PVC tube injection molding machine parameter

For the customized PVC tube injection molding machine, the screw is a vital part, and its performance determines the quality and efficiency of the processed products. Next, let's talk about the screw of our PVC tube injection molding machine.

First, we need to understand the characteristics of PVC Plastics:

1. No obvious melting point, softening at 60 ℃, viscoelastic state at 100 ℃ - 150 ℃, narrow melting temperature range at 140 ℃, poor thermal stability, easy decomposition, rapid decomposition at 170 ℃, softening point close to decomposition point, decomposition and release HC1 gas.

2. Due to the high viscosity of PVC melt, poor thermal stability, temperature and time will lead to decomposition, it has a corrosive effect on general steel, that is, the material will corrode the machine.

Understand the characteristics of PVC material. The design of plasticizing screw and barrel of our PVC tube injection molding machine is a special grade of PVC.

1. Integrated screw design, low shear to prevent overheating. The flow channel must be smooth without dead corners to prevent material accumulation and decomposition

2. Anti corrosion treatment of screw barrel

3. Hard chromium plating on screw

4. The screw barrel of the large machine is equipped with oil cooling and water cooling systems

5. Segmented barrel shield design, separate blower heat dissipation, more accurate barrel temperature control
