The service life of a screw press is a critical indicator of its economic viability, primarily determined by three aspects: material selection, structural design, and manufacturing processes.

   Materials form the foundation. Core components like the screw shaft and stacking plates endure prolonged contact with complex sludge compositions, demanding exceptional wear and corrosion resistance. Jiangsu Longdai Environmental Protection Group Co., Ltd. leverages its materials laboratory to select and apply specialized alloys and stainless steel materials. Key surfaces undergo enhanced surface treatments, significantly boosting the durability of critical moving parts.

   Design is pivotal. Rational structural design effectively distributes operational stresses, reducing fatigue and vibration. The company's R&D team utilizes advanced design analysis tools to optimize equipment structures, enhancing overall stability and balance while preventing premature damage caused by prolonged vibration. Additionally, adaptive design features enable the equipment to maintain high-efficiency operation even after normal component wear.

   Process is the guarantee. Precision manufacturing processes directly determine assembly accuracy and operational smoothness. On Longdai Environmental's in-house production lines, core components are machined using high-precision CNC equipment, ensuring strict tolerance control. Rigorous assembly procedures and comprehensive factory testing guarantee the reliability of every delivered unit.

   This end-to-end self-control capability—from materials to processes—enables the company's equipment to demonstrate outstanding durability in projects exported to numerous countries. Concurrently, local factories support rapid provision of compatible spare parts, further safeguarding the equipment's full lifecycle operation.
