Technical equipment
We support you in the realization of your ideas
One of the key steps in the production of a cast part is the design.
As with the selection of the material, the utmost care and expertise is also required here.
Only the optimum design combined with the precise arrangement of the casting system and mold will result in the best possible design for your casting.
The technical equipment with the design software Siemens NX incl.
CAM interface for NC machines and reverse engineering with GeoMagic (reverse engineering) guarantees the best results.
Data can be exchanged via Step, IGES or Pro-E.
Together, we incorporate the in-depth knowledge of our experts into the design of the casting you require, enabling us to design the downstream processes to be cost-effective and suitable for casting.
The simulation of the casting and solidification behavior of the casting with MAGMA Soft can contribute to further process and cost optimization.

Melting store
At the heart of our ultra-modern foundry are two hot blast cupola furnaces, which are operated in daily rotation.
The hourly melting capacity is 15 tons. We use this melting unit to melt cast iron with lamellar graphite (gray cast iron) and cast iron with spheroidal graphite (ductile cast iron).
The responsible use of resources and the environment is deeply rooted in our guidelines.
We therefore use the waste heat available to us from the ovens to reduce the plant’s remaining energy requirements.
Molding lines
Our modern molding lines and the experience of our employees guarantee you consistently high quality.
Horizontal molding line
1 Heinrich Wagner-Sinto molding line
Box size 1100 x 900 x 200 / 200 mm
Casting weights up to 150 kg
Vertical molding line
1 DISAMATIC 2130 C
Bale size 850 x 650 x 150 – 450 mm
Casting weights up to 50 kg
Core production
An accurately fitting core is just as important for the quality of a cast part as the model as a whole.
The production of the core for subsequent cavities in the workpiece is usually the first step in the production chain and requires foresighted planning.
Manufacturing process Coldbox
Core shooters 12 – 40 liters

- Dipping (color bath)
- Painting (overhead conveyor)
- Water-based paints
On the way to the ready-to-install cast part, a surface coating is often required to ensure corrosion resistance and to meet the visual requirements of our customers.
Here, too, the specification must be closely coordinated with the customer in order to ensure efficient component realization.
- the color
- the number of paint layers
- the thickness of the varnish and
- optimally align the chemical properties of the coating to the usage requirements of the component.
We make sure that our coatings meet our customers’ requirements and are sustainable and environmentally friendly at the same time.
To this end, we focus primarily on water-soluble coatings.
In our foundry, we can paint or prime your parts on an overhead conveyor system.
In addition, we can also efficiently realize other customer requirements such as KTL coatings with external partners.

This process step plays a key role in determining the quality of the subsequent cast part.
Our qualified model makers use their expertise and dexterity to create models made of aluminum, plastic, brass and steel with the highest dimensional accuracy according to your 3D data.
The materials are selected taking into account the optimum cost and benefit aspects.
In addition to the creation of new pattern equipment, our range of services also includes the ideal casting design and preparation of customer patterns as well as their maintenance.
True to our company philosophy: WESO – The plus in casting
The use of state-of-the-art technologies is a matter of course for us.
This includes CNC machining, CAD/CAM design, CNC-controlled coordinate measuring machines and optical measuring methods, including for monitoring the service life of your models.

We offer our customers the plus in casting and would like to offer our customers many value-added steps from a single source.
In addition to manufacturing the raw cast parts, we are also happy to take on the subsequent machining of the parts.
Our aim is to be able to supply the entire portfolio from a single source.
This reduces the complexity of our customers’ supply chain:
- fewer suppliers
- Shorter process times
- Clear responsibility
- Opportunity to optimize the entire value chain
- Lower logistics costs
We process the castings on more than 20 modern milling and turning machining centers in order to supply our customers with ready-to-install parts.
We are also happy to support our customers in their growth and invest in new machines in order to offer new processing and value-added scopes.

Your cast part receives the finishing touches in the casting post-treatment!
After solidification, the process of creating the optimum casting is not yet complete.
Further steps are required to fulfill customer requirements and deliver a usable casting.
We offer you the following processes for casting post-treatment:
- Rays
- Manual grinding
- Automatic grinding
The specific design depends on the requirements of the component.
The aim is always to meet the requirements of our customers as economically as possible.
Blasting the castings
During blasting, the castings are blasted with a metallic abrasive to remove deposits such as ore deposits, molding sand, core sand or scale and to achieve high-quality surfaces.
The blasting of castings is carried out in our foundry in three different systems, whereby we use interlinked systems to provide automated blasting with minimal handling:
- Horizontal blasting in the interlinked wire belt blast machine
- Suspended blasting in the interlinked overhead conveyor blast machine
- Troughed belt blast machine for barrel-shaped castings
Clean cast iron
After blasting, the cast parts are cleaned.
This involves removing excess parts from the castings and deburring them so that they are ready for installation or further processing.
In addition to manual fettling at our modern manual workstations, we also use Koyama grinding robots to fettle the castings efficiently and ergonomically and ensure a consistent fettling result for our customers.

All services up to the ready-to-install assembly from a single source
Thanks to our many years of experience in heating technology, we have built up a component production facility in which we integrate our customers’ cast parts into ready-to-install assemblies and components.
In lean assembly lines with directly connected material supply for assembly material, we support our customers in focusing on their core competencies.
Our services range from the initial pre-assembly of cast parts to the assembly of ready-to-install functional modules, including the sourcing of assembly components.
This is how we help our customers:
- Reduce your complexity in production
- Reduce inventories
- Utilize capacities and resources efficiently
On request, we can also carry out initial functional tests on our assembly lines.

The choice of the right material depends on many aspects that every designer has to deal with when designing a new product.
The material gray cast iron has excellent properties.
There are several reasons for this, of which the most interesting for the user is probably the economic efficiency as the sum of material, manufacturing, operating and disposal costs.
However, the properties of this material group are also technically attractive, for example the adjustable, favorable mechanical, physical and technological properties.
The excellent damping behavior in particular makes this material suitable for applications in dynamically loaded components.
It also has good casting properties, which allow the production of cast parts with highly complex geometries, excellent surface quality and high reproduction accuracy.
It is also a robust material that is highly insensitive to fluctuations in influencing variables, manufacturing and application conditions.
When manufactured and used properly, cast iron with flake graphite as well as with nodular graphite is a high-performance material without major sensitivities, which opens up a wide range of applications even today in the high-tech age.
Modern construction methods and manufacturing processes also give this material lightweight construction potential that can be exploited in future applications.
At WESO, we offer you these high-quality materials:
- Gray cast iron (EN-GJL)
- Spheroidal graphite cast iron (EN-GJS)
