Investment casting for Pforzheim: Your 360-degree partner

Many construction projects are delayed because essential components are technically difficult to implement. We supply you with investment cast parts that allow you to meet complex requirements and receive fully functional parts ready for immediate use. You will benefit from personal support: from the first consultation, through a feasibility check to on-time delivery.

When investment casting is the better choice

Not every component can be economically milled, welded, or machined. Especially with complex geometries, limited installation space, or precisely defined material use, conventional processes quickly reach technical or economic limits.
In these cases, investment casting offers clear advantages. The process combines high design freedom with a variety of materials and consistent dimensional accuracy.

Typical starting situations:

Welded assemblies should be functionally simplified and manufactured as cast parts
Milled parts are too costly or technically difficult to realize
Round, organic or internal geometries are constructively required
Requirements for temperature behavior or corrosion resistance must be met

Our services

Technical consultation

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

Material selection and procurement

You will receive an objective recommendation for the right alloy and suitable material. Each melt is specifically composed in our production plants according to your specifications and ensures seamless traceability through spectral analysis and documentation. This way, your components always meet the required specifications.

Development and production of prototypes

For new projects, SBV Stahltechnik produces prototypes or sample parts on request. This allows you to check functions and dimensions at an early stage before series production starts. This minimizes the risk of incorrect developments and saves you costs.

Mechanical processing and surface finishing

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

Logistics and delivery

We offer you flexible logistics solutions: from delivery on call to intermediate storage in Germany. You determine batch sizes and call-off cycles according to your needs. This keeps you flexible in production planning and minimizes storage costs.

Heat treatment in our own stainless steel hardening shop

We perform heat treatments at our own factory in Germany. This ensures defined material properties and benefits from short throughput times. Delays due to external service providers are completely eliminated.

The investment casting process explained: step by step

Manufacture wax model & assemble wax trees

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

Manufacture ceramic shells and fire

The wax trees are dipped in liquid slurry in several steps and then sanded. This creates 5-8 layers of ceramic with differently coarse sands for flawless surfaces on the cast part and sufficient stability for the casting process. The dried ceramic mold is heated in an autoclave using steam, the wax melts out. Then the shell is fired at >1,000 °C before casting.

Cast & demold components

In 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 tree by vibration.

Separate casting tree & process components

The individual components are separated from the casting trees and the gates are ground. The components are then blasted, annealed, and pickled. If necessary, mechanical processing and finishing through coating or heat treatment take place now.

Materials & Properties

We produce investment cast parts from:

Stainless steel, including 1.4308, 1.4404, 1.4469
Aluminum for components with low weight and good corrosion resistance

The material selection is closely coordinated with you. It is based on the application medium, temperature load, mechanical stress, or cleaning requirements. In our stainless steel hardening shop, we optimize the material properties specifically for your application.

The investment casting process explained: step by step

Inquiry & Initial Assessment

Drawing and/or CAD model suffice. We check feasibility, material selection, and castability, including evaluation of the required tolerances in close consultation with our customers.

Consultation & Offer

Technical clarification, material consultation, and casting optimization: From this we create a solid offer including tooling costs, delivery time, and processing options.

Toolmaking & Prototypes

Upon assignment, we start with the manufacture of tools and first samples for dimensional inspection, possibly with initial sample inspection report (ISIR). Alternatively, small series or prototypes can also be produced without tools using 3D printers.

Series production & processing

Casting, demolding, mechanical processing, surface finish, and heat treatment, all from a single source.

Delivery & Logistics

Serial delivery according to blanket order, call-off, or one-time delivery. On request with buffer storage near the customer and individual packaging.
