The Automatic Dosing & Weighing System provides an accurate solution for PVC raw material preparation before mixing and extrusion processing. The system automatically measures, doses, and transfers PVC resin, calcium carbonate, stabilizers, lubricants, pigments, and other additives according to preset formulas.
The PVC Raw Material Dosing System helps manufacturers improve production efficiency and maintain stable material quality. The automatic weighing process controls each material quantity precisely and reduces errors caused by manual operation.
The system uses storage hoppers, feeding units, weighing sensors, and PLC control technology. Operators can select different formulas through the touch screen, and the equipment completes the feeding and weighing process automatically.
During operation, raw materials enter the weighing unit through screw conveyors or other feeding systems. The weighing sensors monitor the material quantity in real time. When the target weight is reached, the system stops feeding automatically.
After weighing, the prepared materials transfer to the PVC mixing system, storage equipment, or extrusion line. This automatic batching process improves production efficiency and provides stable material supply for continuous production.
The Automatic Dosing & Weighing System is widely used in SPC flooring production, PVC pipe manufacturing, PVC profile extrusion, WPC production, plastic sheets, and other plastic processing industries. The system can handle PVC powder, fillers, additives, and plastic granules for different production requirements.
The equipment can connect with PVC hot and cold mixing machines, vacuum conveying systems, storage silos, screw conveyors, and extrusion lines. This complete material handling solution helps manufacturers create an automatic raw material preparation process.
With high weighing accuracy, flexible configuration options, and customized design, the Automatic Dosing & Weighing System provides a reliable solution for modern PVC and plastic production.
1. What is the purpose of the Automatic Dosing & Weighing System?
The Automatic Dosing & Weighing System is designed to automatically measure, dose, and transfer PVC raw materials, fillers, additives, and plastic compounds according to preset formulas. It provides accurate material preparation before mixing and extrusion processing.
2. What materials can the dosing and weighing system handle?
The system can handle different types of raw materials, including PVC resin powder, calcium carbonate, stabilizers, lubricants, pigments, additives, and other plastic processing materials.
3. What is the production capacity of the Automatic Dosing & Weighing System?
The production capacity depends on the system configuration and factory requirements. Standard models can provide capacities from 500kg/h to 8000kg/h, suitable for medium and large-scale plastic production lines.
4. How accurate is the weighing process?
The system uses high-precision weighing sensors and automatic control technology. The standard weighing accuracy can reach ±0.1–0.2%, helping manufacturers maintain stable material ratios during continuous production.
5. How does the automatic dosing process work?
The system stores different materials in separate hoppers. According to the selected formula, each material is automatically fed into the weighing unit. After reaching the preset weight, the system transfers the prepared materials to mixers or production equipment.
