Grey and ductile iron, cast, machined, inspected and delivered by a foundry that engineers its own process control. Here's how we decide the right iron, and how a part actually gets made.
Every casting we make also teaches us something about the machines and processes behind it — and everything we learn from building foundry equipment finds its way back into how we cast. The two sides of what we do have never really been separate; they just show up as different pages on this website.
The choice of iron is the first engineering decision on any casting. Tell us how your part is loaded and we'll point you to the right family and grade — the way our engineers would on a call.
This is a starting point — final grade depends on section thickness, machining and your full spec. An engineer confirms it on your drawing.
| Grade | Family | Typical UTS | Character | Typical use |
|---|---|---|---|---|
| FG 200 | Grey iron | 200 MPa | Great damping & machinability | Housings, covers, bases |
| FG 260 | Grey iron | 260 MPa | Higher-strength grey | Loaded structural bodies |
| SG 60-40-18 | Ductile iron | 400 MPa | Tough, high elongation | Impact & safety parts |
| SG 65-45-12 | Ductile iron | 450 MPa | Higher strength ductile | Load + fatigue duty |
Shrinkage, gas porosity, inclusions and dimensional error. Our whole line is built to catch each one before it reaches you.
Sorted scrap is weighed to a calculated charge and melted in induction furnaces to the target chemistry.
Before a drop is poured, chemistry is confirmed within grade spec.
→ Why: wrong chemistry means wrong properties in every casting from that heat. Nothing pours until it passes.Green sand is mixed to controlled moisture, then compacted around the pattern on a high-pressure moulding machine for a dense, repeatable mould.
Cores are set for internal passages, the mould is closed and clamped against the metal pressure to come.
Metal fills through a gating system designed to fill fast but calm; risers feed the casting as it shrinks during solidification.
Once cooled on a controlled curve, castings are shaken out, and gates and risers removed.
Shot blasting cleans the surface; machining brings critical features to tolerance; finishing as specified.
Dimensional and visual inspection confirms the part is right.
→ Why: a defect is cheapest to catch here — never at your assembly line.We give DFM feedback on wall thickness, draft and section junctions before tooling is cut — so problems die on paper, not in metal.
A clear quotation process, honest lead times and a foundry that controls its own equipment uptime.
Spectrometer verification and inspection are steps we show you, not claims we make.
Upload your casting drawing and an engineer reviews it — including any DFM notes worth flagging — before you get a number.
