Flat Steel Moulds (FSM)
Description
The SYRO flat steel moulds are made of European steel and are produced in Switzerland and Germany.
Application
SYRO flat steel moulds are especially dedicated to fibre cement and CBPB manufacturers.
Tolerances
The SYRO flat steel moulds are available in the following dimensions with standard tolerances. Tolerances, which differ from the standard ones must be requested.
| Dimensions | Standard Tolerances | |

Production Process
The production process for the SYRO flat steel moulds includes:
- Trimming of steel plates to its required width
- Oiling with corrosison protection oil
- Deburring and rounding of rough edges
- Wrapped in double-sided VCI foils
- Packed into wooden boxes
Product Quality
In order to guarantee the top quality of the SYRO steel moulds
- The tolerances are constantly checked during the production process
- The moulds are handled with utmost care and are protected with oil
- The moulds are carefully packed in to VCI foils and wooden boxes
