Extrusion unit is plasticization section of the PVC formulation with a suitable extruder. PVC formula in the extruder is plasticized at required temperatures and under high pressure. Plate pattern is very important in this process, because it provides transition between the complement of the extruder and calendering.
EXTRUSION UNIT FEATURES
- Extrusion unit control panel stores and adjusts both the extruder and the plate mold process data, as well as a stable control without fluctuation in the production process.
- If a stable product is not supplied, this situation will have thick carvings, surface degradation, color changes and unwanted pauses in production.
- Heat control is very important during the extrusion process. In the system where heat control cannot be provided, edge band deformations occur.
- Degassed PVC formula, which has completed the plasticization phase in the extruder, spreads to the sheet form and becomes a film form.
EXTRUSION PROCESS PARAMETERS
Errors in the following parameters causes major problems in the design and use of the edge band. In order to avoid these problems, all machinery and equipment must complete each other correctly.
