1. High-efficiency extrusion forming: The extrusion mechanism is capable of steadily conveying raw materials and heating them to achieve plasticization, ensuring uninterrupted and homogeneous parison extrusion that caters to the molding demands of solar water tank liners with various specifications.
2. Accurate wall thickness regulation: Equipped with a MOOG-style parison thickness adjustment system, it can precisely modify the wall thickness of each part of the parison based on the liner structure and stress requirements, preventing local under-thickness or over-thickness issues and enhancing product quality and durability.
3. Stable mold clamping and injection: The accumulator injection system operates in coordination with the mold clamping mechanism, and the clamping force is matched to different machine models. This ensures tight mold closure during the liner forming process, precise injection volume, and reliable product dimensional accuracy.
4. Intelligent temperature control and cooling: Multi-stage temperature regulation of the die head guarantees optimal raw material plasticization; the cooling system rapidly chills the formed liner, shortening the production cycle and boosting production efficiency.
5. Fault and status monitoring: The PLC control system keeps real-time track of equipment operating parameters. In the event of a malfunction, it can promptly trigger an alarm and display fault details, facilitating quick troubleshooting and minimizing downtime losses.
1. Cost Benefit: In contrast to enamel inner liner manufacturing equipment, the plastic hollow inner liners produced by this machine feature lower raw material expenditure and higher forming efficiency, enabling a reduction in overall production expenses. When compared with stainless steel inner liners, plastic liners offer superior thermal insulation, cutting down energy consumption costs during post-operation.
2. Quality Superiority: It achieves accurate wall thickness control, resulting in liners without welding seams, excellent sealing performance, corrosion resistance, and anti-aging properties, thereby prolonging the service lifespan. Adopting accessories from renowned brands, the equipment maintains stable operation and lowers the defective product rate effectively.
3. Operation & Maintenance Merits: Equipped with full-automatic control and an intuitive human-machine interface, the machine is easy to master for operators. Its rational structural design facilitates convenient maintenance, coupled with timely after-sales support, which helps enterprises reduce operation and maintenance costs.
4. Customization Capability: We can customize models of various specifications based on customer requirements, applicable for producing inner tanks ranging from 120L to 1500L. This enables the machine to cater to the differentiated demands of different solar water heater manufacturers.
1. High Specialization
Exclusively engineered for solar hollow inner liners, every component is tailored to the inner liner manufacturing workflow. In contrast to universal blow molding machines, it delivers superior molding precision and higher production efficiency.
2. Cutting-edge Technology
