Piv txwv li, rigid PVC has high viscosity and requires strong shear force for plasticization, so a conical twin-screw extruder (HTE series) is preferred; flexible PVC has good fluidity and low viscosity, so a single-screw extruder (ZTE MODEL) or a parallel twin-screw extruder can be selected.
2.3.2 Muaj Peev Xwm Ntau Lawm:
Customers need to select the extruder with appropriate production capacity according to their own production scale and market demand. If the production demand is small (less than 100kg/h), the ZTE MODEL extruder is suitable; if the production demand is large (more than 100kg/h), the HTE series extruder is more suitable.
2.3.3 Product Quality Requirements:
If the customer’s products have strict requirements on performance (xws li cuam tshuam tsis kam, transparency, nplaim retardancy), the HTE series extruder with high plasticization efficiency and uniform mixing effect should be selected; if the product quality requirements are general, the ZTE MODEL extruder with stable performance and high cost performance can be selected.
2.3.4 Energy Consumption and Maintenance Cost:
Energy consumption and maintenance cost are important factors affecting the long-term production cost of customers. The HTE series extruder has the advantage of low energy consumption per unit product, but the initial investment is relatively high; the ZTE MODEL extruder has a lower initial investment and maintenance cost, which is suitable for customers with limited budget.
2.3.5 Compatibility with Auxiliary Equipment:
The selected extruder should be compatible with the existing auxiliary equipment (such as mixers, cov pelletizers, and conveyors) to form a complete production line, avoiding the problem of equipment mismatch affecting production efficiency.
Our professional technical team can provide one-stop consulting and selection services for customers. According to the customer’s specific needs, we will recommend the most suitable extruder model and provide customized equipment configuration and process design to help customers achieve the best production effect with the most reasonable cost.
