MANUFACTURING

How we cast.

The workshop route follows the actual casting floor: wax injection, wax repair, tree assembly, automatic shell making, dewaxing, pouring and post-processing. RFQs can be routed through low-temperature wax casting, medium-temperature wax casting or sand casting.

Low-temp wax castingFor stable batch parts where route efficiency and repeatability matter.

Medium-temp wax castingFor tighter surface, dimensional and alloy-control requirements.

Sand castingFor larger industrial components that need resin-sand or water-glass sand molds.

Wax injection presses at Renyi — Wax injection workshopWax patterns are formed on dedicated injection presses.

Wax pattern repair at Renyi — Wax repair workshopParting lines and surface details are repaired before assembly.

Wax tree assembly at Renyi — Tree assembly workshopPatterns are gated and grouped for shell building.

Automatic shell-making line at Renyi — Automatic shell lineRobotic slurry and sand steps build repeatable ceramic shells.

Dewaxing furnace operation at Renyi — Dewaxing workshopShells are dewaxed and heated before pouring.

Molten metal pouring at Renyi — Pouring workshopHeat and pour control link the shell to the final casting.

Post-processing workshop at Renyi — Post-processing workshopCleaning, cutting, grinding and transfer steps prepare castings for inspection.

CAPABILITIES

Built around the part—not a catalogue.

Process route, machining scope and inspection plan are confirmed against each drawing during RFQ review.

Investment casting

Silica-sol and composite-process casting for detailed components.

Sand casting

Resin-sand and water-glass routes for larger industrial castings.

CNC machining

Rough and finish-machined delivery options.

Inspection

Inspection planning can include spectrometer material analysis, mechanical testing, magnetic-particle testing (MPI), ultrasonic testing (UT) and radiographic testing (RT).

QUALITY RECORDS

Records that support technical review.

Renyi maintains ISO 9001, ISO 14001, ISO 45001 and CE/PED PCM-4.3-PED qualification records. Inspection scope is confirmed against each drawing and RFQ.
