granulation: it's appropriate for mixing, modifying, and enhancing granulation of assorted plastics.

The two-stage extruder depends on the pressure and cut force generated by the screw rotation to form the fabric totally plasticized and equally mixed, forming through the mouth die.

Nanjing Haisi Extrusion Equipment Co., Ltd. could be a sophisticated company, that consists of a well-experienced team in R & D style, producing technique, sales service, and bases on extruder trade for several years.
