cdocastBuy the Most advanced Double Head Rolling Machine for Wires&Strips
Two rolling heads · one compact machine
The CDOCAST double head rolling machine combines two rolling stations in one cast-frame unit. It can be configured for sheet and wire rolling, two wire rolling heads, or two strip rolling heads to match precious metal processing requirements.
Rolling head arrangements
Select the roller combination according to the material forms handled most often in your jewelry or precious metal workshop.
One flat rolling head for reducing sheet or strip thickness and one grooved head for reducing and forming wire. This is the most flexible arrangement for mixed jewelry production.
Two grooved rolling heads support wire-size reduction and section-forming tasks at separate stations. Roller groove profiles can be discussed according to the required wire shape.
Two flat rolling heads provide two sheet-rolling positions in one machine footprint. This double head sheet rolling mill arrangement is suited to workshops that primarily process metal strip and sheet.
Available models
This industrial precious metal rolling machine range covers 5.5 kW, 7.5 kW and 11 kW drive options with progressively larger rollers and wire inlet sizes.
Compact model with Φ132 × 228 mm rollers for sheet-and-wire jewelry rolling operations.
Mid-range model using Φ151 × 250 mm rollers for larger starting wire sizes and routine precious metal production.
Larger model with Φ180 × 250 mm rollers for heavier wire reduction and higher-capacity rolling work.
Technical data
Compare the three standard models. Final roller configuration and electrical supply should be confirmed before production.

Machine details
The mechanical layout keeps both rolling heads accessible while placing adjustment and operating controls close to the working area.
Two rolling heads are integrated into one frame so sheet and wire processes can be arranged at separate stations without installing two independent machines.
The handwheel adjusts the roller position for controlled reduction. Operators should use progressive passes appropriate to the metal and required final dimensions.
The panel groups the principal machine controls in a clear operating position for starting, stopping and managing the rolling process.
Product capabilities
The dual-head arrangement reduces floor-space demand compared with installing two separate floor-standing rolling machines.
The integrated frame supports the two roll stands and drive system, providing a stable mechanical base for metal reduction.
Flat and grooved roller combinations can be selected around sheet, strip and wire processing requirements.
Standard models provide different motor power, roller diameter, inlet wire size and machine footprint options.
For a dedicated sheet-production layout, see the metal strip rolling mill. Workshops focused mainly on wire sizing can compare the jewelry wire rolling machine.
