Quality Control Facilities

Our quality department is a fully equipped facility.


Chemical analysis is taken from all of our foundry melts using a spectrograph.

This spectrograph is computer controlled and calibrated with 22 channels to ensure that the chemical elements meet the highest quality control requirements.

Mechanical Testing

We also have calibrated hardness and tensile test equipment to check the mechanical properties required.

Micro-photo analysis is undertaken on the finished machined castings. Most of the machining is carried out in our own machine shop. In addition to fettling and grinding, we undertake milling, slotting, turning and boring onsite. Other machining operations can be subcontracted to approved machine shops.
