Suction Box

The suction box is a key dewatering component for paper‑making equipment, including single‑slot suction box and paper machine suction box. It is mainly used in the paper sheet forming section to dewater wet paper web by negative pressure. It is welded from corrosion‑resistant plates, going through complete procedures including welding flaw detection, precision machining, sealing treatment and surface protection.

With well‑optimized box structure, it ensures even distribution of vacuum negative pressure and stable dewatering performance. It features excellent structural rigidity, low deformation during operation and reliable sealing performance to prevent air leakage, so as to guarantee good forming quality of paper sheets.

Deep non‑standard customization is available. We can carry out personalized design and production in accordance with customer equipment parameters, installation dimensions and working‑condition requirements. All finished products are strictly inspected before delivery. Product warranty, full‑set technical consultation and after‑sales support are provided for various paper machine models.
