Gravimetric Control System
Description
Performance & Advantages

Quality Control & Cost Cut
- Precise meter-weight control can cut raw material consumption by 2–5%, with the economic benefit being especially pronounced on large-diameter pipe extrusion lines.
- The system automatically compensates for production variables such as voltage fluctuations and changes in melt flow, ensuring uniform wall thickness, stable ring stiffness, and a significant improvement in the product pass rate.

Integrated Control
- The gravimetric control system will display the total energy consumption of the equipment and energy consumption per ton of product, helping you identify the most cost-effective operating conditions.
- The gravimetric control system will automatically raise an alarm if the line runs short of material or the motor becomes overloaded, keeping production safe.

Multi-layer Co-extrusion
- For 2-, 3-, and 5-layer co-extrusion pipe lines, Jwell supplies multiple meter- gravimetric control system - one for each layer - so you can independently regulate the extrusion output and meter weight of every individual layer. This keeps the layer thickness ratios precise and product performance consistent.

FAQ
Q: 1. How much material can be saved?
A: 1. The actual saving depends on product type and process stability. Many pipe manufacturers achieve measurable reductions in raw material consumption through accurate meter-weight control.
Q: 2. Can the system be installed on existing extrusion lines?
A: 2. Yes. The gravimetric control system can often be retrofitted to existing pipe extrusion lines.
Q: 3. Is it suitable for HDPE, PVC and PPR pipes?
A: 3. Yes. The system is compatible with various thermoplastic pipe production processes.
Q: 4. Can it control multilayer pipe production?
A: 4. Yes. Independent control is available for each extrusion layer.
Q: 5. How does your factory do regarding quality control?
A: 5. We have passed the IS09001:2015 Quality Management System and CE certificate and we have a special QC department in charge of products' quality. If you also need other certificates, we also can help to apply.
Q: 6. How is ROI calculated?
A: 6. ROI is typically based on raw material savings, reduced scrap, and improved production consistency.
