Openex details logistics for large-scale machining from casting to delivery

Openex Mechanical Technology Ltd. outlined the handling, packaging and shipping steps it uses for oversized machined parts in China, from the arrival of raw castings to export delivery. The company framed logistics as a core part of precision manufacturing for heavy components used in mining, hydropower and other industries.

Why it matters: - Large machined parts can weigh 20 to more than 100 tons, so handling mistakes can damage the part, delay delivery or create safety risks. - Openex says the logistics process is part of the engineering challenge, not just transportation. - For procurement teams sourcing contract manufacturing in China, packaging and shipping can determine whether a finished part arrives usable or rejected.

What happened: - Openex Mechanical Technology Ltd. described how a massive component moves through its facility, from raw casting or forging arrival to export delivery. - The company said the process is designed for oversized parts used in mining and hydropower applications. - Openex said it uses heavy-duty overhead cranes with lifting capacities above 50 tons, including tandem lifting for heavier loads. - Certified riggers inspect lifting lugs and locate the center of gravity before a lift. - Incoming parts are checked for dimensions and visual condition to confirm enough stock remains for machining.

The details: - Internal handling can send a part to stress relieving furnaces, sandblasting booths or heavy-duty floor borers and gantry mills. - Large parts that need machining on multiple faces may be rotated with welding positioners, rotators and engineered turning fixtures. - Openex said those systems help prevent damage, protect workers and avoid new stresses in the metal. - Finished parts are validated by CMM inspection and painted before export. - Export packaging uses VCI films and desiccants to block moisture. - Critical machined surfaces get heavy-duty rust preventatives that can be removed by the customer. - Sensitive equipment may be foil-bagged and vacuum sealed. - Openex fabricates custom structural steel skids for parts too heavy for wood pallets. - The skids are designed to keep the part stable and avoid torque or twisting when lifted. - For shipping, Openex uses Open Top or Flat Rack containers when parts fit standard dimensions but need special handling. - For larger components that exceed container dimensions, the company arranges break bulk shipping. - Break bulk cargo is moved to port on low-bed trailers and loaded individually into a ship’s hold.

Between the lines: - The process shows how much value in heavy manufacturing sits outside the machine itself. - For oversized parts, rigging, corrosion protection and shipping method are part of product quality. - Openex is positioning its logistics capability as a differentiator for customers that need a full manufacturing-to-delivery workflow.

What’s next: - Openex is inviting customers with heavy or awkward projects to request a consultation for large-scale manufacturing needs. - The company is marketing itself as a single-source option for CNC production, packaging and export logistics. - Openex included contact information for heavy fabrication support: +86 186 5928 0806.
