cdocastChoose The heavy duty rolling mill ,Inquity Now!
The CDOCAST high-power rolling mill is designed for heavy-duty sheet and strip reduction in gold, silver, platinum, palladium, copper alloys and compatible non-ferrous materials. The CDO-RM30, CDO-RM40 and CDO-RM50 combine 22–37.5kW drive power with wide Cr12MoV rolls for repeated industrial production.
Select the machine from the incoming slab, maximum sheet width, starting thickness, target thickness, alloy, reduction schedule and required daily output—not from motor power alone.

Heavy precious-metal slabs demand more than a larger motor. A practical industrial rolling mill needs a rigid frame, stable drive transmission, correctly sized rolls, repeatable gap control, adequate lubrication and a reduction schedule that matches the metal. The CDO-RM series is intended for factories that repeatedly reduce thick gold, silver or alloy stock into sheet and strip, where a small workshop mill would be slow or overloaded.
The drive system supplies the torque needed for repeated reduction of wide or thick stock. The correct model depends on material strength, section size, pass reduction and duty cycle.
HRC 60–62 roll hardness supports wear resistance and long service life. Clean, correctly maintained roll surfaces help reduce scratches, contamination and avoidable precious-metal loss.
Roll diameters of 220–260mm and listed working widths of 380–500mm support wider sheet production. Frame rigidity and roll alignment remain essential to thickness consistency.
The source specification uses grease-lubricated bearing bushes. Lubrication points, intervals and approved grease should be included in the maintenance plan.
22kW motor with Φ220 × 380mm rolls. Listed for a 35–0.35mm sheet-thickness range.
Best starting point for: factories needing heavy rolling capacity with a narrower working width.
30kW motor with Φ240 × 440mm rolls. Listed for a 40–0.4mm sheet-thickness range.
Best starting point for: regular high-volume sheet production requiring balanced width, power and machine footprint.
37.5kW motor with Φ260 × 500mm rolls. Listed for a 50–1mm sheet-thickness range.
Best starting point for: wider and heavier incoming stock where maximum listed width and drive power are required.

Confirm destination voltage, control configuration, actual usable roll width, maximum admissible entry section and acceptance method before ordering.
Reduce gold, karat-gold and silver stock into sheet for fabrication, stamping, blank preparation and subsequent forming.
Prepare silver alloy, copper alloy, platinum solder foil and compatible strip where thickness control supports downstream reliability.
Produce wider experimental alloy sheet and repeatable intermediate material for research, testing and process development.
Convert remelted precious-metal ingots and recycled alloy feed into sheet for further processing, sampling or product manufacture.
A rolling mill forms solid feed; it does not melt, cast or refine contaminated metal. A practical production route may begin with a precious metal continuous casting machine to prepare repeatable plate or strip blanks, followed by controlled rolling and annealing. If the required product is wire rather than sheet, compare the grooved-roll configurations on the jewelry wire rolling machine page.

Please provide these six items so CDOCAST can select the machine and prepare a meaningful quotation:
The following details improve engineering accuracy but do not need to delay the initial inquiry:
Start from the maximum incoming thickness, required sheet width, alloy strength, pass reduction and production duty. RM50 has the largest listed roll size and motor, but a larger machine is not automatically the best economic choice for narrower or lighter material.
No. The listed range does not mean one-pass reduction. Thick stock requires multiple controlled passes, measurement between passes and annealing when required by the alloy and work-hardening condition.
The series is intended for precious metals and compatible non-ferrous alloys, but rolling force, reduction schedule, annealing and surface requirements vary. Send the actual alloy and starting section for confirmation.
No. Output also depends on stock dimensions, alloy, reduction per pass, operator method, annealing time, handling, inspection and downtime. Capacity should be discussed using a defined product and production cycle.
The supplied photographs show a 40P CNC configuration, but the final control functions, measurement method and automation scope must be stated in the quotation. Do not assume every configuration is identical.
Roll condition and alignment, frame rigidity, gap setting, material uniformity, pass schedule, temperature, work hardening and measurement method all affect the result. Agree on a sample, measurement locations and acceptance procedure.
Send CDOCAST your alloy, incoming slab dimensions, maximum sheet width, starting and final thickness, tolerance, daily production goal, destination voltage and preferred control system. We can then recommend the correct RM30, RM40 or RM50 configuration and supporting production equipment.
Technical note: Specifications are based on the supplied product data. Final machine configuration, performance conditions, safety scope and acceptance criteria are confirmed in the quotation and technical agreement.
