Resources & FAQ

Lamellar graphite (GL) cast iron offers good castability and excellent vibration-damping properties. It is suitable for frames, casings and structures subjected to continuous loads.

Ductile iron (GS) offers superior mechanical strength and ductility, making it suitable for components subjected to impact or dynamic stresses.

Austempered cast iron (ADI) combines high strength, toughness and wear resistance, and is used for the most mechanically demanding applications. The choice of grade is determined through co-design or in accordance with the requirements set out in your specifications.

We produce parts weighing between 0.1 kg and 600 kg.

Pig iron is susceptible to corrosion in damp environments. Surface treatments, such as epoxy paint and anti-corrosion coatings, can be applied through our network of partners. The choice of treatment is determined by the environment in which the component will be used.

Yes, in many cases. Cast iron offers specific advantages, such as castability, damping, cost of materials, which make it a viable alternative to cast steel, aluminium, or the mechanically welded assemblies for certain applications.

Our technicians methods analyse the feasibility and the mechanical implications right from the co-design phase.

Yes. We produce prototypes, including using 3D sand printing for moulds and cores, without the need for dedicated tooling. This is a useful step for validating a part’s geometry and/or performance before starting series production.

From 5 to 10,000 units per year, depending on the product. Our organisation caters for both small and medium-sized production runs.

Yes, entirely. The design of the moulds and core boxes is carried out in-house using SolidWorks. The manufacture of the tooling is also coordinated by our teams. This enables us to manage lead times and ensure consistency between design and production.

Yes. If you provide us with an existing component or a drawing, our technicians will assess its suitability for casting and, if necessary, propose a redesign focusing on cost and performance, geometry, material grade and wall thicknesses. The aim is to optimise the component for the casting process without compromising its functional performance.

No. Depending on the scope defined at the outset of the project, we can supply a raw component in accordance with the drawings, or a fully finished component that has been machined, heat-treated, painted and assembled, ready for installation on the production line. This scope is defined at the project planning stage.

The tolerances for rough castings from foundries are defined in accordance with the standard ISO 8062. We achieve class DCTG 9, which represents a < a15> level of precision high for foundry work cast iron. Machining allowances are defined during the design phase to ensure accessibility to the required final dimensions.

As a general rule, the recommended minimum wall thickness for cast iron is 7 mm, depending on the grade and geometry of the component. Thinner walls are technically feasible for certain configurations, but require a prior feasibility analysis. This is a point that is systematically checked during the design phase.

In green sand casting, a 2° draft angle is required on the demoulded surfaces. On parts formed using cores, this value is reduced to 1°. These values can be adjusted depending on the height and complexity of the geometry. Our process engineering department checks and approves the draft angles during the feasibility analysis.

Undercuts are produced using the core-making process. We have four core-making machines: three automatic Laempe machines (5, 20 and 40 litres) and one manual Alphaset machine for large cores or those with complex geometries.

The design of the boxes for nuclei is entirely carried out in-house.

That said, undercuts have a direct impact on the cost of the part. Our process engineers can help you minimise them right from the co-design phase, to achieve a more cost-effective solution without compromising on functionality.

Yes. We use the Nova Flow software to support the technical expertise of our process engineers. Simulation enables us to ensure the reliability of the gating and feeding processes for complex components, and to anticipate the risk of sink marks or porosity before production begins.

Yes, subject to a feasibility assessment carried out as part of the co-design process. The integration of metal inserts is possible, depending on the nature of the insert, its position within the component and the thermal constraints associated with the casting process.

ISO 9001 for the quality management system. Marine certifications issued by Bureau Veritas, Lloyd’s Register, DNV and ABS for naval applications. EcoVadis for the assessment of our CSR performance.

Every item is traced from the raw material right through to delivery. Spectrometric analyses, production parameters and inspection results are documented and archived. This traceability is available for every order on request.

We carry out a range of inspections for dimensional accuracy, using ultrasound, penetrant testing, magnetic particle testing and radiography. The methods used depend on the requirements of the specification and the standards applicable to each sector.

Yes, using equipment appropriate to the complexity of the part: conventional tools and Faro 3D measuring arms for complex geometries. The frequency and methods of inspection are defined in accordance with the monitoring plan associated with each part number.

Yes. Dimensional inspection reports, material certificates (3.1 and 3.2) and the results of non-destructive testing can be provided in accordance with the requirements of the specifications.

We deliver throughout Europe.

Yes. We can arrange for the goods to be delivered directly to your site. The arrangements are determined on a case-by-case basis, depending on the project and the destination.

This is a matter best discussed directly with our sales teams, depending on your specific requirements. We adapt to our customers’ supply constraints for recurring items.
