The Basic Working Principle of the Extruder process, Extruder is a plastic processing equipment, it through the plastic parts or powder Heating and Melting, through the rotation of the Screw to melt the Molten plastic is Extruder Cylinder Mold to form the required Cross - section shape (le principe de travail de base du processus extruder, Extruder est un équipement de processus plastique, il est à travers les parties plastiques ou la santé et le melting, à travers la rotation de l'écran pour Melt la plastique molle est Extruder Cylinder Mold to form the required Cross - section Shape Le principe de travail de base du processus Extruder peut être divisé dans les étapes suivantes:

Alimentation: put Plastic articles or powder into the Extruder Feed port

Plasticizing and Mixing: in the feed Area, the Screw Heats and squeezes the Plastic by rotation, Transforming the Solid Plastic into a Molten State and thoroughly Mixing it with additives.

Extrusion: the Molten Plastic enters the Extrusion Area of the barrel, and under the Action of the Screw, the Mold inside the Extruder Barrel forms the required Cross - section shape (en anglais seulement)

Cooling and Curing: after the Extrusion is passed through the Mold, it’s Cooled in a Cooling Tank and gradually Solidified into a plastic product of the DESIRED SHAPE (après l’extrusion est passée à travers le moule, il est coolé dans un tank de Cooling et de graduation solidifié dans un produit plastique du shape désiré).

Cutting and winding: The extrudates are cut to the required Length by the Cutting DEVICE, and the products are Rolled or Stacked by the winding device.

Types et zones d'application des extrudeurs plastiques

According to different Extruder Cylinder Structure and use, plastic Extruder can be divided into Single Screw extruder, Twin Screw Extruder and Solid Extruder (en anglais seulement).

Single Screw Extruder

Single Screw Extruder is the most widely used extruder, suitable for the Production of various Plastic Products, such as plastic film, pipe, plate and so on.

Twin Screw Extruder

Twin - screw extruders are composed of two Screws rotating in the same or oppositive direction, with Higher Extrusion Capacity and Better Plasticizing effect, suitable for the Production of High - speed extrusion, high viscosity and difficult to handle plastic materials.

Solid Extruder

Solid Extruder is suitable for the Production of Small Diameter Plastic Products, such as a small pipe, Wire and Cable Sleeve (en anglais seulement)

Common Problems and Solutions in the Process of Plastic Extruder (en anglais seulement)

In the Process of Plastic extruder, Some Problems are often encountered, such as Unstable Extrusion Speed and High Extrusion temperature (en anglais seulement) Voici quelques problèmes et solutions communs:

La vitesse d'extrusion est invisible

Possible causes include: Uneven Screw Accommodation, Screw Wear, barrel and Screw clearance is too large. Solutions include: nettoyage de l'écran, correction de l'écran, replacement des parties du monde.

Le temps extrême est too high

Possible causes include: the plastic Material Temperature is too high, insufficient Cooling, cylinder and Screw Friction is too large (le temps plastique est élevé, instructeur Cooling, cylindre et Screw friction est large). The solution includes: réduire le temps matériel, Strengthening Cooling, Lubricating the Cylinder and Screw.

Le sum up

The Plastic Extruder is an important plastic processing equipment, which realizes the Extrusion of Plastic Products by Heating and Melting Plastic and Rotating the Screw (l'extrudeur plastique est un équipement de traitement plastique importé, qui est réel, l'extrusion des produits plastiques par la santé et le melting et la rotation de l'écran). According to different Extruder Cylinder Structure and use, plastic Extruder can be divided into Single Screw extruder, Twin Screw Extruder and Solid Extruder (en anglais seulement). In the Extrusion Process, the Problems of Unstable Extrusion Speed and High Extrusion Temperature may be encountered, but these problems can be effective solved through coresponding solutions (en anglais seulement).
