To meet the strict performance requirements for pipes in fields such as municipal engineering and gas transmission, Sumino Seiko's plastic extrusion equipment enables the stable production of high-pressure-resistant and high-corrosion-resistant pipes through multi-layer co-extrusion technology and intelligent temperature control systems.  

Highlights of Technological Upgrades  

Multi-Layer Composite Extrusion: Through a modular die head design, it realizes the simultaneous compounding of the smooth inner wall layer, middle reinforcement layer, and outer protective layer, significantly improving the comprehensive performance of the product.  

Vacuum Sizing Technology: Combined with precise water temperature control, it ensures that the pipe roundness and wall thickness uniformity meet higher standards.  

On-Line Inspection System: Integrates laser diameter measurement and defect detection functions to realize real-time identification and handling of quality issues during the production process.  

Solutions to Pipe Manufacturing Pain Points  

Bubble and Impurity Control: The multi-layer filtration system cooperates with the degassing device to effectively eliminate micro-pores and impurities in the melt.  

Longitudinal Fluctuation Suppression: The combination of a servo traction system and intelligent tension control prevents bamboo-like deformation.  

Cooling Stress Management: The design of multi-section cooling tanks and temperature gradient regulation reduces internal stress and improves dimensional stability.  

Typical Application Scenarios  

Gas Pipes: The product's pressure resistance and airtightness meet international standards, ensuring safe transmission.  

Municipal Water Supply Pipes: The co-extrusion technology of antibacterial coatings is adopted to improve the water quality and hygiene level.  

Industrial Pipeline Systems: It has excellent chemical corrosion resistance and can adapt to various harsh working conditions.  

Industry Observation: The safety and durability of pipe products largely depend on the process precision and stability of plastic extrusion equipment.
