How we deliver

Move faster with precision and expertise

Accelerate your future development projects through an efficient process built on deep industry knowledge and advanced technology that will provide you with fully functional components from first delivery.

What is the minimum wall thickness you can cast?

The achievable wall thickness depends on the selected sand casting technology as well as the component geometry, flow length and overall design. For some applications, local wall thicknesses around 1.5 mm can be achieved, while other components may require thicker sections to ensure proper mould filling and casting quality. Each design is evaluated individually.

How long is the delivery time?

Delivery time depends on component geometry, quantity and the selected tooling and moulding solution. In a fast-track setup, first castings can typically be ready within 3–6 weeks. We assess each project individually and provide realistic lead times as part of the quotation process.

What are the benefits of sand casting?

Sand casting is a cost-effective manufacturing process for larger and more complex components, particularly in prototype, pre-series and medium-volume production. Compared to permanent tooling processes, sand casting offers lower tooling investment, greater design flexibility and the possibility to adapt tooling and moulding methods as project requirements evolve. Advanced sand casting technologies also enable complex geometries, internal features and thin-walled sections.

What materials can you machine?

We specialize in aluminium and magnesium, but also work with plastics and a range of other metals depending on the application. These components are typically produced alongside aluminium or magnesium parts, allowing us to deliver complete solutions from a single source. Our focus remains on lightweight, high-performance components.

How long is the delivery time?

Lead time depends on the starting point and complexity. CNC machining from billet can in some cases be delivered in as little as one week. Components based on casting processes combined with machining typically require longer lead times. We always focus on selecting the optimal manufacturing route to minimize overall delivery time.

Do you also offer inspection reports?

Yes, we offer inspection reports as part of the delivery. CNC machining and dimensional inspection are handled in-house, ensuring consistent quality, short communication paths, and reliable delivery times.

Can you also take care of surface treatments and assembly?

Yes, we can include surface treatments and assembly as part of the delivery. This includes processes such as SurTec 650, anodizing, Cerakote and powder coating. Through our established partner network, we ensure consistent quality, efficient coordination, and reliable delivery times.

How do I get a quotation?

Simply upload your CAD data and any available drawings or specifications. A brief description of your project is sufficient. Our engineering team will review the information and provide technical feedback together with a quotation.

What component sizes can be produced?

We can support projects requiring up to 4400-ton clamping force, enabling production of very large components.

Can you perform simulation before production?

Yes. We use advanced simulation tools to analyse filling behaviour, material flow and potential casting challenges before production begins. This helps optimise tool design and process parameters while reducing development risk.

Can you assist with design optimisation?

Absolutely. Early engineering input is often one of the most effective ways to improve manufacturability, reduce cost and minimise development risk. We regularly support customers with design reviews and casting optimisation.

Is die casting suitable for prototypes?

Yes. Die casting is often the preferred choice when realistic validation is required. Unlike many prototype processes, die cast components closely represent the material properties, geometry and functionality of production parts.

Can you supply fully machined parts?

Yes. We provide CNC machining, surface treatment, inspection, leak testing, assembly and other post-processing services. Components can be delivered as finished parts ready for testing or installation.

How quickly can you deliver die cast prototypes?

Typical lead times for die cast prototype components are between 6 and 15 weeks, depending on complexity, tooling requirements, material selection and post-processing needs.

What kind of production volumes does Formkon support in die casting?

Typical project volumes range from 50–2,000 prototype parts and up to approximately 5,000 units annually. Projects outside these ranges may also be suitable. We assess each project individually to ensure it is a good fit for both the application and our manufacturing setup.

Yes. We are flexible regarding alloy selection and can also support customer-specific or special alloys depending on project requirements.

What is the minimum wall thickness you can cast?

Investment casting is ideal for complex and thin-walled components. Depending on geometry, alloy, and part size, wall thicknesses down to approximately 1 mm, and in some cases even thinner, can be achieved. We use our experience in aluminium and magnesium investment casting to optimise gating and process parameters for lightweight components with high detail and dimensional accuracy. For extremely thin-walled geometries, we recommend sharing CAD data for technical evaluation, as achievable wall thickness depends on factors such as flow length, local geometry, and mechanical requirements.
