Established in Changsha in 2008, REALJET connects metal fabrication, machining and mechanical assembly around the equipment drawing.
Explore our processes

Cut and formed parts become welded structures. Machining establishes the interfaces. Finishing and fit checks complete the agreed supply condition.



Plan the fabrication around the drawing’s material, joint access and assembly geometry. Choose individual parts or a defined welded structure.
G6020-series laser equipment · WE67K-series press brakes · robotic welding stations



Mounting faces, locating bores and fixing patterns establish how your component joins the equipment. For weldments, the machining route accounts for fabrication and datum transfer.
FV3219 and XKW2328 gantry equipment · machining centres · boring equipment



Finish and assembly requirements are part of the manufacturing scope. Define exposed surfaces, protected interfaces, supplied hardware and the conditions for release.
Blasting, coating and painting resources · mechanical assembly provision
Share the material, drawing datums and critical dimensions so the machine envelope, clamping and inspection route can be reviewed for your part.

The interface requirements change from one machine to another. Define what the part locates, supports and connects.

Joining sequence, structural fit-up and post-weld machining for machinery components.
Explore machinery components ↗Drawing-defined mounting datums, fixing access and mechanical interfaces around the robot designer’s requirements.
Custom metalwork for battery production, energy storage, EV charging and solar equipment.
Explore battery and energy components ↗Locate the workpiece, actuator and inspection equipment against the assembly layout.
View an inspection-station frame ↗Fabricated and machined components built to the specified support, access and assembly interfaces.
Explore AI equipment components ↗Steel structures are a core part of our fabrication work. For aluminum alloy, stainless steel and alloy steel, the grade and supply condition set the route for forming, joining, machining and finishing.
Machined plates, brackets and formed components reviewed by alloy, temper, geometry, joining method and finish.
Specify the alloy and temper, mating requirements and surface treatment.
Components with specified corrosion resistance and surface requirements. Coordinate forming, joining and contamination control.
Specify the grade, surface finish, weld requirements and cleaning condition.
Structural and machined components with defined strength, toughness or wear requirements, reviewed against the supplied material condition.
Specify the grade, heat treatment, welding requirements and machining condition.

Include the material specification and delivery condition with the drawing, so the manufacturing review starts from the same requirement.
Link the drawing revision, material, process stages and final condition in an agreed inspection plan. Decide the records required before manufacturing starts.
Confirm revision, datums, critical dimensions, material condition and the certificates required by the order.
Plan checks after forming, tack-up, welding and machining where those operations can change the accepted geometry.
Select a measuring method suited to the feature, part size and tolerance. Agree support conditions and any mating fixture.
Review weld appearance, surface condition, masking, cleanliness, identification and packing against the delivery scope.
Available resources include PMT ALPHAm articulated measuring equipment, hardness testing and dimensional gauges. Select the instrument, support condition and measuring range against the agreed check, with suitable calibration status and measurement uncertainty.
Confirm the required documents and acceptance criteria in the quotation scope.
