Why This Route Exists
Cast iron remains the most economical answer for damping, wear resistance and complex cavities, provided the grade and the moulding route match the duty. Eurona covers grey iron, ductile iron and ADI materials.
Parts are matched to green sand, resin sand or shell moulding according to the customer drawing, the batch size and the application, which keeps tooling cost proportional to the order.
Published Specifications
These are the figures published for this process family. Values that depend on the specific part are confirmed during drawing review.

| ADI | ADI800-10 / ADI1200-3 |
| Weight Range | 0.2 kg - 2000 kg |
| Process | Green sand process; resin sand process; shell process |
| Selection Basis | Grade and moulding route matched to customer drawing and application scenario |
Process And Quality Capability
High volume production of repeat parts at the lowest tooling cost.
Larger parts and complex cavities where dimensional stability matters more than cycle time.
Better surface and dimensional accuracy for mid size batches.
What Usually Goes Wrong Without This Route
- A ductile iron part is ordered as GJS-500 but tested properties land below the grade.
- Wear parts are replaced far too often because ADI was never considered.
- Tooling is quoted for high volume moulding on an order of 200 pieces.

Cast Iron — Frequently Asked Questions
What weight range does cast iron cover?
0.2 kg - 2000 kg
Which materials are available for cast iron?
EN-GJL-150 / 200 / 250 / 300
Can machining and surface treatment be included?
Yes. CNC machining, dimensional control, surface treatment and necessary pre-assembly are coordinated in the same supply chain, so parts can be delivered finished to the drawing.
What is needed to get a quotation?
Drawings, material, quantity, quality standard and target delivery date. Those five items allow a process route and a suitable production base to be proposed.
