Spectrometer
Optical emission spectrometry gives the full chemical composition (C, Si, Mn, P, S, Mg, Cu, Cr and more) in minutes.

01 Metallurgical laboratory
Four checks between melt and dispatch.
Each instrument checks one aspect of the iron, so we catch problems at the furnace.
CE analyser
Thermal analysis of a cooling sample gives carbon equivalent, carbon and silicon at the furnace, before the metal is tapped.

Micro image analyser
Metallurgical microscope with image analysis software for graphite form, nodularity, nodule count and ferrite / pearlite ratio.

Hardness tester
Brinell hardness testing of castings and test samples to confirm grade compliance and machinability.

02 Why it matters
The strength of SG iron depends on its nodules, so we measure them on every heat.
Tensile strength, elongation and impact resistance in ductile iron depend on graphite shape and matrix. Our micro image analyser quantifies nodularity and nodule count so each heat is released against your specification.
03 Sand laboratory
A complete sand lab, in-house.
Many casting defects start in the sand. We test system sand and cores daily so the moulding line runs inside its control limits.

04 Quality control plan
Six inspection stages on every order
Our ISO 9001 system defines what is checked, when and by whom, from raw material receipt to dispatch.
- 01
Raw material
Pig iron, steel scrap, returns and alloys checked and segregated by grade.
- 02
Melt control
CE analyser and spectrometer confirm chemistry before tapping.
- 03
Sand control
Daily GCS, permeability, moisture, clay and LOI testing.
- 04
First-off approval
First castings from each pattern inspected and reported.
- 05
Heat-wise testing
Microstructure and hardness recorded for every heat.
- 06
Final inspection
Visual, dimensional and machining checks before dispatch.
