Our services

Development Partner

Cross-border qualification for boundless innovation

In recent years, Wolf Industries has established itself as a development partner for our customers. The development department located in Regensburg centrally coordinates development projects across the company group and advises our international customers on casting optimization and component design.

In the course of simultaneous engineering projects, Wolf Industries has collaborated closely with our customers to develop numerous components from the prototype stage to serial deployment. These components are implemented in our factories in China and Hungary.

Constant exchange of innovation with Regensburg, as well as the very close collaboration with the foundry faculty at the University of Miskolc, make Prec-Cast unique in Hungary.

The technical departments of the factories are supported by competent project teams that oversee the product lifecycle from prototype to full-scale production. Even after SOP (Start of Production), products are continuously improved, quality-managed, and optimized for economic aspects through ongoing improvement measures.


Prototypes made from sand casting, soft molds, or milled from solid blocks

The Wolf Group supports its customers from the initial stages of development by supplying prototypes. Various methods, either internally or through external partners, are available for this purpose. Depending on the application and specifications, initial components can be produced using rapid prototyping, sand casting, or even die casting, and can be further processed in-house.

In each case, the goal is to be involved in the development of the component from the beginning, aiming to fully support the customer and gather the best possible experience for the later series production process at an early stage.

Internal toolmaking

Tailored and fast solutions for individual requirements

At all locations within the group, Wolf Industries has its own toolmaking capabilities, which significantly contribute to the flexibility and effectiveness of the company and ensure continuous growth of expertise. While tool maintenance is primarily conducted in Hungary and China to ensure smooth casting processes, at the headquarters in Regensburg, die casting and deburring tools, as well as various fixtures, are custom-developed for customers and produced rapidly on state-of-the-art equipment.

Tool adaptations during acquisition projects can also be realized in a very short time to ensure uninterrupted series supply to the customer.

Die casting capabilities

Opportunities for a comprehensive range of products

Wolf Industries currently has the capability to produce aluminum die-cast parts across 60 casting cells with clamping forces ranging from 200 tons to 3,000 tons.

The Prec-Cast site in Hungary comprises 50 die-casting machines, representing the largest portion. These machines are equipped with varying degrees of automation, allowing for cost-effective production of products with very low volumes as well as highly economical manufacturing of high-volume series components on fully automated die-casting cells.

An automated spraying process, process monitoring, and vacuum support on many machines ensure consistent quality, while individual DMC markings ensure traceability.

At the Chinese site Prec-Cast Zhongshan, die casting cells operate with clamping forces ranging from 400 tons to 1,000 tons. These cells produce components for both the local Chinese and international markets, adhering to the same high standards of quality as in Europe.

heat treatment

Heat treatment for different component properties

To optimize the mechanical properties of components and meet our customers’ high specifications, we subject some parts to heat treatment. We are capable of meeting various stages and customer requirements (T5, T6, and T7) using either a batch furnace or a continuous furnace with air quenching.

Component-specific and optimized heat treatment fixtures ensure minimal distortion during heat treatment. However, since some distortion in the components cannot be completely avoided, parts undergo blister testing followed by 100% dimensional inspection and a straightening process. Depending on requirements and volume, we utilize manual, semi-automatic, or fully automated straightening and measuring systems.

surface treatment

Shot blasting, vibratory finishing, and robotic grinding cells

For leveling out technically induced surface cracks, we employ traditional surface treatments such as shot blasting and vibratory finishing.

To achieve repeatable accuracy of mating and seating surfaces for structural components, we utilize robotic grinding cells. These cells are also employed for components that have high visual surface requirements, for example, prior to powder coating.

CNC machining

Compelling quality through state-of-the-art machining centers

Within the group, raw parts are mechanically processed on over 50 CNC machines. Standard machines of various sizes and types, as well as multi-spindle systems, provide high flexibility and depth of machining capability. This allows us to handle CNC milling components for high-volume projects as well as small batches with high complexity. Additionally, rotationally symmetric parts are manufactured on partially or fully automated systems.

Various product-specific special machines and rotary indexing machines also ensure extremely fast and economical machining of components with very high production volumes.

A specialized team takes full responsibility for process and quality management for the entire product family, thereby developing a completely new understanding of component requirements. A well-planned material flow through all process steps enables optimal manufacturing with consistently reliable quality.

First sample inspections and series measurements across the entire company group are conducted using modern 3D coordinate measuring machines, as well as process verification through CAQ (Computer-Aided Quality) systems.


Highest standards for achieving technical cleanliness

In all areas, but especially in electromobility, the requirements for technical cleanliness (TecSa) are continuously increasing.

To meet these requirements, component-specific special washing machines are used. In some cases, high-pressure water jet systems are used upstream to remove secondary burrs from CNC machining.

To prevent subsequent contamination from metallic and organic particles, the continuous washing systems lead into specially enclosed clean zones. Here, final inspections, possible leak tests, assembly processes, and packaging are conducted.

The strict requirements are ensured through regular filter replacement and continuous bath cleaning, with verification done through residual dirt analysis.

Leak testing and assembly

Ready-to-install systems for our customers

Wolf Industries offers its customers components in ready-to-install condition: from simple bolts and threaded inserts to two-component sealing applications and fully assembled modules. Force-path monitored units, component-specific leak testing systems, electronic queries, and Poke Yoke concepts ensure the completeness of assembly and inspections.

Complete assemblies or successful test results are marked on the component or stored in the system using the existing component DMC (Data Matrix Code) to ensure traceability.

For the desired finish

System supplier with technical and decorative coatings

As a system partner, Wolf Industries offers component and surface finishing upon request.

While decorative powder coatings can be done in-house at the Prec-Cast site in Hungary, Wolf Industries collaborates with selected partners across its locations for technical surface treatments as needed.

Depending on customer specifications, various processes are used, primarily for corrosion protection of the components.

These include conversion coating and cathodic dip painting for structural components, as well as chromating, anodizing, and other technical surface treatments for components used in truck braking systems, air supply systems, and electromobility applications.


The right material for every application

Different alloys are used based on varying requirements for the functionality of components or the environmental conditions they are exposed to.

The mechanical properties can be further enhanced if necessary through post-treatment heat treatment.
