Product introduction

Price of high-quality extruder screw If there is a wear zone on the screw and barrel, then the screw cannot effectively transport the material forward. If the equipment is suspected of being worn, the screw and barrel should be inspected and the clearance between the two should be checked. If the clearance between the screw and barrel exceeds the standard value, replacement or repair work should be started.

Detailed introduction

Price classification of high-quality extruder screw :

1. PC special screw: For PC and other high-viscosity plastics, it has low shear heat generation, acid corrosion resistance, medium and small diameters, forming PC, PP-R, flame retardant ABS, etc. It can also form general plastics and PMMA ordinary products. The color mixing effect is poor. If plastic powder is added, a reinforced color mixing screw needs to be customized.

2. PA special screw: Aiming at the characteristics of low PA viscosity, difficult coloring, fast melting speed and good self-lubrication, the screw has good color mixing effect, stable feed volume and good exhaust effect. Middle diameter. Molding of PA, PP, LCP and other crystalline low-viscosity bottom plastics is effective. Can also be molded into general plastic. It is not suitable for plastics with high viscosity and poor thermal stability such as PC and PMMA flame retardant ABS (the middle temperature is too high and decomposes).

3. PMMA special screw: According to the requirements of PMMA transparent products, good plasticizing effect, low decomposition rate and other characteristics, good plasticization, low shear heating and good color mixing. Middle diameter molding PMMA, PP-R, PC, ABS, etc. has a good effect when adding color powder, such as plastic with flame retardant, screws need to be chrome-plated.

4, UPVC special screw: for UPVC high viscosity, easy to decompose, strong corrosive and PVC pipe joints require good plasticization and other characteristics. The screw has good plasticization, less shear heat, and acid corrosion resistance. Because there is no apron, it cannot be used for low-viscosity plastics and products with more accurate injection speed and pressure classification. In addition, due to the need to dissipate heat and cool down, when making UPVC products, the barrel (melt tube) must be used in conjunction with the screw with forced air cooling.

5. PET special screw: For the characteristics of low PET viscosity, large specific heat capacity, easy to stick materials and PET preforms, the characteristics of fast plasticization and uniform plasticization are required. The preform yield is high when the preform is blown. Large diameter can also be molded into general plastic.

6. PBT special screw: Aiming at the characteristics of PBT that is easy to decompose, sensitive to pressure and the need to add glass fiber, the screw generates stable pressure, and uses dual alloys to improve wear resistance.

7. Acid screw components: For the strong corrosive characteristics of CP, CA and other acidic plastics, the screw, melter barrel and other plasticized parts are specially designed in terms of structure and surface treatment. The screw assembly has good corrosion resistance.

Price range of high-quality extruder screw : blending modification (rubber blending, plastic alloy), homogeneity, plasticization, filling modification, granulation. Engineering polymer and glass fiber (carbon fiber) reinforcement. Masterbatch, functional masterbatch. Masterbatch. Special materials, powder coatings, oil pipeline coating materials. Reactive extrusion. All kinds of cable materials. Exhaust after-treatment.
