SYNCO Roll Etching Machine
Precision Surface Etching for Industrial Rolls
The?SYNCO Roll Etching Machine?is a specialized surface-treatment system designed for?controlled chemical etching and texturing of cylindrical rolls. Engineered for accuracy, repeatability, and safety, the machine delivers?uniform etch depth and surface patterning?essential for rolls used in coating, printing, laminating, embossing, rubber processing, paper, and steel industries.
Process Overview
The roll is mounted on powered supports and rotated at a?controlled RPM?while?etchant spray nozzles?(fixed or oscillating) uniformly treat the roll surface. Precise control of?rotation speed, spray pressure, exposure time, and chemistry?ensures consistent surface roughness and pattern definition along the full roll length.
Key Features
1) Powered Roll Rotation
- Smooth, vibration-free rotation with variable speed drive
- Uniform exposure of entire circumference
- Suitable for light to heavy rolls
2) Multi-Nozzle Etching System
- Multiple spray nozzles arranged longitudinally
- Uniform chemical distribution across roll face width
- Nozzles compatible with aggressive etchants
3) Axial Nozzle Traversing / Oscillation (Optional)
- Reciprocating movement along roll length
- Eliminates banding and uneven etching
- Adjustable stroke and speed
4) Chemical-Resistant Enclosure
- FRP / PP / PVC / rubber-lined steel construction
- Fully enclosed chamber for operator safety
- Easy access doors with safety interlocks
5) Process Control & Safety
- Controlled etchant flow and pressure
- Drainage and recovery system
- Fume extraction / scrubber connection
- Emergency stop and interlocked operation
Typical Applications
- Texturing of coating & laminating rolls
- Printing & gravure roll surface preparation
- Rubber, PU & polymer processing rolls
- Steel, aluminum & specialty alloy rolls
