In the world of precision manufacturing, the spotlight usually falls on the micron-level tolerances of a finished part. But when that part weighs 50 tons and spans 10 meters, the challenge isn’t just cutting the metal—it’s moving it.
For procurement managers sourcing contract manufacturing in China, the logistics of handling oversized components is often a major source of anxiety. How do you move a massive raw casting without cracking it? How do you flip a 30-ton weldment to machine the other side? How do you ship it across the ocean without it rusting?
At Openex, we believe that heavy machining logistics is just as much an engineering discipline as the machining itself. Here is a behind-the-scenes look at the journey of a massive component through our facility.
The process begins long before the first chip is cut. When a raw casting or forging arrives at our facility—often for the mining or hydropower industries—it can weigh anywhere from 20 to over 100 tons.
Standard forklifts are useless here. Openex is equipped with heavy-duty overhead crane systems with lifting capacities exceeding 50 tons (with tandem lifting capabilities for even heavier loads).
The Critical Step: Incoming Inspection
Before we lift a finger to machine, we must ensure the raw material is sound. Moving a massive casting requires a dedicated rigging plan. Our certified riggers inspect lifting lugs and determine the center of gravity to ensure a safe lift. Once offloaded, the raw part undergoes immediate dimensional and visual inspection to ensure sufficient "stock" material is present for machining.
The most dangerous time for a heavy part is not when it’s being cut, but when it’s being moved. A complex housing or frame might need to visit multiple stations:
Stress Relieving: Moving to our large-scale heat treatment furnaces.
Sandblasting: Transporting to surface preparation booths.
Machining: Loading onto our heavy-duty floor borers or gantry mills.
Flipping the Unflippable
Many large parts require machining on multiple faces. Flipping a 40-ton asymmetrical part is a high-stakes operation. We utilize specialized welding positioners and rotators, as well as engineered turning fixtures. This allows us to rotate massive components safely and precisely, preventing damage to the part (and protecting our team) while ensuring we don't induce new stresses into the metal.
Once the part is machined to precision, validated by our CMM inspection, and painted, it faces its final adversary: the ocean.
Transporting oversized machined parts from China to Europe, Australia, or the Americas involves weeks at sea in a high-humidity, saline environment. Standard packaging is a recipe for a rusted, rejected part upon arrival.
Openex employs a rigorous export packaging protocol for heavy cargo:
Anti-Corrosion Science: We utilize VCI (Vapor Corrosion Inhibitor) films and desiccants that create a chemical barrier against moisture. For critical machined surfaces, we apply heavy-duty rust preventatives that the customer easily removes but are impenetrable to salt spray.
Vacuum Sealing: For sensitive equipment, we foil-bag and vacuum seal the entire component.
Custom Steel Skids: Wood pallets crush under 50 tons. We fabricate custom structural steel skids designed specifically for the footprint and weight distribution of your part. This ensures that when the crane lifts the skid, the machined part experiences zero torque or twisting forces.
How does it leave the factory?
Open Top / Flat Rack Containers: For parts that fit within standard width/length but are too heavy or tall for standard boxes, we load them into Open Tops or secure them to Flat Racks using heavy-duty lashing chains.
Break Bulk: For the truly massive components (exceeding container dimensions entirely), we coordinate Break Bulk shipping. We transport the item directly to the port on low-bed trailers, where it is lifted individually into the ship’s hold.
We don't just have big machines; we have the infrastructure to feed them. When you choose Openex, you aren't just buying CNC time. You are buying a complete logistical solution that safeguards your investment from the moment the raw material arrives until it lands safely at your site.
Do you have a project that is too heavy or awkward for your local shop?

Contact Us for Heavy Fabrication Support
When manufacturing small components, the orientation of the machining process is rarely a logistical crisis. However, when you step into the world of heavy fabrication—dealing with parts that weigh 50 tons or span 5 meters in diameter—physics takes over.
At Openex, we frequently guide procurement managers and engineers through the decision-making process for manufacturing large-scale rotational parts. Two primary methods dominate this field: Heavy Horizontal CNC Turning and Vertical Boring (VBM/VTL).
While both processes remove metal to create cylindrical shapes, selecting the incorrect one for your specific component can result in tolerance issues, deformation, or unnecessary costs. Here is a breakdown of how we determine which machine is best suited for your project.
The single biggest factor in large-scale machining is gravity.
In a standard horizontal lathe, the workpiece is clamped at one end (chuck) and supported at the other (tailstock), often with steady rests in the middle. For a long, slender part like a ship’s propeller shaft, this is ideal. However, if you try to spin a massive, heavy ring horizontally, gravity pulls the suspended weight downward. This causes the part to "sag" or ovalize while it spins, making it nearly impossible to hold tight circular tolerances.
This is where the Vertical Boring Mill (VBM)—often called a Vertical Turret Lathe (VTL)—shines.
On a vertical boring mill, the workpiece sits on a rotary table that spins like a potter’s wheel. The cutting tool descends from a gantry above.
Best Applications:
Large Flanges & Rings: Wind tower flanges, bearing rings, and slew bearings.
Heavy, Short Cylinders: Turbine housings, pump casings, and valves.
Asymmetrical Parts: Heavy parts that are difficult to balance horizontally.
The Advantages:
Eliminating Sag: Because the part rests flat on the table, gravity works with the clamping system, not against it. The part maintains its natural shape, allowing for superior roundness and flatness.
Easier Loading: Loading a 40-ton casing onto a horizontal lathe is a rigging nightmare. Loading it onto a vertical table with an overhead crane is safer and faster.
Massive Capacity: At Openex, our large-scale vertical boring capabilities allow us to machine diameters that would be impossible on a horizontal lathe.
While vertical mills handle the wide and heavy, Heavy Duty Horizontal Lathes handle the long and slender.
Best Applications:
Propeller Shafts: For the marine industry.
Rollers: For paper and steel mills.
Tie Rods & Columns: For heavy presses.
The Advantages:
| Feature | Vertical Boring (VTL/VBM) | Horizontal Turning |
| Primary Part Shape | Disc, Ring, Short Cylinder | Shaft, Tube, Long Roller |
| Gravity Effect | Stabilizes the part (Safe) | Can cause sagging (Requires support) |
| Clamping Pressure | Lower (Gravity helps hold it) | Higher (Must fight gravity/centrifugal force) |
| Ideal Industries | Wind Energy, Hydro Power, Oil & Gas | Marine, Paper & Pulp, Steel Mills |
Many smaller machine shops only have one type of machine. If they only have a horizontal lathe, they will try to force your large ring onto it, risking quality.
At Openex, we operate as a true one-stop shop. Our facility is equipped with both massive floor-type boring mills and heavy-duty horizontal lathes, alongside our fabrication and welding divisions.
We analyze your drawing, calculate the weight and dimensions, and route your part to the machine that ensures the tightest tolerances and the most efficient cycle time.

Steel frames are the fabrication of raw steel materials into required form and shape for other industries through a sequence of activities such as design, cutting, bending, shaping, welding, and finishing. The resulting parts are such as building frames, bridges, and industrial machinery in accordance with exact blueprints and by employing specialized equipment so that the end product has the desired strength, durability, and dimension. Custom Metal Fabrication goes a step further by adapting such processes to meet the specific project needs, providing unmatchable benefit over mass-produced goods. For beam and column construction projects, tool and equipment production in industries, and structural components in commercial structures, optimized methods are provided by custom services. In this article, the top 10 benefits are highlighted and discussed, by virtue of which companies prefer them to achieve enhanced results.
Custom metal fabrication makes sure that all the components are made to precise specification eliminating the trial and error of pre-made components. With enhanced processes such as laser or waterjet cutting, fabricators have a precision of microns which ensures the smooth fusion into larger assemblies.
One of the significant benefits is that it can select alloys and treatments which can withstand extreme conditions, i.e., high temperatures, corrosion, or heavy loads. Custom pieces are designed to meet the environmental needs, as opposed to generic steel, which makes the products of higher quality and they need less maintenance.
Although initial impressions may be of greater initial expense, custom fabrication is more cost-effective by minimizing waste, optimizing production, and eliminating expensive rework. Fabricators take advantage of bulk material purchases and efficient procedure to transfer savings to the customer. This method is most valuable for high-volume applications where accuracy eliminates overruns.
Custom Metal Fabrication Services enable the innovative designs to be beyond the standard limitations and enable one to create their own shapes, sizes and features according to the creative visions. Such flexibility can be priceless to architects or engineers who want unusual appearance or utility.
Collaborating with experienced fabricators allows for access to premium materials and skilled methods to produce parts that surpass industry standards. Intensive focus in cutting, bending, welding, machining, and assembly yields outstanding workmanship that mass production is not capable of replicating.
By creating only what is required, custom fabrication reduces unnecessary waste of materials and inefficient operations. Not only does the environmentally friendly process save resources, but it also saves time because pieces are ready to be used without modification.

Modern manufacturing and construction is heavily reliant on metal fabrication. Starting with everyday household items such as teaspoons and giant structural elements, storage tanks and aerospace parts, made metals dominate thousands of industries. The knowledge of the processes, materials, and application of metal fabrication will enable businesses to select the most appropriate solutions and suppliers of their projects.
This guide covers the fundamentals of Metal Fabrication such as major processes, metals used, their application in various industries, and a few pieces of advice on how to select a China metal fabricator who is reliable.
Metal fabrication is the processes of fabrication to produce parts, components, and assemblies from raw metals. It entails different processes such as cutting, bending, shaping（forming）, machining, welding, and assembling to convert metal into end products.
Effectively, fabrication is science and art: precision tools and methods are needed alongside skilled craftsmanship in order to fulfill the exact demands of different industries. Here's metal fabrication processes:
Cutting is one of the initial processes utilized in metal fabrication. It is cutting a sheet of metal or a metal block to a specified size and shape.
Forming alters the shape of the metal but not the material. Presses or roll formers are used most often to form angles, arcs, and curves.
Welding joins metal components together permanently with heat and filler material.
Machining removes material from a workpiece to achieve accurate dimensions.
The last process is to put fabricated parts together into a final product. It can involve bolting, riveting, or welding, depending on the need of the design.
The selection of material is one of the most significant in the fabrication of metals. All metals possess unique qualities, e.g. strength, weight, corrosion resistance, and ductility that render them better in some applications than others.
The most common metal that is used in fabrication is steel by far. It is powerful, all purpose and fairly cheap which is why it is operational in both structural and industrial use. Steel can be easily cut, welded and machined by fabricators into beams, plate or complex parts. It lasts long making facilities such as bridges, buildings, and heavy machinery to sustain immense stress. Even carbon steel and alloy steel can be further tailored to suit taste on whether you need strength, wear resistance or toughness.
Aluminum is also appreciated in that it is light, yet it does not lose on strength. It weighs a third as much as steel and is indispensable in any industry where mass reduction is a desired efficiency factor, like the aerospace and automotive industries. The other major advantage is that it is natural resistant to corrosion thus made ideal in outdoor use, marine works and architectural designs. The formability nature of aluminum also enables fabricators to craft the material into complex shapes and the fact that it is highly conductive makes it handy in electrical engineering.
Copper is ductile and has excellent thermal and electrical conductivity. Copper is used in electrical wiring, connectors, and conductive components because of its unique properties. Copper's resistance to corrosion, and the proliferation of microbes it produces has made it a popular material for plumbing, roofing and medical equipment. Copper is more expensive than steel or aluminium, but its versatility and dependability make it worth the cost for special uses.
Stainless steel is nothing more than ordinary steel with an added advantage of chromium that offers excellent resistance to rust and staining. These three characteristics including strength, cleanliness and durability make stainless steel the preferred option in a setting where hygiene and beauty are valued. Stainless steel is an important component used in commercial kitchens, hospitals, laboratories, and food-processing plants. Stainless steel is also used in architectural projects due to its polished and modern look besides its functional use.
While less frequent in heavy usage, brass and bronze are still vital in specialty and aesthetic applications. Brass is a copper-zinc alloy that has a shiny goldish look and can be easily machined, and is therefore used as a fittings, musical instruments, and ornamental hardware. Bronze is a stronger and more lasting alloy of copper and tin, and was formerly employed in statues, bearings, and parts of ships, as it would not be corroded by sea water. The two metals provide a balance between functionality and aesthetics and this is what makes them remain alive in niche fabrication projects.
Metal fabrication penetrates virtually every sector of the economy. Some of the major applications are outlined below:
Shaped steel and aluminum are used extensively throughout the construction sector. Some examples are:
Industrial use involves high-strength, precisely manufactured parts that can withstand harsh conditions. These include:
Fabrication is also a key part of commercial products:
From solar to wind to oil and gas, fabrication forms the backbone of:
