Manufacturing process
Six stages with clear checkpoints.
Inspection details and documentation can be aligned to the machine specification and destination.
Technical review
Material, diameter, output, chip use, climate and mobility requirements are checked before configuration.
Cutting and welding
Structural parts are prepared and assembled against production drawings and agreed specifications.
Surface treatment
Parts move through preparation and coating steps for a consistent industrial finish.
Component integration
Feed system, rotor, engine, hydraulics, controls and discharge are installed as one system.
Function checks
Operation, feeding, controls and safety functions are reviewed before the agreed inspection.
Packing and documents
The machine is prepared for shipment with the confirmed accessories and destination documents.
What we check
Quality is a sequence, not a final glance.
The exact inspection scope is defined by the model, configuration and order agreement.
Machine and structure
Key dimensions, welds, guards, fasteners, finish and the ordered mobility configuration.
Feeding and cutting
Feed direction, hydraulic response, rotor operation, knives and access for routine maintenance.
Power and controls
Engine setup, instruments, load-management functions and agreed electrical or control options.
Shipment readiness
Accessories, manuals, spare-parts list, packing and documentation checked against the order.

See before it ships
Make inspection part of the order process.
Ask for operating footage or arrange a live video, in-person factory visit or third-party inspection. Timing and scope should be confirmed before production is completed.
