Quality & Process Control
The quality you receive in Saudi Cast "SLIMLINE" castings is a result of a rigid control and attention on each step of the manufacturing process. Strict
adherence to process standards assures consistent quality, which is
considered to be very important to specifiers and owners.

As part of the "Quality & Process Control, the following test and inspection
points are implemented.

Thermal Analysis - Temperature of the metal throughout the melting cycle is checked. Also at this stage the Carbon & Silicon content is determined which will affect the strength of the material. The degree of nodularity is also determined

Spectrographic Analysis - Chemical analysis of the metal in the solid state is carried out to determine the exact percentage of all elements. This is conducted throughout the melting cycle using a Optical Emission Spectrograph.

Metallographic Examination - Determines the microstructure of the cast sample. This is done using a metallurgical microscope.

Mechanical Tests - Tensile testing of separate cast bars are assessed and compared to applicable standards.

Visual Inspection - All castings are inspected visually by our Quality Control Staff prior to dispatch to ensure compliance to specification and total freedom from defects.

As a final check and considered to be the most critical part of the whole
process is to assess the actual casting LOAD BEARING CAPABILITIES. Tests are conducted using a Compression Test Machine. All results are based on international standards and how the castings are classified according to load bearing capacities.

All above tests are done in-house. On request, Load Testing can be done
by a third party inspection body or can be witnessed in the presence of the
client and/or by the third party representative.
