Drawing and interfaces
Revision, dimensions, mating features, samples and unresolved points.
Company-owned manufacturing bases
ROCKVANTA owns and operates five specialized manufacturing bases. Our team reviews each project, assigns the relevant base and coordinates any supporting processes, inspection and export preparation.


Figures describe the combined scale of the ROCKVANTA industrial manufacturing network. Base selection, available capacity and process coverage are confirmed for each RFQ.

Current drawing, approved sample and interface review
Base selection
ROCKVANTA reviews the drawing, material, required processes, inspection and delivery requirements, then assigns the relevant manufacturing base for the project.
Revision, dimensions, mating features, samples and unresolved points.
Grade, supplied condition, hardness or treatment requirements where applicable.
Machining, fabrication, forming, welding, assembly and supporting operations.
Critical checks, hold points, documents and third-party attendance where required.
Quantity, schedule target, destination, packing and handover requirements.
Plate and tube cutting, CNC machining, forming, welding and heat treatment are available in-house at XuZhou ELT Mechanical Equipment Co., Ltd. Send the part drawing and required operations so we can confirm the equipment and manufacturing sequence for your order.

Manufacturing capabilities
ROCKVANTA coordinates CNC machining, fabrication, conveyor-component production and heat treatment according to the confirmed part, material and inspection requirements. The project plan identifies the selected base and any supporting processes.

CNC machining and supporting-process review
Medium-to-large parts, shafts, housings and drawing-defined interfaces are reviewed around the part envelope, material, setup access, datums and inspection needs.

Fabrication and downstream-operation review
Frames, brackets, structures and welded assemblies are reviewed around material sections, joint definition, fixture needs, distortion control and downstream operations.

Product-specific production and inspection review
Rollers, idlers, pulleys, frames and rebuild components are produced from the approved component definition and required product checks.

Applicable treatment and verification review
Treatment methods are selected from the material, supplied condition, treated zone or whole-part requirement, and the operations that follow.
Project coordination
Each project is reviewed separately. Available capacity, lead time, process coverage and required records are confirmed during RFQ review.
Confirm the drawing, material, process, inspection and delivery requirements.
Match the job to the relevant equipment, processes and available capacity.
Coordinate supporting processes, inspection points, documents and handoffs.
Keep the agreed records, identification, packing and export preparation with the order.
Production environments
These photographs show representative production and packing environments. Equipment, process availability and capacity are confirmed for the specific RFQ.



Project documentation
Tell us which material certificates, inspection reports, test records or third-party attendance your project requires. We will review the proposed production plan and confirm the document package in the quotation.
If a certificate or qualification is requested, it is supplied for the named legal holder and original certified scope. Public copies are redacted where required, and availability is confirmed for the specific order.
Material certificates and traceability records
Dimensional, hardness, NDT or product-specific reports
Third-party inspection timing and scope
Document format, language and release point

Agree required records and inspection points before the order is released.
Selected work for equipment manufacturers, conveyor businesses and mining projects.
