The 32D twin-screw technology reaches benchmarks in PVC sheet production with its process concept
For manufacturing high-quality, premium PVC sheets, above all, an excellent melt homogeneity is required. This is achieved in the 32D twin-screw extruder of the sheet series by two measures and continuously ensured through optimized screw geometry and an exact temperature control in the process unit. The screws are, by default, molybdenum welded, chrome-plated across their entire length and externally heat-balanced. This guarantees an optimum process control and melt liquid control. An optimum vacuum unit with double-solid separator provides for uniform vacuum. The system is easy to clean and was conceived to be very user-friendly. While the barrels of the KMD 90-32/PL, the KMD 114-32/PL and KMD 133-32/PL are cooled via aluminum half-shells with air, the barrel is cooled in the KMD 164-32/PL and the KMD 184-32/PL via aluminum half-shells with oil.
The 32D sheet technology stands for highly efficient sheet production: Investing in 32D sheet technology pays off quickly.
