Investment casting parts: Solutions for complex geometries and high requirements

Many design projects are delayed because crucial components are technically difficult to realize. We provide you with investment casting parts that meet complex requirements and deliver ready-to-use functional parts. You benefit from personalized support: from the first consultation, through a feasibility study, to on-time delivery.

When conventional manufacturing reaches its limits

Conventional methods, whether machining or forming, often reach clear limits with demanding components. Especially delicate structures, complex geometries, or high functional integration can hardly be realized economically with milling, welding, and other processes. Investment casting parts from SBV Stahltechnik provide possibilities and solutions for implementing your project

How does the investment casting process work?

We use a multi-step process to manufacture investment casting parts from stainless steel, steel, or aluminum. The starting point is a wax model, which we enclose with a ceramic mold. We pour the metal into this mold. The main steps:

Produce wax model & assemble wax clusters

A precise wax model of the component is produced using a wax tool or 3D printing, then several wax models are assembled into a wax cluster

Manufacture and fire ceramic shells

The wax clusters are dipped in liquid slurry in several steps and then sanded. This creates 5-8 layers of ceramics with different coarse sands for flawless surfaces on the cast part and sufficient stability for the stress during casting. The dried ceramic mold is heated in an autoclave using steam, melting out the wax. Then the shell is fired at >1000 °C before casting.

Cast & demold components

During casting, liquid metal is poured into the fired and still >1000°C hot ceramic mold, after solidification and cooling, the ceramic is destroyed and separated from the casting cluster by vibration.

Separate casting cluster & process components

The individual components are separated from the casting clusters and the sprues are ground. Then the components are blasted, annealed, and pickled. If required, mechanical processing and refinement by coating or heat treatment take place now.

What makes our investment casting parts special

With investment casting parts from SBV Stahltechnik, you gain technical possibilities not offered by traditional manufacturing processes. These properties form the basis for individual solutions precisely to your specifications.

Geometric freedom

With investment casting, even very complex shapes can be realized. These include complex interiors, curves with homogeneous transitions, or organic structures. The process depicts complex forms with fine microstructures and almost unlimited shape freedom.

Dimensional accuracy in series

Components are manufactured according to your tolerance specifications. Dimensional variations between parts in a series are very small due to our stable processes. This ensures stable functionality, continuous dimensional accuracy, and less waste.

Material variety according to requirements

We manufacture investment casting parts from stainless steel, steel, or aluminum, and recommend the appropriate alloy. This allows you to achieve specific properties such as temperature resistance or media resistance.

Function integration

Many functional elements, such as brackets, snap-fits, or reinforcements, can be directly depicted in investment casting without additional manufacturing effort.

Elements such as bores, gears, or locks are already integrated into the casting with appropriate tolerances. Fits, threads, or critically toleranced functional areas are mechanically processed to ensure the highest precision and fit accuracy.

Fast decision processes: Responsiveness when it matters

Thanks to flat hierarchies and clear responsibilities, we respond quickly to new requirements or short-term changes. This allows us to efficiently implement adjustments even during the ongoing project without lengthy consultations. Whether design changes, delivery reschedule, or technical adjustments: You benefit from short communication paths, quick decisions, and a project flow adapted to your pace.

Why SBV Stahltechnik is the right partner for your investment casting parts

Technical consultation

We accompany you from the first idea to the final solution. Together, we analyze the requirements, assess technical feasibility, and develop the optimal design. This guarantees a functional and economical implementation of your component.

Material selection and procurement

You receive an objective recommendation for the appropriate alloy and material. Each melt is specifically composed according to your specifications in our production facilities and ensures complete traceability through spectroanalysis and documentation. This ensures that your components always meet the required specifications.

Development and production of prototypes

For new projects, SBV Stahltechnik manufactures prototypes or sample parts on request. This allows you to test functions and dimensions early before series production starts. This minimizes the risk of misdevelopments and saves you costs.

Mechanical processing and surface finishing

Depending on the requirement, mechanical processing, drilling, milling, or grinding of your components is performed. We coordinate these steps in our own facilities, ensuring quality control. Milling, drilling, or polishing according to drawings ensures you receive assembly-ready parts from a single source.

Logistics and Delivery

We offer you flexible logistics solutions: from delivery on demand to interim storage in Germany. You can determine batch sizes and call-off cycles according to your needs. This allows you to remain flexible in production planning and minimize storage costs.

Heat treatment in our own stainless steel hardening shop

We perform heat treatments in our own facility in Germany. This provides you with defined material properties and benefits from short turnaround times. Delays caused by external service providers are completely eliminated.
