Assembly & Integration

Fully Integrated, Ready-to-Install Assemblies

When outsourcing massive industrial components, piecing together parts from multiple vendors invites logistical nightmares and costly tolerance failures. At Openex, our manufacturing cycle doesn’t stop at welding and machining. Our dedicated, massive-scale assembly hubs turn individual components into fully functioning, field-ready machinery.

Operating within our 180-acre facility, our assembly floors boast high roof clearances and massive 250-ton gantry cranes. We handle everything from the precise fitting of high-tolerance bearings and large gearboxes to the structural trial assembly of massive offshore helidecks. By assembling everything completely in-house, we ensure flawless "plug-and-play" installation upon delivery to your job site.

Complete System Integration Stages

Structural Trial Assembly

Massive fabricated components—like steel bridges, tower cranes, and mining hoppers—often cannot ship fully assembled due to freight limits. We conduct comprehensive full-scale dry runs on our floor to ensure every bolt aligns perfectly before disassembling and packaging for export.

• ✔ Total tolerance and clearance verification.
• ✔ Match-drilling of connecting mating points.
• ✔ Fast, defect-free onsite construction.

Precision Mechanical Fitting

For complex rotating equipment, precise fits are critical. Our specialized fitters meticulously assemble heavy internal components with micron-level tolerances inside our climate-controlled staging zones.

• ✔ Bearing press-fitting and seating.
• ✔ Complex gearbox casing assembly.
• ✔ Large pump, rotor, and drive shaft installation.

Fluid & Systems Integration

Why stop at structural frames? Our integration teams are equipped to pipe, route, and cable industrial equipment, converting bare structural weldments into functional operational skids.

• ✔ Routing and connecting high-pressure piping.
• ✔ Hydraulic and pneumatic valve systems mounting.
• ✔ Instrumentation panels & electrical routing.
