Quality
Controlled at every stage
Control starts with the liquid metal and ends with the finished casting on test. The result is a casting whose composition and properties can be traced.

Liquid metal control
Temperature and chemical composition are checked before and during pouring, by thermocouple and by express analysis equipment.

- Spectrometer for express analysis of the sample
- Ferrolab and Siderlab express analysis devices
- Temperature measurement by thermocouple
