Modern paper mills demand equipment that can operate non-stop at high speeds while resisting constant exposure to moisture, bleaching agents, and mechanical stress. Openex utilizes massive facility space and dedicated stainless steel fabrication areas to manufacture oversized, high-tolerance structural frames and pressure vessels exclusively for the global pulp and papermaking industry.
We provide pure, contamination-free welding of massive 304L/316L stainless steel broke pulper tanks, liquid media barrels, and heavy storage vats required to process corrosive pulp mixtures safely.
Exceptional stiffness and flatness are crucial to prevent paper web breaks. We fabricate and planer-machine extraordinarily long paper machine cantilever beams, rigid scanner frames, and massive water receiving pans.
Featuring 5-axis heavy CNC capacity to machine complex pulper rotor blades and bore deep-hole heat exchanger tube sheets, as well as vertical turning for dynamically balanced Yankee drying cylinders.
The number one cause of equipment failure in pulp bleaching and mixing is iron contamination causing localized galvanic corrosion. Because paper pulp reacts violently to impurities, stainless steel used in mill equipment must be pristine.
Our massive floor space allows us to completely separate 304L/316L stainless fabrication from our carbon steel processing, preventing iron dust from settling into your paper mill equipment.
High-speed components like rotor vanes and large drying cylinders undergo strict dynamic balancing and precision surface grinding to guarantee completely vibration-free paper winding operations.
