1.High-efficiency extrusion molding: The extrusion system achieves stable material conveying and heating plasticization, ensuring the parison is extruded continuously and evenly, and can perfectly meet the molding demands of solar tank liners in various specifications.
2.Accurate wall thickness regulation: Fitted with a MOOG-type parison thickness adjustment system, it enables precise calibration of parison wall thickness at each position based on the liner’s structural design and stress bearing requirements, effectively preventing local under-thickness or over-thickness issues and enhancing both product quality and service life.
3.Stable mold clamping and injection: The accumulator injection system is synergistically matched with the mold clamping system, and the clamping force is tailored to the specifications of different machines. This ensures tight mold closure during liner forming, precise injection volume control, and consistent dimensional accuracy of finished products.
4.Intelligent temperature control and cooling: Multi-stage temperature regulation of the die head optimizes the plasticizing effect of raw materials; the dedicated cooling system rapidly cools the formed liners, which shortens the production cycle and boosts overall production efficiency significantly.
5.Real-time fault and status monitoring: The PLC control system conducts real-time monitoring of all equipment operating parameters. In the event of a fault, it triggers timely alarms and displays detailed fault information, enabling quick troubleshooting and minimizing losses caused by equipment downtime.
