The case we'd like to share is on how to achieve "speed-up and cost-saving" in the production of PVC drainage pipes. LIANSU helped customers to increase production capacity from 800kg/h to 1240kg/h by optimizing old equipment with capacity increase of more than 56%.



Transformation Solution

1. Optimized design of Screw and Barrel

The optimized screw and barrel design enhanced shearing and mixing capabilities, significantly improving plasticizing efficiency and ensuring sufficient material melting even at high production.

2. Accurate and stable material dosing & feeding

Loss-in-weight feeder offers excellent performance in preventing material bridging and flushing. Even with materials with poor flow ability, it can utilize precise PID algorithm to achieve accurate automatic control of the loss-in-weight process, ensuring production stability and improving product quality while saving about 2% of raw materials.

3. Online Automatic Pipe Weighing

Pipe Weighing stacker measures the weight of qualified pipes and acts as a real-time quality inspector, recording the actual weight of each pipe in PC database.

4. Intelligent Production Data Manage

Production management data is collected and uploaded in real time. Managers can remotely view production output, energy consumption, and equipment operating status via mobile app with multi-dimensional report analysis, which helps to achieve lean management.
